XRF, NIR and FTIR: Your Complete Mining Solution

In the high-stakes world of Australian mining, accurate and reliable analysis is the bedrock of success.

With evolving technologies, the mining industry has seen a remarkable shift towards non-destructive, portable analysis tools that promise to revolutionise the way you explore, extract and analyse valuable resources.

This article delves into the importance of robust analytical solutions and explores the three most popular and effective technologies: XRF, NIR and FTIR.


What Are The Best Mining Analysis Technologies?

Both greenfield and brownfield mining operations demand precise insights into elemental composition and mineral content.

Robust, portable and non-destructive analysis technologies like XRF, NIR and FTIR empower your team with real-time data that informs critical decisions on-site.

But rather than thinking about them as competing technologies, think of them as complementary.

Each technology is better suited for different applications, so instead of asking which one is better, ask whether XRF, NIR or FTIR are more suited to your needs.

1. X-Ray Fluorescence (XRF)

What is XRF?

X-Ray Fluorescence (XRF) is a non-destructive analytical technique to determine the elemental composition of materials, making it ideal for elemental analysis. Handheld XRF or Portable XRF (PXRF) is now widely used across the mining industry for real-time, in-field mining analysis.

How does XRF work?

XRF analysers determine the chemistry of a sample by measuring the fluorescent or secondary X-ray emitted when excited by a primary X-ray source.

Every element present in a sample produces a unique set of characteristic fluorescent X-rays (also called a “fingerprint”), which is why XRF spectroscopy is often used for qualitative and quantitative analysis of material composition.

2. Near-Infrared (NIR)

What is NIR Spectroscopy?

Near-Infrared Spectroscopy is an accurate, reliable, rapid and non-destructive analysis method that requires no sample preparation. NIR is one of the most used procedures as it is both efficient and has a wide range of applications across mining, medicine, agriculture and many other industries.

How does NIR work?

NIR Spectroscopy instruments detect the molecular overtone and combination variations of the specific wavelengths of NIR light absorbed by specific organic molecules.

NIR is best used for mineral analysis in the near-infrared region of the electromagnetic spectrum (from about 350 nm to 2500 nm) to identify compounds and materials.

Learn more about NIR.

3. Fourier Transform Infrared (FTIR)

What is FTIR Spectroscopy?

FTIR is named for its use of the Fourier transform mathematical process. It is a versatile extension of existing Infrared techniques that provides fast, accurate results in a unique spectral range. This makes it especially complementary when paired with NIR. FTIR is ideal for mineral analysis in the mid-infrared region (4000-400 cm-1).

How does FTIR work?

FTIR uses the mathematical transform called the Fourier Transform, which decomposes functions depending on space or time into functions depending on spatial or temporal frequency. FTIR technology converts raw data into an infrared spectrum of absorption or emission of a solid, liquid or gas.

Getting Transparent About Root Phenotyping

Plant phenotyping is a vital aspect of agricultural research and crop management.

It involves the comprehensive study of plant traits and their responses to environmental conditions. Among these traits, root phenotyping stands out as a critical area of focus.

This is especially true for regions like Australia where drought conditions pose significant challenges to crops. The ability of roots to efficiently find and absorb water is paramount in these environments.

In this post, we will explore the importance of accurate and efficient root analysis during the plant phenotyping process, with a special emphasis on Australia’s drought conditions. We will also delve into the current challenges faced in root analysis and how the PhenoAIxpert can revolutionise root phenotyping.

Why is Plant Phenotyping Important?

In Australia’s drought-prone climate, root phenotyping is vital. It helps researchers and farmers understand how plants adapt by assessing root growth and water absorption.

This plays a crucial role in improving crop yields by identifying plants with efficient water-extraction root systems. In this way, accurate root analysis is essential to the agricultural sustainability of these harsh regions.

Challenges Associated with Root Analysis

Vital as it may be, analysing roots can be the cause of many challenges, and these are compounded when trying to perform particularly precise phenotyping. Some of these challenges include:

1. Lack of visibility

Roots are hidden beneath the soil and are difficult to observe directly. Traditional methods of root analysis often require uprooting plants, which not only disrupts the growing process but can also lead to the loss of important data.

2. Sample Destruction

Another issue with digging up plants to analyse their roots is that this will often damage, if not ruin the sample, making it impossible to track changes over time and tainting the accuracy of your results.

3. Hefty Cleaning

Samples preparation can be a time-consuming process as it requires careful cleaning to remove soil and debris without damaging the roots. The traditional methods for root analysis are not only labour-intensive but also lack the ability to perform non-destructive, real-time assessments.

This is where innovative technologies like the Lemnatec™ PhenoAIxpert come into play.

Prospecting with Precision: How Rare Earth Element Detection Enhances Mining Exploration

Mining exploration plays an important role in the Australian mining industry, particularly when it comes to Rare Earth Element (REE) detection. These valuable resources are in high demand due to their extensive applications in various industries, however, locating REE deposits can be a challenging task without the right tools and technology.

Fortunately, there is a game-changing solution: the Niton XL5 Plus Analyser.

In this article, we will delve into the significance of REEs, the process of exploratory mining, and how the accurate and fast analysis provided by the Niton XL5 Plus can significantly improve the search for these valuable elements.

What are Rare Earth Elements?

Rare Earth Elements are a group of 17 chemically similar elements found in the Earth’s crust. They encompass lanthanides such as cerium, europium, and lanthanum, along with two additional elements: scandium and yttrium. Despite their name, REEs are not actually particularly rare, but are instead dispersed in low concentrations throughout various minerals.

Why are Rare Earth Elements Sought After?

REEs have become increasingly sought after due to their major role in modern technology manufacturing.

These elements are essential to produce high performance:

  • Magnets
  • Catalysts
  • Lasers
  • Batteries

That’s why they are so crucial for increasingly popular renewable energy systems, including electric vehicles, telecommunications products, and defence technologies. As industries transition towards sustainable practices, the demand for REEs continues to rise.

What is Exploratory Mining?

Also referred to as Greenfield mining, exploratory mining plays a crucial role in locating and then extracting REEs.

Considering REEs are not typically found in large deposits, locating them is a complex process. Exploratory mining involves searching for trace amounts, otherwise known as “pathfinders” that indicate the presence of REEs in the earth’s core. Identifying these pathfinders accurately can significantly improve the success rate of mining operations.

The Benefits of Accurate and Fast Analysis

The benefits of accurate and fast REE analysis are plentiful.

Informed Decisions

Firstly, it allows mining companies to make precise and informed decisions, minimising the risk of drilling in the wrong locations and maximising the chances of discovering valuable REE deposits. This efficiency translates into significant cost savings, as resources are not wasted on unproductive sites.

Faster Operations

Moreover, faster mining exploration accelerates the timeline for potential mining operations. By leveraging advanced technology and improving the speed of their exploratory operations, mining teams can gain a competitive edge, establish their expertise in REE exploration, and attract lucrative partnerships and investments.

Effective Rare Earth Element detection is particularly valuable and makes for a fantastic commercial opportunity in a world that is increasingly interested in renewable energy sources and other technological and telecommunications products.

The Consequences of Exploring Without the Right Tools

On the other hand, conducting REE exploration without the right tools and therefore without fast analysis can have severe consequences for Australian mining companies.

Inaccurate Analysis

Inaccurate readings and unreliable data can lead to costly drilling in non-productive areas, wasting valuable time, money, and resources for the teams involved.

Reputation Damage

Additionally, a lack of precise analysis can damage a company’s reputation, hampering potential partnerships and investment opportunities long into the future. The absence of accurate tools also increases the likelihood of missed REE deposits, limiting the company’s growth potential, competitive advantage and over a long enough period their bottom line as well.

Slower Operations

Finally, the delayed identification of pathfinders and therefore REEs will prolong the lucrative exploration phase, resulting in slower project development and potentially lost market opportunities – after all, exploration is a necessary precursor to extraction.

Therefore, investing in the right Rare Earth Element detection tools is crucial to mitigate these detrimental consequences and ensure successful Rare Earth Element detection.

Case Study: Screening for Asbestos in Tuvalu with the MicroPHAZIR AS

Case Study: Screening for Asbestos in Tuvalu with the MicroPHAZIR AS

The health risks of asbestos are well known, so much so that its use was officially banned in Australia in 2003.

Since then, extensive work has been conducted to remove asbestos where possible or to educate people on how to leave asbestos undisturbed. 

Unfortunately, its widespread presence in buildings and objects make it difficult to identify and avoid. 

The problem is, many smaller nations don’t have the resources or best-practice awareness that Australia has, and these nations remain vulnerable to the scourge of asbestos.

Asbestos on Tuvalu

Tuvalu is a Polynesian archipelago nation in the Pacific, about halfway between Australia and Hawaii. Like many other island nations, asbestos was used widely throughout the country’s infrastructure in the 20th Century and remains a risk for its citizens today. 

The Tuvalu Department of Waste Management (DWM) has been working tirelessly to identify, secure or remove asbestos throughout Tuvalu’s nine islands, but they are facing significant challenges. 

Lack of Labs

Tuvalu doesn’t have the laboratories required to test the large number of asbestos samples taken during clean-up efforts. This means the DWM is constantly being held up by lengthy lab turnaround times.

While these delays are necessary to keep their operators safe, they are still incredibly frustrating and slow down progress. 

Lack of Experts

The other resource shortage in Tuvalu is experts who can safely identify and dispose of asbestos. 

The Tuvalu island chain is relatively isolated and it can be difficult and costly to get experts to visit. That means when they do have them, they need to make the most of it!

A Possible Solution

PacWaste Plus programme technical offers, supported by consultant Ms Samantha O’Callaghan of HIBBs, visited Tuvalu on an asbestos identification mission in March.

What was different this time?

They were trialling a Thermo Fisher microPHAZIR AS Asbestos Analyser.

The Thermo Fisher MicroPHAZIR AS

The MicroPHAZAER AS is an industry-leading asbestos detection tool. With its simple point-and-shoot function, and accurate results delivered in just 10 seconds, it lets operators test for asbestos quickly and safely. . 

To screen a site, operators simply conduct a series of scans at different points, and if the results are negative they can declare an area safe. 

If the results are positive, they can send the sample away for lab confirmation, safe in the knowledge that they haven’t been exposed by needing to take a sample and disturb the contaminated object. 

Screening in Tuvalu

Man using a MicroPHAZIR device to scan a sample

The rapid testing ability of the microPHAZIR AS could make a real impact for the DWM’s initiative. 

“Undertaking asbestos assessments is very difficult in Tuvalu.  We do not have laboratory equipment and it is difficult and expensive for external specialists to visit our outer islands to complete assessments,” said Mr Epu Falenga, Director of Waste Management.

With the microPHAZIR AS, the hope is that much wider areas can be covered in a much shorter time period. 

“By testing this new technology and having our own staff experience the various steps to effectively undertake asbestos sampling, empowers us to roll out an assessment ourselves across our nine islands.” Mr Falenga continued. 

The Trial

Conference with people discussing the MicroPHAZIR device

While hopes are high that the microPHAZIR AS will be effective, testing must be completed to ensure it is compatible with Tuvalu’s conditions. 

“We need to be certain on the efficacy of this tool, especially in our island settings.” said Mr Falenga. 

As part of the trial, Ms O’Callaghan took samples determined to be ‘positive’ for asbestos and sent them to Australia for laboratory confirmation. A capacity building workshop was also conducted with the DWM team, as well as ten other government stakeholders from the Department of Customs and Department of Surveying.

The hope is that the sample determinations will be corroborated in the lab, and that the combined team in Tuvalu will already have the skills required to operate their devices. 

To Be Continued

The cause to rid Tuvalu of asbestos is a noble one, and the outcome of this trial will be relevant for the wider Pacific Island region.

For the operators at DWM, any developments that make asbestos detection safer, faster and more accurate will be welcome.

A Tale of Two Spectra: The Difference Between NIR and FTIR

Near-Infrared Spectroscopy (NIR) and Fourier Transform Infrared Spectroscopy (FTIR) are two molecular analysis technologies that are used in a wide range of industries – especially mining.

While NIR is a well-known and well-established technology, FTIR is often considered the new kid on the block, and you may not know much about it.

So, which one is the best for your needs?

Read on to learn the difference between NIR and FTIR.

What is NIR?

Near-Infrared Spectroscopy (NIR) is a non-destructive analytical technique that identifies the molecular composition of a sample.

When the light in the near-infrared region is applied to the sample, the amount of light absorbed or reflected at different wavelengths can be measured. This can be used to identify the presence and abundance of different elements.

What is FTIR?

Fourier Transform Infrared Spectroscopy (FTIR) is also a technique used to identify and analyse the molecular structure of a material.

Unlike NIR, FTIR applies fully infrared light to the sample and measures how much light is absorbed in different wavelengths. Using the Fourier Transform method, it can analyse the entire spectra simultaneously, improving the speed and scalability of its analysis.

What’s the Difference Between NIR and FTIR?

The main difference between NIR and FTIR is the spectral range they use for analysis. NIR uses light in the near-infrared region (approximately 350-2500 nm), while FTIR uses light in the mid-infrared region (approximately 4000-400 cm^-1).

This difference in wavelength range affects the types of samples that can be analysed. This means NIR and FTIR aren’t like-for-like substitutes, but are instead complementary.

Benefits of NIR

NIR is best used for testing a larger sample size, where compositions aren’t exceedingly complex. This makes NIR a preferred method for quantitative analysis, where the aim is to idenitfy the main components of a sample range quickly.

NIR is also able to analyse all three states of matter: solids, liquids and gases. This means along with identifying the composition of a sample, it can also detect the moisture content and air pockets which can effect what the sample is worth and how it may need to be processed.

It’s ability to analyse wide ranges of samples across different states of matter makes it ideally suited to greenfield mining exploration.

Benefits of FTIR

The biggest strength of FTIR is it can assess an impressively wide spectra which lets it identify trace elements like chemicals and other contaminants.

Along with trace elements, it can also provide far more detailed breakdowns of sample composition because it can examine the entire spectra simultaneously, rather than having to examine individual wavelengths.

The ability to assess the composition of samples to such a precise level opens up a lot of opportunities in the mining industry. Not only does it shed more light on the true value of a sample, it can also reveal the transformation history of the minerals in the area.

The other benefit of FTIR is the speed of its analysis. The Fourier Transform method means the entire spectrum is analysed as a whole, saving time from having to measure singular wavelengths.

NIR vs FTIR: Which is Better?

In this case, it isn’t ‘which is better’, but rather which do you need? Either NIR or FTIR could be more suitable depending on the application.

For analysis of larger sample sizes, NIR is likely to be more suitable. However, for a more in-depth breakdown of sample composition, FTIR may be your preferred solution.

A Guide to Portable XRF Geochemistry in Mining

Geochemistry analysis is an incredibly important part of the mining industry. It is relevant to every stage of a mine’s life cycle and needs to be fast and accurate enough to avoid costly delays.

Portable XRF geochemistry analysers are the solution and are making mines more profitable all across Australia. So read on to learn how these incredible devices are applied to mining.

What is XRF?

X-ray Fluorescence Spectroscopy (XRF) is a non-invasive method for measuring the elemental composition of materials.

It uses a spectrometer to detect and measure X-Rays emitted by the atoms of a sample that has been irradiated. Depending on the element, the intensity of the fluorescent radiation it emits will change, allowing it to be identified.

What is Portable XRF Geochemistry?

Portable XRF geochemistry uses the same technology as regular XRF, except it’s calibrated to a specific range of elements. For example, geochemistry is most often applied to mining industries, so these portable XRF devices will be calibrated to detect both the desired elements and also commonly occurring contaminants.

How does Portable XRF Geochemistry Work?

To use portable XRF analysers in the field, a small portion of the sample is placed in the analyser’s sample chamber. The instrument then fires X-Rays at the sample. The device will then measure the resulting energy of the emitted radiation. For the final stage, the analyser then processes this information and compiles a composition report.

This gives the operator insight into several things, including:

  • The composition of the sample
  • The concentration of the elements they are looking for
  • The concentration of undesirable elements
  • The presence of any contaminants

The speed and accuracy of portable XRF geochemistry make testing in the field simple and effective. That’s why it has become one of the most popular and useful analysis methods in the mining industry.

How is Portable XRF Geochemistry Used in Mining?

Portable XRF geochemistry is applicable to all stages of the mining process.

Exploration

The initial phase of mining is either greenfield or brownfield exploration. XRF is especially useful at this stage because surveyors need to be able to take samples in the field and on the move. Because of its rapid results, samples can be taken over multiple days without costly interruptions waiting for lab results.

Resource Estimation

Once exploration has detected the presence of the desired minerals, the site needs to be assessed. Starting a new mine is an enormous financial undertaking so sites need to be rich enough to be worth the investment.

Using portable XRF geochemistry, testing the composition of samples over a wider area will reveal whether the site is worth pursuing.

Ore Processing

While ore is being mined, it is important to know the composition to determine how best to process it. Portable XRF geochemistry is so fast and accurate that mining companies can react quickly if the composition of the ore demands a different process.

Environmental Compliance

Mining companies must abide by strict environmental compliance legislation, especially regarding pollutants and contaminants.

Portable XRF geochemistry is an effective tool for testing soil and water samples to assess the risk of run-off which could risk breaching the rules.

On a Whole New Wavelength: What is FTIR and How Does it Work?

On A Whole New Wavelength: What Is FTIR And How Does It Work?

Meet the new kid on the spectroscopy block – FTIR.

Whether you work with polymers, minerals, environmental science or even historical artefacts, FTIR can be applied to transform your analysis capabilities.

Read on to learn what FTIR is and how it works!

What is FTIR?

FTIR, or Fourier Transform Infrared is a form of spectroscopy that utilises infrared light to identify the chemical composition of a sample. Unlike other forms of infrared spectroscopy, FTIR analyses the entire spectrum of light at once, rather than individually.

How Does FTIR Work?

FTIR analyses the elemental composition of a material sample. It works by projecting a beam of infrared light through the sample and measuring the amount of light absorbed at different frequencies.

This absorption spectrum is unique for different molecules, with molecules belonging to different elements absorbing light at specific frequencies. The absorption spectrum is then transformed into a more detailed spectrum through the Fourier transform method. This allows for the identification of specific elements in the sample.

What Are the Benefits of FTIR?

FTIR offers several key benefits over other forms of infrared spectroscopy.

More Detailed Spectral Range

FTIR is highly accurate and provides an impressively detailed spectra that allow for the identification of even trace amounts of chemical compounds. This is because unlike regular Infrared technologies, the transform process makes the spectrum even more detailed than simply studying individual wavelengths.

Faster Analysis

Regular Infrared technology analyses portions of the spectrum individually. However, the Fourier transform process allows the entire spectrum to be analysed simultaneously, making analysis much faster.

Different Sample Forms

Fourier Transform Infrared has the ability to analyse samples across the three main states of matter: solids, liquids and gas. This gives it a significant advantage because you don’t need to conduct different methods of analysis for different sample states. If you are out in the field, you can test any sample you come across in the environment.

Non-Destructive

FTIR is non-destructive, meaning samples can be analysed without damaging them, making it ideal for use in industries where samples must be handled delicately, like historical artefact analysis. It’s also a safer technology for testing potentially harmful or toxic samples, as the operator doesn’t have to disturb or handle them.

Which Industries Can Apply FTIR?

FTIR is a useful technology for a wide variety of industries.

Polymers and Coatings

FTIR is used to identify the chemical composition of polymers, as well as to analyse the properties of these materials, such as their thermal stability. It can also help detect the presence of harmful contaminants in coatings, such as lead.

Environmental Science

Because of its ability to test samples in solid, liquid and gas form, FTIR is uniquely equipped to handle all types of environmental analysis. This can include testing soil, water or air contaminants.

Mineral Identification

The wide detection range of FTIR makes it a vital tool in the field of mineral analysis. Not only can it positively identify the presence of specific minerals, it can also measure their quality and purity with a high degree of accuracy.

Historical Artefacts

Historical artefacts, especially paintings, require extreme care when being tested. They are often priceless and taking or damaging samples is unacceptable. FTIR detects non-destructively, and can accurately assess the composition of artefacts. This is especially useful for detecting painted over sections of paintings, or level of degradation within metallic artefacts.

The Agilent 4300 Handheld FTIR Analyser

Fool’s Gold: How Precious Metal Testing Saves You From Being Swindled

Fool’s Gold: How XRF Precious Metal Testing Saves You From Being Swindled

Precious metals are, as the name would suggest, very expensive commodities. From jewellery to luxury household items, they are highly sought after and extremely rare.

The problem is, just like most naturally occurring metals and minerals, their quality depends on the purity of their composition. This means knowing the precise quality of what you’re buying is vital if you want to stay profitable in the precious metals industry. 

Read on to learn how precious metal testing, specifically with X-ray fluorescence (XRF), can save you from being swindled. 

What are Precious Metals?

Precious metals are elements that aren’t naturally abundant. As with most commodities, supply and demand affects the price. In this case, precious metals are extremely expensive because their supply is scarce while demand for them is high.

Specifically, the four main precious metals are:

  • Gold
  • Silver
  • Platinum
  • Palladium

Of these four, gold is the most recognisable and universally sought after, especially for its use in jewellery. 

What is Precious Metal Testing?

Precious metal testing aims to identify the purity of an alleged precious metal sample. While a precious metal may look pure, most samples are alloys, meaning they are mixed with other elements or other precious metals. 

For example, gold has five common alloys to be aware of:

  • Fine gold – 99.9% pure gold
  • Gold alloy – Gold mixed with other elements
  • Yellow gold – silver alloy
  • Rose gold – copper alloy
  • White gold – palladium or nickel alloy

To accurately price these alloys, you need to know specifically how much gold is in the alloy. Otherwise, you may be paying for more gold than you are actually receiving. With the price of gold increasing, this isn’t a mistake you can afford. 

Precious metal testing becomes even more important when you consider the gold is likely a part of an object, such as an inlay on a piece of jewellery. This makes it even more difficult to test without having to destroy the object by removing the gold component. 

Which Technology is the Best for Precious Metal Testing?

With the stakes so high, you need to know that your precious metal testing solution is highly accurate and can provide instant results. 

XRF is widely accepted in the industry as the best precious metal testing technology, especially because it doesn’t damage the sample. 

Using an X-ray, it excites the sample and measures the fluorescence emitted by it. Each element creates a different type of emitted X-ray, which allows for detailed measurement of the composition of the sample. Only XRF can test quickly, precisely and non-destructively in such an intuitive and easy-to-use way. 

Precious Metal Testing with XRF 

XRF precious metal testing is big business and comes with many benefits. 

Saves Your Money

One of the most common precious metal testing methods for gold is acid testing. But there are two major drawbacks that could cost you a lot of money. 

Firstly, the acid tests are deemed ‘safe’ for the sample because they only damage it if it’s fake. But in pawnbroking or jewellery industries, just because a sample isn’t real doesn’t mean the object is worthless. 

The owner may still like the item even if it doesn’t contain real gold. Or, it could contain a mixture of real and fake materials, like fake gold but real silver. By damaging the fake gold, you’ve now lowered the overall value of the item. The seller is not going to be happy and you’ll likely have to purchase the item or compensate them for the damage.

Thankfully, XRF is non-destructive. The part of the sample that is excited by the X-ray is so minuscule that it can’t be seen by the naked eye. This means you can confidently test any kind of sample without fear of damage. 

The second issue is that acid testing isn’t as accurate as XRF. While it can tell you if gold is real or fake, true success in the precious metal industry comes from knowing the exact quantity and quality of the precious metals you buy and sell.

XRF tells you the precise composition of the sample, empowering you to be confident in your transactions. 

Saves Your Time

XRF isn’t just the most accurate precious metal testing method – it’s also the fastest!

Acid testing requires you to scratch the surface of the sample and then carefully administer the acid. Because the acid is corrosive, you also need to wear protective gear and be in a controlled environment.

With XRF, the X-ray excites the sample in just seconds, giving you an extremely quick reading. The sample doesn’t need to be prepared, and you don’t have to take any precautions. Simply use your XRF device and get precise analysis on the spot. 

It’s also worth mentioning that other testing methods like acid require you to go out and purchase testing kits. That’s an incredibly inefficient system if you are testing large quantities of precious metals on a daily basis. With XRF, you only need one device and it will last you for years. 

Saves Your Reputation

Fast and accurate testing obviously increases your capacity to trade and the money you can make through trading, but there is also something else they improve – your reputation!

As technology improves, the industry expects you to improve with it. If you’re still using precious metal testing methods that require identification through sight, touch or torches, the commodities you sell are soon going to be scrutinised by people who are using XRF. 

Buyers will become increasingly wary (if they aren’t already) of traders who don’t use advanced testing methods. If they are using XRF and you aren’t, the discrepancies between their analysis and yours will become too glaring to ignore. 

The Niton XL2 Precious Metal Analyser

The Phenotyping Phenomenon: How Plant Phenotyping Technology Improves Plant Performance

The Phenotyping Phenomenon: How Plant Phenotyping Technology Improves Plant Performance

For much of history, people prayed to their gods to deliver them a good harvest. There’s no need to pray anymore…

With the help of plant phenotyping technology, you can control almost every aspect of your crop growth, making you more confident in your yields.

Read on to learn more about what plant phenotyping is and how it can improve your plant performance. 

What is Plant Phenotyping?

Plant phenotyping is the study of a plant’s physical and physiological traits. By gathering this information, you can get a complete picture of a plant’s phenotype, which includes all its observable characteristics and helps you create the perfect conditions for optimum growth. 

The History of Plant Phenotyping

While people have been experimenting with plant phenotyping since the invention of agriculture, it first became a recognised discipline in the 19th century. Scientists, armed with Darwin’s theory of evolution, began studying plant anatomy and physiology to better understand their growth and development. 

In the early 20th century, plant breeding became more widespread. Advancements in smart digital farming have made plant phenotyping a rapidly advancing science in recent decades.

How Does Plant Phenotyping Work?

Plant phenotyping measures and analyses various physical plant traits, such as their: 

  • Height
  • Biomass
  • Root length
  • Leaf size and shape
  • Flower colour

This list is by no means exhaustive, and will differ depending on the plant species. For example, some plants may not have roots, while some may not have flowers. 

It isn’t just the physical characteristics that are assessed. The plant’s physiological characteristics are also important. These can include:

  • The presence of parasites or mould growth
  • Photosynthesis 
  • Transpiration
  • Water use efficiency
  • Susceptibility to climate and temperature

Once again, there may be many more characteristics analysed depending on the specific species. This information tells you what’s going on beneath the surface, especially when considering how the environment impacts growth and yield. 

Finally, the data collected from both physical and physiological measurements is analysed to get meaningful insights into the plant’s phenotype. These insights can be used to understand the genetic and environmental factors that impact plant growth and development, and make informed decisions about breeding programs and crop management.

The Benefits of Plant Phenotyping

There are many benefits to integrating plant phenotyping into your crop management plan.

Improved Plant Survivability and Yield

Plant phenotyping helps identify the genetic and environmental factors that affect the viability of your crops. By identifying the risk factors that cause plants to die or under-produce, you can perfect your growing conditions, leading to improved yields and plant health.

Improved Understanding of Ideal Environment

Plant phenotyping can help you understand how plants respond to various environmental stressors, such as drought, heat, and salinity. This information can be used to develop more resilient crops that can better withstand these factors..

Better Breeding Selections

Information from plant phenotyping can help breeders select the best plants for breeding. Desirable traits can include:

  • Survivability
  • Interesting or unique traits
  • Natural disease resistance
  • Climate hardiness
  • Optimal yield 

This helps you eliminate undesirable genes and diseased plants from your crop, or helps you breed a hardier crop over time. 

How Has Technology Impacted Plant Phenotyping?

Plant phenotyping previously needed to be done by hand, but advancements in image processing and simulating environmental conditions has made phenotyping less labour intensive and more scalable. One tool that can do both is the LemnaTec PhenoTron.
