Description :
Analysis from 8 wind events show that significant relations exist between total mass of soil in both horizontal (saltation) and vertical (suspension) transport. The data suggest that by limiting horizontal soil erosion, emitted dust can be simultaneously reduced. Aggressive conservation tillage can be effective weapon in reducing soil erosion by maintaining surface residue and roughness.
