No-till is sowing a crop without prior cultivation and with very little soil disturbance at seeding. There are several terms that have evolved in WA agriculture. The main tillage terms from most to least cultivation are:

• multiple tillage (previously known as conventional tillage);
• reduced tillage which is one pass prior to seeding with a full cut-out;
• direct drilling which is one pass seeding with a full-cut;
• no-till which is narrow/knife point seeding with less than full cut-out;
• zero-till which is disc seeding.

The term

minimum tillage

is confusing as it can mean all of these things except multiple tillage and therefore it should be dropped.
