Research progress on effects of straw incorporation on soil micro-ecological environment

Abstract:

Straw is one of the most abundant biomass resources in the world. As the main utilization way of straw, straw incorporation is associated with the sustainable development of agriculture. Microorganisms are the most active bio-factors in the soil ecosystem, which are closely related to straw degradation, nutrient circulation, and soil health. To understand the micro-ecological effects of straw incorporation, we analyzed the soil enzyme activity, microbial biomass, culturable microbial populations, and diversity after straw incorporation. Furthermore, we compared the soil micro-ecological indicators under different conditions of straw incorporation, and discussed the limitations of the related studies. Finally, we put forward an outlook on the future research directions in this field. This study can provide a basis for safe straw incorporation.
