Managing soil moisture

Moisture for germination and growth is critical to crop performance. Many different strategies exist to conserve soil moisture pre and post sowing, including spraying and tillage.

Online Farm Trials contains 150 trials covering issues that include: managing moisture variability within paddock; crop rotations that optimise moisture availability in the sequence; impacts of break crops and summer crops for production; and, future crop gains and interactions between soil moisture and nitrogen conservation, including timing of fertiliser application. There are 65 published trials for wheat, 16 for canola and 16 for barley linked to soil moisture conservation and use. There are also trials for lupins (6) and vetch (4).

For further information on soil moisture strategies, refer to the following case studies on low rainfall environments that consider summer weed control options to managing soil moisture:
