Interaction of soil pH and sulfonylurea herbicide degradation on legume growth

Research output: Book chapter/Published conference paperConference paperpeer-review


Take home messages
Degradation of triasulfuron and chlorsulfuron decreases as soil pH approaches a neutral pH.
Liming acidic soils can increase lupin growth and nodulation.
Soils approaching a neutral soil pH due to ‘overliming’ can reduce lupin growth and nodulation.
Sulfonylurea (SU) herbicides applied to soils with pH stratification may result in poor legume growth due to the impact of herbicide residue in the surface few centimetres and the soil acidity in subsurface layers.
