The land resource inventory of Kalagatahundi-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 and use potentials of the soils in the microwatershed.
The present study covers an area of 306 ha in Gundlupet taluk of
Chamarajanagar district, Karnataka. The climate is semiarid and categorized as
drought-prone with an average annual rainfall of 734 mm of which about 254 mm is
received during south–west monsoon, 268 mm during north-east and the remaining 212
mm during the rest of the year. An area of about 84 per cent is covered by soils, sixteen
per cent by forests and others. The salient findings from the land resource inventory are
summarized briefly below.
 The soils belong to 7 soil series and 15 soil phases (management units) and 6 land
management units.
 The length of crop growing period is about 150 days starting from the 3rd week of
June to 3rd week of November.
 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 major agricultural and horticultural crops were
assessed and maps showing the degree of suitability along with constraints were
generated.
 Entire area of the microwatershed is suitable for agriculture.
 About 49 per cent of the soils are moderately deep (75-100 cm) to very deep (>150
cm) and 35 per cent are shallow to moderately shallow (25-75 cm).
 About 40 per cent of the area has clayey soils at the surface, 38 per cent loamy soils
and 6 per cent area has sandy soils.
 About 59 per cent of the area has non-gravelly soils and 25 per cent gravelly (15-35
% gravel) soils.
 About 47 per cent has soils that are very low (200 mm/m)
available water capacity.
 About 67 per cent of the area has very gently sloping (1-3% slope) lands and 17 per
cent is under gently sloping (3-5%) lands.
 An area of about 56 per cent has soils that are slightly eroded (e1), 23 per cent
moderately eroded (e2) and 5 per cent soils are severely eroded (e3).
 An area of about 17 per cent has soils that are slightly acidic (pH 6.0-6.5); 12 % are
moderately acid (pH 5.5-6.0), 43 per cent area has neutral (pH 6.5-7.3) and
maximum area of about 12 per cent has soils that are slightly alkaline (pH 7.3 to 7.8)
to moderately alkaline (pH 7.8 to 8.4).
 The Electrical Conductivity (EC) of the soils are dominantly
