Study on Soil Evaporation of No-tillage with Mulch

We analyzed soil evaporation of different tillage treatments. Although water consumption difference was not significant among the tillage treatments, soil evaporation changed significantly. Compared with conventional tillage and direct drilling, no tillage could reduce soil evaporation effectively. The lowest daily soil evaporation was in no tillage while conventional tillage was the highest. The proportion of evaporation to evaportransportation for conventional tillage was the highest and no tillage the lowest. No tillage with mulch could reduce soil evaporation and increase crop transportation, which was important for water saving agriculture.
