Soil Microbial Biomass and Microbial Quotient under Different Plantations at Maldeota, Dehradun, India
Abstract: Microbial properties have been reported to be useful indicators of soil quality and could serve as assessment criteria for the successful rehabilitation of ecologically disturbed areas. The microbial quotient – ratio of soil microbial biomass C to soil organic C – may, therefore, be a more sensitive parameter to monitor organic matter dynamics than either microbial biomass C or soil organic C considered alone. The study site is located at …
