The land resource inventory of Bandehalli-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 374 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
255 ha (68%) ha in the microwatershed is covered by soils, about 13 ha (3%) by rock
outcrops and about 106 ha (28%) by others (Habitation and water body). The salient
findings from the land resource inventory are summarized briefly below.
 The soils belong to 7 soil series and 9 soil phases (management units) and 5 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.
 An area of about 68 per cent is suitable for agriculture in the microwatershed.
 About 50 per cent area of the microwatershed has soils that are deep to very deep
(100- >150 cm), 5 per cent soils are moderately deep (75-100 cm), 13 per cent are
moderately shallow (50-75 cm) soils in the microwatershed.
 About 13 percent soils are loamy and 55 per cent is clayey soils at the surface.
 An area of about 57 per cent is non gravelly (200 mm/m) in
available water capacity. About 5 per cent area of the microwatershed is medium
(101-150 mm/m) and about 13 per cent soils are low (51-100 mm/m) in available
water capacity.
 An area of about 52 percent is very gently sloping (1-3% slope) lands and about 17
per cent soils are nearly level (0-1% slope) lands in the microwatershed.
 An area of about 52 per cent is moderately (e2) eroded and about 17 per cent are
slightly (e1) eroded lands in the microwatershed.
 An area of 17 per cent is neutral (pH 6.5-7.3), 29 per cent is slightly alkaline (pH
7.3-7.8) and 23 per cent is moderately alkaline (pH 7.8-8.4) in soil reaction.
 The Electrical Conductivity (EC) of the soils in the entire cultivated area of the
microwatershed is 0.75%) and about 13 percent is medium (0.50-
0.75%) in organic carbon content.
 An area of about 6 percent is low (57 kg/ha) in available phosphorus.
 An area of about 17 per cent is medium (145-337 kg/ha) and 51 per cent is high
(>337 kg/ha) in available potassium in the microwatershed.
 Available sulphur is high (>20 ppm) in an area of about 5 per cent, about 16 per
cent is medium (10-20 ppm) and about 47 per cent is low (
