The land resource inventory of Sambar-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 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, behaviour and use potentials of the soils in the
microwatershed.
The present study covers an area of 530 ha in Sambar-2 microwatershed in
Yadgir taluk and district, Karnataka. The climate is semiarid and categorized as droughtprone
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 about 99 per cent is covered by soils and less than one per
cent by others (water body). The salient findings from the land resource inventory are
summarized briefly below.
 The soils belong to 10 soil series and 12 soil phases (management units) and
7 land management units.
 The length of crop growing period is about 120-150 days starting from the
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 250 m grid interval.
 Land suitability for growing 26 major agricultural and horticultural crops
were assessed and maps showing the degree of suitability along with
constraints were generated.
 Entire land area of the microwatershed is suitable for agriculture.
 An area of about 12 per cent soils are moderately shallow (50-75 cm), 15
per cent of the soils are moderately deep (75-100cm) and about 73 per cent
soils are deep (100-150cm) to very deep (>150 cm) soils.
 About 20 per cent of the area has clayey soils, 44 per cent loamy soils and
36 per cent sandy soils at the surface.
 An area of about 99 per cent has non-gravelly and 200mm/m) in
available water capacity, 50 per cent is medium (101-150 mm/m), 15 per
cent low (51-100mm/m) and about 5 per cent very low (
