Revolutionary Technique to Measure Soil Health and Boost Crop Yields
Scientists have made a groundbreaking breakthrough in soil health measurement by developing a novel technique using seismology, also known as "soilsmology". This innovative method involves hitting a metal piece on the soil with a hammer, measuring the waves that bounce back, and interpreting them to create a fine-grained map of what's happening underground.
Unlike traditional soil sampling methods, which involve digging numerous holes, this technique minimizes disturbance to the soil structure. The waves can be affected by factors such as soil dryness and microbial life, enabling farmers to detect issues and take targeted interventions to improve soil health.
According to Prof Simon Jeffery, one of the co-founders of the project, "Soil is one of our most precious resources. 99% of the calories we consume come from plants grown in soil. It's underappreciated by many people who don't realize its importance."
The current state of agricultural practice, including tilling and pesticide use, has severely degraded soil health worldwide, leading to crop yields forecasted to decline by 50% in some regions due to population growth. Farmers often rely on broad interventions such as fertilizing and tillage, which not only harms wildlife and pollutes rivers but also wastes resources.
The Earth Rover program aims to create a free app for farmers to measure soil health and receive personalized advice on improving it. By mapping the world's living soils, researchers hope to address soil fertility issues and mitigate the food crisis.
Using this seismic wave technology, scientists can detect areas of subsoil compaction, reducing flood risk and increasing crop yields. This breakthrough has significant implications for African farmers, where traditional soil maps are often based on limited samples, leading to unaddressed fertility problems.
The method also offers insights into soil carbon levels, currently estimated through guesswork. Experts emphasize the importance of protecting soils from erosion and degradation, as it can take centuries to develop 1cm of topsoil, which can be washed away in a matter of hours.
As Aidan Keith, a soil ecologist at the UK Centre for Ecology and Hydrology, noted, "Soilsmology has great potential as a method with limited disturbance and straightforward deployment. It could be transformative if combined with advanced sensor technology and robust data analysis."
