Definitions of no-till
-
multiple tillage – two or more tillages before seeding (this replaces the term ‘conventional tillage’)…
-
reduced tillage – one pass of full soil disturbance prior to seeding…
-
direct drilling – one pass seeding with a full-cut or greater than 20% topsoil disturbance…
-
no-tillage – knife point or disc seeding with 5–20% topsoil disturbance; and…
-
zero-tillage – disc seeding without soil throw (but note that some discs do throw soil).
Globally, Conservation Agriculture is defined as Zero Till – full residue retention, diverse crop rotations and minimal as possible soil disturbance.
Bill endorses this definition, however, diverse crop rotations are a real challenge in the very dryland farming areas of Western Australia.
