Mechanical and ecological tillage pattern improving soil quality and crop yields

Tillage was the key factor affecting soil quality, and plowing, rotary tillage and sub-soiling etc. were the important links of tillage pattern. Years of plowing, trying to make the soil crushing and creating a good growth environment were the essence of traditional farming in China. In order to study the effects of different patterns on soil and yield, the soils of 0-10, > 10-20, > 20-30 cm layer were collected and tested for soil organic content, moisture content and bulk density, and yields of wheat and corn were recorded as well every year in the period for all treatments. Then the results were compared. The yields of Treatment W and N were significantly higher than Treatment F, and the order from the highest to the lowest was Treatment W, Treatment N and Treatment F; the difference was most significant in 2014, wheat yields of Treatment W was 30.8% higher than Treatment F and 22.5% than Treatment N, and yields of corn was 28.4% higher than Treatment F and 20.9% than Treatment N.
