- Abstract
[Objectives] This study was conducted to investigate the effects of milk vetch {Astragalus sinicus) on soil nutrients and microorganisms in paddy fields after returning to the field. [Methods]Three treatments, no fertilization, single application of chemical fertilizers and milk vetch return combined with chemical fertilizers, were set up to determine soil nutrient contents and the quantity of microorganisms, respectively. [Results] The return of milk vetch combined with chemical fertilizers could significantly increase the contents of organic matter and total nitrogen in the paddy soil, while the contents of available potassium and available phosphorus decreased. Milk vetch return combined with chemical fertilizers could significantly increase the quantity of soil microorganisms in the paddy field. [Conclusions] The return of milk vetch can be used as a feasible measure to improve soil fertility.
