The land resource inventory of Rampura-1 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 537 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
530 ha in the microwatershed is covered by soils, 1 ha by rock outcrops and about 7 ha
by others (water bodies). The salient findings from the land resource inventory are
summarized briefly below.
 The soils belong to 12 soil series and 24 soil phases (management units) and
5 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 250 m grid interval.
 Land suitability for growing 26 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 42 per cent area of the microwatershed has soils that are moderately
deep to very deep (75 - >150 cm) and 56 per cent soils are shallow to
moderately shallow (25-75 cm).
 About 43 per cent area in the microwatershed has loamy soils, 17 per cent
sandy and 39 per cent clayey soils at the surface.
 About 69 per cent area in the microwatershed is non gravelly (200 mm/m) in
available water capacity, 15 per cent is medium (101-150 mm/m), 46 per
cent area is low (51-100 mm/m) and 1 per cent area is very low (9.0)
 The Electrical Conductivity (EC) of the soils in the entire area of the
microwatershed is dominantly 57 kg/ha).
 About 88 per cent is medium (145-337 kg/ha) in available potassium and 10
per cent is high (>337 kg/ha).
 Available sulphur is low (4.5 ppm) in 97 per cent area and deficient in 2
per cent area of the microwatershed.
 Available manganese and copper are sufficient in all the soils of the
microwatershed.
 Available zinc is deficient (
