Description of practice
Subsoiling is a tillage practice that loosens the subsoil with minimum disturbance of the topsoil. It is primarily used to control plough pans.
|Examples of how to use subsoiling
(see Note below)
Subsoiling with mulching
A subsoil plough is used to loosen subsoils while leaving the surface soil undisturbed. A stubble mulch is kept on the soil surface.
No tillage preceded by subsoiling
A subsoiler at a 50 cm depth is used every 5 years in combination no tillage cultivation.
A decompactor is a large subsoiler implement that lifts the soil at a depth of 30-40 cm by 5 cm and moves it sideways; hardpan soil layers are broken so that the permeability and structure of the soil is greatly improved.
