Effect of different organic nutrient sources on soil ecosystem as well as enzymatic activities were studied in a subtemperate
hilly agro-ecosystem in India. At crop harvest, soil enzymatic activities and physico-chemical properties of soil were
analyzed after cultivating for two consecutive years along with its residual effects. Comparing with control treatment, addition
of poultry manure (PM), farm yard manure (FM) and vermicompost (VC) increased SOC by 35%, 57% and 53%, respectively, at
recommended dose of application. Dehydrogenase activity was higher in the FM treatments by 40-198% followed by 20-102%
in VC treatments, 10-60% in PM than in control. Protease and cellulase activity increased in all the treatments significantly
except control. �-glucosidase activity was higher in PM treatment and was at par with highest rate of application. Alkaline
phosphatase and urease activity was more influenced by application of FM compared with VC and PM. Activity of hydrolase
enzymes was different in PM, FM and VC treatments. Phosphatase activity was increased and is attributed to microbial
stimulation by organic C and soil pH. Differences in all enzymatic activities were narrowed down in residual treatments
compared with control having little change in the trend in tomato-garden pea cropping system. This finding is more important
for hilly regions because of variable soil depth, pH, moisture and fertility status. As our general recommendation of organic
nutrient is mostly based on N requirement of crops, it is better to supply through FYM for better soil health and biological
properties.
