The land resource inventory of Yadgir Rf-2 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, behavior and use potentials of the soils in the
microwatershed.
The present study covers an area of 385 ha in Yadgir taluk & district, Karnataka.
The climate is semiarid and categorized as drought-prone with an average annual
rainfall of 866 mm, of which about 652 mm is received during south-west monsoon, 138
mm during north-east and the remaining 76 mm during the rest of the year. An area of
264 ha in the microwatershed is covered by soils, 116 ha by rock outcrops and 5 ha by
others (habitation and water body). The salient findings from the land resource inventory
are summarized briefly below.
 The soils belong to 6 soil series and 8 soil phases (management units) and 5 land
management units.
 The length of crop growing period is about 120-150 days starting from 1st week of
June to 4th 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 320 m grid interval.
 Land suitability for growing 29 major agricultural and horticultural crops was
assessed and maps showing the degree of suitability along with constraints were
generated.
 Entire area in the microwatershed is suitable for agriculture.
 About 39 per cent area is very shallow (150 cm).
 About 48 per cent area in the microwatershed has sandy soils, 11 per cent loamy
soils and 9 per cent soil clayey at the surface.
 An area of 51 per cent in the microwatershed is gravelly (15-35%) and 18 per
cent area is non gravelly (200 mm/m) in
available water capacity, 9 per cent is medium (101-150 mm/m) and 58 per cent is
very low (
