A long-term study to increase water use efficiency, grain yield and the profit of growers in the Western region in a no-till system. Mingenew Site.

The main principles of conservation agriculture are permanent soil cover, minimal soil disturbance and diverse crop rotations, yet these are often absent from our no-till systems. This project was designed to test and further develop high quality no-till systems based on these conservation principles. The project commenced in 2006 and completed twelve years of cropping in 2018. An additional year was completed in 2019 with the whole trial seeded to wheat. The overall objective of the project was to determine the benefits of diverse rotations, high residue and minimal disturbance no-till systems on soil quality, weeds, diseases as well as crop water use efficiency, economics, and yield.
