Temporal Stability of Soil Microbial Properties in Responses to Long-Term Application of Compost Obtained from Tannery Sludge

Successive applications of compost obtained from tannery sludge affected the soil microbial biomass and activity. However, effect this practice on temporal stability properties is not known. This study evaluated biomass, respiration, enzymes activities in with successive sludge. Soil samples (0–10 cm depth) were collected sites application at lowest (2.5 ton/ha) highest (20 rates, including control (0 ton/ha). carbon (MBC) nitrogen (MBN), dehydrogenase, urease 0, 30-, 60-, 90-, 150-days post-application. The varied as per treatments sampling time. principal response curve showed higher variation treatment having rate compost. analysis urease, MBC most responsive parameters. parameters values that contributed to a decrease increase rate.
