Stubble grazing sustains soil quality and carbon in wheat crop drylands

Stubble grazing is traditionally perceived as a practice that degrades soils. As potential consequence is the decrease of soil carbon, which is transferred to the atmosphere as CO2, a greenhouse gas. To check this assumption scientists Stavi et al. studied stubble grazing following wheat crops in drylands. They found that moderate stubble grazing does not degrade the soil and does not decrease the quantity of soil organic carbon.
