Soil properties and microbial communities of spring maize filed in response to tillage with straw incorporation and nitrogen fertilization in northeast China.

ABSTRACT: Soil enzymes and microorganisms are both important to maintaining good soil quality and are also sensitive to changes in agricultural management. The individual effects of tillage, straw incorporation and nitrogen (N) fertilization on soil enzymes and microflora have been widely acknowledged, but their interactive effect remains largely unknown. In a 5-year in-situ field study, effects of rotary (RTS) and plow tillage (PTS) practices with straw incorporation combined with three N fertilization levels (0 kg N ha^-1, CK; 187 kg N ha^-1, MN; 337 kg N ha^-1, HN) on soil enzyme activities and microbial communities were assessed. Our results showed that the activities of β-glucosidase (βG), N-acetylglucosaminidase (NAG) and acid phosphatase (APH) were improved in RT
