The land resource inventory of Bidarched 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 the 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 and use potentials of the soils in the microwatershed.
The present study covers an area of 547 ha in Sedam taluk of Gulbarga district,
Karnataka. The climate is semiarid and categorized as drought-prone with an average
annual rainfall of 839 mm, of which about 639 mm is received during south-west
monsoon, 109 mm during north-east and the remaining 91 mm during the rest of the year.
An area of 513 ha (94%) in the microwatershed is covered by soils and about 35 ha by
others (habitation and water bodies). The salient findings from the land resource
inventory are summarized briefly below.
 The soils belong to 3 soil series and 8 soil phases (management units) and 2 land
use class
 The length of crop growing period is about 120-150 days starting from 2nd week
of June to 3rd week of October.
 From the master soil map, several interpretative and thematic maps like land
capability, soil depth, surface soil texture, soil gravelliness, available water
capacity, soil slope and soil erosion were generated.
 Soil fertility status maps for macro and micronutrients were generated based on
the surface soil samples collected at every 250 m grid interval.
 Land suitability for growing 19 major agricultural and horticultural crops was
assessed and maps showing the degree of suitability along with constraints were
generated.
 About 94 percent of area in the microwatershed is suitable for agriculture
 About 84 per cent area of the microwatershed has soils that are deep (100-150
cm) to very deep (>150 cm) and 10 per cent soils are shallow (25-50 cm) in
depth.
 About 94 per cent area of the microwatershed has clayey soils at the surface
 About 70 per cent area is non gravelly (200 mm/m) in
available water capacity and 10 per cent area is low (51-100 mm/m) in available
water capacity
 About 84 per cent area of the microwatershed has very gently sloping (1-3%
slope) lands and 10 per cent area is gently (3-5% slope) sloping lands
 An area of about 10 per cent has soils that are slightly eroded (e1) and 84 per
cent area is moderately (e2) erode
 An area of about 94 per cent soils are moderately (pH 7.8-8.4) to strongly
alkaline (pH 8.4-9.0)in soil reaction
 The Electrical Conductivity (EC) of the soils in 17 per cent area is
