Groundbreaking technique could help avoid famine and drought by assessing soil health
Scientists have harnessed the power of seismology, a technology typically used for measuring earthquakes, to create a novel method for assessing soil health. This breakthrough technique, dubbed "soilsmology," uses seismic waves generated by striking a metal object with a hammer to map the structure of the soil beneath the surface.
By analyzing the way these waves travel through the soil, researchers can gain insights into its composition, moisture levels, and microbial activity. This information can be used to identify areas that require additional water or organic matter, allowing farmers to optimize crop yields and reduce waste.
The Earth Rover programme, a non-profit initiative co-founded by Guardian columnist George Monbiot, aims to create a free app for farmers to monitor their soil's health and receive advice on how to improve it. The project's soil ecologist, Prof Simon Jeffery, notes that "soil is one of our most precious resources" and that the current methods used to assess its health are often time-consuming and damaging.
Poor agricultural practices, such as intensive tillage and pesticide use, have led to widespread soil degradation worldwide. As a result, global crop yields are expected to decline by 50% in some regions due to increased population pressures.
The new technique has been tested in Kenya, where it has shown promise in detecting subsoil compaction and reducing flood risk. Soil scientist Peter Mosongo believes that this technology could be "life-changing" for farmers in the region, enabling them to take targeted interventions to improve soil fertility and address food security concerns.
While more research is needed, the potential of soilsmology as a tool for predicting soil properties and optimizing crop yields is undeniable. As Aidan Keith, a soil ecologist at the UK Centre for Ecology and Hydrology, noted, "the development of advanced sensor technology and robust data analysis to predict key soil physical properties using seismic waves could be transformative."
