Effects of artificial humic acid on decomposition of returning straw and enhancement of carbon sequestration
Straw returning is one of the commonly used comprehensive utilization methods of straw, but the slow decomposition of straw could affect crop growth. Artificial humic acid (A-HA) can improve the physical and chemical properties of soil and facilitate the growth of soil microorganisms. In a 180-day incubation experiment, A-HA was used as a propulsive activator to study its effects on decomposition, soil carbon fixation and emission reduction of returning straw. The results showed that the decomposition rate of straw increased by 31 % in the presence of artificial humic acid after 180 days. Moreover, A-HA increases the diversity and abundance of soil microorganisms, especially those associated with carbon sequestration, thereby reducing the rate of CO2 emissions. This study improves insights on the application of artificial humic acid in promoting straw decomposition, soil carbon sequestration and emission reduction.
期刊介绍：
Applied Soil Ecology addresses the role of soil organisms and their interactions in relation to: sustainability and productivity, nutrient cycling and other soil processes, the maintenance of soil functions, the impact of human activities on soil ecosystems and bio(techno)logical control of soil-inhabiting pests, diseases and weeds.
