Microorganisms play a critical role in nutrient transformation, soil health and for sustaining
the productivity of soils. Effects of long-term cropping, fertilization, manuring and their
integration on microbial community were studied in soil samples from five long-term
fertilizer experiments under various rainfed production systems in the semi-arid tropics
(SAT) of India. Microbial population counts were analyzed by dilution plating and were in
turn compared with different parameters such as soil treatments, soil type, soil microbial
biomass C, soil organic C, rainfall and soil pH. The counts were high in treatments where
combinations of organic and inorganic fertilizers were applied compared to control. Vertisols
showed larger organic carbon levels than Alfisols. Fungal population was higher in
acidic soils and in treatments under continuous inorganic fertilization treatments whereas
a high number of bacteria were found in integrated use of organic and inorganic fertilizers.
At most of the locations soil organic C and microbial biomass C showed significant positive
( p 0.05) correlation with microbial populations. Thus, results suggest that even under arid
and semi-arid tropical conditions, regular addition of nutrients in an integrated manner
could improve soil organic carbon and microbial population counts. For each production
system, better carbon sequestration management practices were identified.
