Continuous cereal crops can be costly, model reveals

Plain text source: 
LUSO was developed by Dr Lawes and Dr Michael Renton of The University of Western Australia's (UWA) School of Plant Biology under a Grains Research and Development Corporation (GRDC) funded project also involving the Department of Agriculture and Food (DAFWA)... Dr Lawes said LUSO showed that yield losses of at least 10 to 20 per cent were commonly incurred when two consecutive cereal crops were grown, with additional losses from three or more consecutive cereals... "When prices for wheat are really high, it may be more profitable in the short-term not to grow a break crop, but you will produce nowhere near the potential yields and there may be long-term ramifications from growing consecutive cereals."..
