Abstract

Compared with traditional tillage, the farmland soil ecosystem realizes increase in the number and diversity of soil microorganisms and animal communities. The conservation tillage measures such as no-tillage (zero tillage) and covering the farmland with organic matters reduce the disturbance to the soil, increase the accumulation of soil organic matter, and provide an excellent microhabitat for the biological activity of the soil. Soil organisms are closely related to soil nutrient movement. Soil animals, soil microorganisms and soil enzymes secreted by them are widely involved in the conversion process of organic matters and mineral nutrients, and they also play an important role in the effectiveness of nutrient utilization. Studies have shown that long-term conservation tillage is favorable for improving the soil biological activity, improving the soil health, and increasing the fertilizer utilization efficiency and the conservation in soil.
