About this page

This page reports on a study by seismologists using acoustic soil monitoring that reveals excessive plowing has negative effects on soil. Researchers from the University of Washington and Chinese Academy of Sciences conducted experiments at an experimental farm in the UK using distributed acoustic sensing technology. They discovered that healthy soil contains a capillary-like structure that distributes water naturally. However, repeated deep plowing and soil compression from tractors damage this complex water distribution network, reducing water infiltration. Consequently, water accumulates near the surface where it easily evaporates. The research emphasizes that preserving natural soil structures is crucial for crop adaptation to increasingly harsh climate conditions.
