Relation of Microbial Population Dynamics and Nutrient in Soil of Continuous Cropping with Peanut

This paper analyzed the microbial populations and nutrients in soil of continuous cropping with peanut. The results showed that with the increase in years of continuous cropping, fungi quantity increase, the number of bacteria count decreased obviously, and the R/S of microbe in soil of rhizosphere and bulk reduced. The hydrolysable N, as measured after one year of continuous cropping, exhibited a significant change. The contents of rapidly available K and P in soil, was found significantly positively related to the number of bacteria.
