Interaction between soil water repellence and soil nutrient availability locations
Aims

To determine how soil inversion and banded surfactants change the availability of soil nutrients.

Key messages
  • The negative effect of water repellence management at this site is at odds with other work in this project. In both years we have observed a lower grain yield in the banded wetter, mouldboard ploughing and spading treatments than in the control at this site.
  • However, the average yield response to mouldboard ploughing and spading was 550 to 600 kg/ha over 28 sites.
  • For further details please see the attached trial report.
