The land resource inventory of Maddinahundi 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 450 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 the north-east and the remaining
212 mm during the rest of the year. An area of about 74 per cent is covered by soils, 21
per cent by forest and 5 per cent by others. The salient findings from the land resource
inventory are summarized briefly below.
 The soils belong to 10 soil series and 17 soil phases (management units) and 7 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.
 About 74 per cent area is suitable for agriculture.
 About 20 per cent of soils are shallow (25-50 cm), 6 per cent are moderately
shallow (50-75 cm), 13 per cent of the soils are moderately deep (75-100 cm), 7 per
cent of the soils are deep (100-150 cm) and 29 per cent are very deep (>150 cm).
 About 29 per cent of the area has clayey soils at the surface, 42 per cent area has
loamy soil and 3 per cent area sandy soils.
 About 37 per cent of the area has non-gravelly soils and 37 per cent gravelly (15-35
% gravel) soils.
 About 27 per cent has soils that are very low (200 mm/m) available water capacity.
 Entire area of about 74 per cent has very gently sloping (1-3% slope) lands.
 An area of about 45 per cent has soils that are slightly eroded (e1) and 29 per cent
soils are moderately eroded (e2).
 An area of about 2 ha (0.75%) in organic carbon.
 About 54 per cent of the soils are medium (23-57 kg/ha) and 20 per cent are high
(>57 kg/ha) in available phosphorus.
 About 11 per cent of the soils are low (337 kg/ha) in available potassium.
 About 20 per cent of the soils are low in available sulphur, 48 per cent are medium
(10-20 ppm) and 6 per cent are high (>20 ppm) in available sulphur.
 Available boron is low (1.0 kg/ha).
 Available iron is sufficient (>4.5 ppm) in 70 per cent area and deficient (
