Nutrition x Deep Ripping in pulses across multiple soil types locations
Aims

To evaluate the grain yield response of lentils and barley to deep ripping and nutrition (phosphorus and trace elements) across soil types commonly encountered in Mallee paddocks. 

Key messages
  • The yield benefit from deep ripping prior to sowing lentils was 0.1 – 0.2 t/ha (30 – 80%) on the sandy soil only. 
  • The yield benefit from deep ripping prior to sowing barley was 0.2 – 0.3 t/ha (30 – 40%). 
  • Negative responses to deep ripping were observed on the heavy soils. 
  • There was a yield response in both lentil and barley to the highest MAP rate on the clay loam soil. 
  • There was no grain yield response in lentil or barley to SOA or trace elements.
