"To use more rainfall at the source, growers can work on improving crop agronomy, such as better management of water-repellent soils and soil nutrition," Mr Hall says "Another option is to improve the soil, which could mean alleviating soil compaction by the use of spading or other methods, or the use of clay spreading to improve water-holding and nutrient-holding capacities...
