Water balance of conservation farming systems 4

Plain text source: 
Farmers throughout southern Australia continue to seek improved conservation farming strategies, including increased levels of residue retention, reduced soil disturbance, and greater rotation diversity... CSIRO has been monitoring changes in the water balance on the trial since then, and so far we have demonstrated that early crop termination (as part of a cover cropping practice) can increase the risk of dryland salinity under some situations... Increased levels of residue retention have had little impact on the water balance in the short term (6 years), and so farmers can adopt this practice confident that there will be no negative short-term environmental impact due to changes in the water balance...
