摘要: Abstract The present study conducted in the Nokrek biosphere reserve (BR) of Meghalaya north-east India aimed at analyzing impact human activities such as shifting agriculture (‘Jhum’) and horticultural practices on temporal spatial changes microbial biomass dehydrogenase urease soil. Microbial biomass-C (MBC) -N(MBN) well were significantly (P
