New Laser Tool Transforms Soil Carbon Analysis

A groundbreaking innovation in soil carbon analysis could change the evaluation of carbon in soil.  A collaboration between researchers and industry experts has led to the development of an advanced tool that measures soil carbon content efficiently and cost-effectively.  

Soil plays a vital role in capturing and storing carbon from the atmosphere, a process known as carbon sequestration. Agricultural practices can either deplete or enhance soil organic carbon levels, impacting both environmental sustainability and crop productivity.  

Monitoring these levels accurately is crucial for advancing regenerative farming techniques that contribute to net-zero goals. 

Traditional soil testing methods require multiple steps and the use of chemical reagents, making the process costly and time-consuming. To address these challenges, a new approach utilizing laser-induced breakdown spectroscopy (LIBS) has been introduced. Originally designed for mining applications, LIBS technology has now been adapted for large-scale soil carbon measurement, offering rapid, precise, and chemical-free analysis. It was developed by NRC and Canadian agri-environmental firm Logiag. 

This next-generation tool, developed through extensive research and collaboration, simplifies soil testing. Unlike conventional methods, LIBS technology reduces analysis time from days to minutes while significantly lowering costs. It requires no chemical processing, making it an environmentally friendly alternative to traditional techniques. 

The newly developed system can process significantly more samples than previous methods, making it highly efficient for large-scale agricultural projects. With its proven accuracy and cost-effectiveness, this innovation is gaining traction in commercial laboratories across different regions. 

With global efforts focused on achieving net-zero emissions, accurate carbon measurement tools are essential for monitoring progress. This collaboration highlights the potential of technological advancements in supporting climate action and sustainable agriculture.  

By enhancing carbon sequestration monitoring, this innovation contributes to global sustainability goals and showcases advancements in soil science. 

This development marks a significant step forward in agricultural research, ensuring that farmers and policymakers have the necessary tools to make informed decisions that benefit both productivity and the environment.

Paul Mann, CEO of Wahupta Industries, tell us about SmartSoil. SmartSoil®, is an organic and proprietary metabolite-rich liquid that is produced from the cultivation of microalgae.

Third party research has produced yield increases from 15 to 39 percent. Other observed and documented benefits include,

~ Enriched nutrient and water uptake
~ Enhanced plant and root growth
~ Increased microbial growth associated with healthier crops
~ Increased environmental stress tolerance

SmartSoil contains certain metabolites which stimulate the natural microbial activity in the soil. The increase in beneficial microorganisms leads to improved soil quality and better nutrient uptake by the plant.
SmartSoil works as a signaler between crops and soil microbes improving nutrient uptake in crops.
