Derived from a wide range of rocks and minerals, a
large variety of soils occur in the Indian subcontinent.
Soil-forming factors like climate, vegetation and
topography acting for varying periods on a range of
rock formations and parent materials, have given rise
to different kinds of soil. The National Bureau of Soil
Survey and Land Use Planning, Nagpur has developed
a database on soils with field and laboratory studies
over the last 30 years. This has generated maps and
soil information at different scales, showing area and
distribution of various soil groups in different agroecological
subregions. The 1 : 250,000 scale map shows
a threshold soil variation index of 4–5 and 10–25 soil
families per m ha for alluvial plains and black soil
regions respectively. Progress in basic and fundamental
research in Indian soils has been reviewed in terms
of soils, their formation related to climate, relief,
organisms, parent materials and time.
