The land resource inventory of Kyatanal 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
microwatersheds.
The present study covers an area of 551 ha in Kyatanal microwatershed in Yadgir
taluk and 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 about 93 per cent is covered by soils, 7 per cent by rock outcrops
habitation and water bodies. The salient findings from the land resource inventory are
summarized briefly below.
 The soils belong to 9 soil series and 18 soil phases (management units) and 5 land
use classes.
 The length of crop growing period is 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 320 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.
 About 3 per cent soils are shallow (25-50 cm), 43 per cent soils are moderately
shallow (50-75 cm), 21 per cent are moderately deep (75-100 cm) and about 25
per cent soils are deep (100-150 cm) to very deep (>150 cm) soils.
 About 56 per cent of the area has clayey soils, 29 per cent loamy soils and 7 per
cent sandy soils at the surface.
 An area of about 81 per cent has non-gravelly and 11 per cent are gravelly soils.
 About 25 per cent of the area has soils that are very high (>200 mm/m) in
available water capacity, 53 per cent medium (101-150 mm/m), 12 per cent low
(51-100 mm/m) and about 3 per cent very low (9.0)
in soil reaction.
 The Electrical Conductivity (EC) of the soils are dominantly is
