The land resource inventory of Huvinahalu microwatershed was conducted using
village cadastral maps and IRS satellite imagery on 1:7920 scale. The false colour
composites of IRS imagery were interpreted for physiography and these physiographic
delineations were used as base for mapping soils. The soils were studied in several
transects and a soil map was prepared with phases of soil series as mapping units.
Random checks were made all over the area outside the transects to confirm and validate
the soil map unit boundaries. The soil map shows the geographic distribution and extent,
characteristics, classification, behavior and use potentials of the soils in the
microwatershed.
The present study covers an area of 853 ha in Koppal taluk and district,
Karnataka. The climate is semiarid and categorized as drought - prone with an average
annual rainfall of 662 mm, of which about 424 mm is received during south–west
monsoon, 161 mm during north-east and the remaining 77 mm during the rest of the year.
An area of 95 per cent is covered by soils, 4 per cent by rock outcrops and 1 per
cent is by habitation and settlements. The salient findings from the land resource
inventory are summarized briefly below.
 The soils belong to 18 soil series and 44 soil phases (management units) and 8 Land
Management Units.
 The length of crop growing period is 150 cm).
 About 1 per cent area in the microwatershed has sandy soils, 26 per cent area in the
microwatershed has loamy soils and 68 per cent clayey soils at the surface.
 About 47 per cent area has non-gravelly (
