Sheep grazing on crop residues increase soil mineral N and grain N uptake in subsequent wheat crops locations
Aims

To determine the impact of sheep grazing on stubbles during the summer fallow period on soil properties, crop resources and growth under no-till, controlled traffic cropping with strict weed control.

Key messages
  • Grazing crop stubbles makes more mineral N available to crops which increases grain N uptake and is perhaps an overlooked benefit of keeping livestock in stubble-retained farming systems.
