No-tillage sowing places seed and fertiliser in the soil without loosening all of the topsoil. Soil is cultivated only in the sown rows, leaving the inter-row areas largely undisturbed.
No-tillage sowing reduces both wind and water erosion. Soil structure is generally improved, and pasture regeneration is increased because seed is not buried too deeply for re-establishment.
Two long-term trials were establis_hed on loamy soils to determine effects of tillage and cropping on runoff and soil loss.
"No-tillage sowing decreases water erosion on loamy soils and increases earthworm activity,"
