Abstract
Changes in microbial C, N, and P were investigated for 1 year in two s oils with similar physicochemical properties but supporting different crops under subtropical conditions. One was cropped with palmarosa (Cy mbopogon martinii L.) and the other with Japanese mint (Mentha arvensi s L.). Both the season and the type of cropping had a significant infl uence on changes in the soil microbial biomass. In general, soil micro bial biomass C, N, and P were highest in summer months and lowest in m idwinter. Soil microbial biomass levels and microbial C:N and C:P rati os were higher and N:P ratios lower under palmarosa soil than under mi nt.
