No-Tillage Sowing Decreases Water Erosion On Loamy Soils And Increases Earthworm Activity, Kevin Bligh
No-Tillage Sowing Decreases Water Erosion On Loamy Soils And Increases Earthworm Activity, Kevin Bligh
Journal of the Department of Agriculture, Western Australia, Series 4
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.

Much wheatbelt agriculture is based on thin topsoils which are inherently infertile by world standards. Erosion even to the depth of cultivation will cause the loss of:—
• most of the original topsoil
• the phosphate build up from years of "super" applications
• any accumulation of organic matter and humus.
