To investigate water repellence mitigation options at seeding. The trial aims to identify the driving chemistries (surfactants vs humectants) and application techniques (furrow surface, vs seed zone) that are better able to lift crop responses under local sowing conditions. This article reports on the Year 1 data, with more work being planned for the 2019-20 seasons.
