How Stubble Affects Organic Matter, Plants And Animals In The Soil, Judy Tisdall

Journal of the Department of Agriculture, Western Australia, Series 4

Cereal yields have not increased greatly in Australia over the past 30 years and they are still only about half the potential determined by rainfall. One of the reasons for these low yields is our fragile soils, worsened by traditional systems of tillage and the burning of stubble. These systems reduce the levels of organic matter and biological activity in soil

Few farmers would question the desirability of retaining stubbles, both for control of erosion by wind and water, and to return organic matter to the soil. While the present debate is focused on the short term management of stubbles, longer term effects also need to be considered.

The Department of Agriculture has several long-running trials intended to measure long term effects.
