The land resource inventory of Halhalli 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 734 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 about 95 per cent is covered by soils, three per cent by rock-out crops and two
per cent by water bodies, settlements and others. The salient findings from the land
resource inventory are summarized briefly below.
 The soils belong to 15 soil series and 31 soil phases (management units) and 8 land
use classes.
 The length of crop growing period is 150 cm).
 About 5 per cent of the area is having sandy soils, 54 per cent loamy soils and 36 per
cent has clayey soils at the surface.
 About 46 per cent of the area has non-gravelly (9.0) in reaction.
 The Electrical Conductivity (EC) of the soils are dominantly
