Description Not Available
Comprehensive reports on land-use changes and their
impact on soil biological properties, specifically
microbial population in the Indo-Gangetic Plains
(IGP) of India, are lacking. Since IGP is the most
fertile land, data on microbial population of IGP
may contribute towards the evaluation of various soil
quality parameters, disease suppression, organic
matter decomposition, plant growth promotion and
soil management pattern. To enhance our knowledge
on culturable microbial populations in different soil
horizons of the agro-ecological sub-regions (AESRs) in
the IGP, a study has been undertaken to collect soil
samples from the established benchmark (BM) spots
of these plains with an objective to investigate the
impacts of bioclimates, soil depth, cropping systems,
land use systems and management practices on the
distribution of culturable microbial population.
Bacterial : fungal ratios are significantly different
across the land use types. The bacterial and fungal
populations are strongly and negatively correlated
with soil depth and maximum microbial population
(40%) exists in the surface horizon (0–30 cm) than
in the subsurface horizon (121–150 cm). Generally,
bacterial populations are higher than actinomycetes
and fungal populations in all soil profiles of the
IGP. Approximately 10% decrease in Shannon diversity
index has been observed with increase of 30 cm
depth and 89% fall between surface and subsurface
profiles. Non-significant difference in microbial population
(P < 0.05) is noticed across the management and
land use systems. Sub-humid (moist) bioclimatic
system recorded higher microbial population
than sub-humid (dry) and semi-arid bioclimatic
systems. Legume-based cropping system has higher
microbial population than cereal or vegetable-based
cropping.
