Early Sowing, Legumes and Long- Term Fertility

In this episode of MSF Farm Talk, we kick off a new series inspired by the book 101 Questions about SA Cropping Soils. Host Nick Paltridge is joined by Dr. Nigel Wilhelm from the South Australian Research and Development Institute to explore how cropping systems have evolved over recent decades—especially in low rainfall environments. The discussion covers key topics such as early sowing practices, nitrogen and phosphorus management during dry seasons, and the expanding role of grain legumes in sustainable crop rotations. Dr. Wilhelm also shares his perspective on the future of farming, highlighting the importance of diversified weed and pest control strategies for long-term productivity. This practical and forward-looking episode offers valuable insights for farmers, agronomists, and anyone involved in dryland agriculture.
