Report


This project aimed to evaluate the effect of summer fallow management on soil water storage. A combination of field experimentation and simulation analysis was used to quantify the effects of different management practices and to explore management strategies. Control of weeds had the greatest impact on soil water storage during the fallow (11 mm on average). In autumn and winter residue retention past May 1st was effective in conserving moisture (average 9-25 mm depending on residue levels). The findings have been communicated to growers and advisers. Fallow management strategies have been developed that benefit the crop in drier years and reduce the risk of deep drainage in wetter years.
