The land resource inventory of Kondapur 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 352 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
331 ha (94%) in the microwatershed is covered by soils and 20 ha (6%) 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 5 soil phases (management units) and
one land use class.
 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 45 per cent area of the microwatershed has soils that are very deep
(>150 cm), 13 per cent soils are deep (100-150 cm) and 36 per cent soils
are moderately deep (75-100 cm).
 About 23 per cent area in the microwatershed has loamy soils and 71 per
cent clayey soils.
 Entire area of the microwatershed has non gravelly (200 mm/m) in available water capacity.
 An area of about 10 per cent has nearly level (0-1%) and 84 per cent has
very gently sloping (1-3% slope) lands in the microwatershed.
 An area of about 10 per cent are slightly eroded (e1), 68 per cent are
moderately (e2) eroded and 16 per cent area is severely (e3) eroded.
 An area of about 13 per cent is moderately alkaline (pH 7.8-8.4), 69 per
cent is strongly alkaline (pH 8.4-9.0) and 12 per cent is very strongly
alkaline (pH >9.0) in relation.
 The Electrical Conductivity (EC) of the soils in the entire area of the
microwatershed is 337
kg/ha) in available potassium.
 Available sulphur is low (
