The land resource inventory of Yadgir-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 725 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 84
per cent in the microwatershed is covered by soils and about 1 per cent by quarry, about
15 per cent rock outcrop and others (Habitation and water bodies). The salient findings
from the land resource inventory are summarized briefly below.
 The soils belong to 16 soil series and 19 soil phases (management units) and 10 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 is suitable for agriculture in the microwatershed.
 About 9 per cent area of the microwatershed has soils that are very shallow (150 cm) soils in the microwatershed.
 About 27 per cent are sandy soils, 18 per cent soils are loamy and 40 per cent are
clayey soils at the surface.
 About 72 per cent is non-gravelly (
