Deep ploughing to control soil pests
Deep ploughing of the soil can be a way to kill certain types of pests which live in the soil
© FAO/Giulio Napolitano
Deep ploughing has been recommended as a strategy to kill insect pests that live in the top 20 cm of soil. By exposing the larvae or pupa to sunlight, and by physical crushing in the ploughing process, pest numbers can be reduced. But the method may also have adverse effects on soil health and structure, so farmers need expert advice for when to use it.
