The land resource inventory of Hongahalli-2 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 644 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 64 per cent is covered by soils, 25
per cent by forest and 10 per cent by others. The salient findings from the land resource
inventory are summarized briefly below.
 The soils belong to 10 soil series and 20 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 64 per cent area is suitable for agriculture.
 About 17 per cent of soils are shallow (25-50 cm), 16 per cent are moderately shallow
(50-75 cm), 12 per cent of the soils are moderately deep (75-100 cm), 9 per cent of the
soils are deep (100-150 cm) and 10 per cent are very deep (>150 cm).
 About 8 per cent of the area has clayey soils at the surface, 40 per cent area has loamy
soil and 17 per cent area sandy soils, at the surface.
 About 16 per cent of the area has non-gravelly soils and 46 per cent gravelly soils (15-
35 % gravel) and about 2% very gravelly (35-60%) soils.
 About 33 per cent has soils that are very low (200
mm/m) available water capacity.
 Entire area of about 53 per cent has very gently sloping (1-3% slope) and 11 per cent
soils are gently sloping (3-5%) lands.
 An area of about 31 per cent has soils that are slightly eroded (e1) and 33 per cent
soils are moderately eroded (e2).
 An area of about 16 per cent has soils that are neutral (pH 6.5-7.3), an area of about
34 per cent has soils that are slightly acid (pH 6.0 to 6.5) and 13 per cent has soils that
are moderately acid (pH 5.5 to 6.0).
 The Electrical Conductivity (EC) of the soils are 0.5%) and 6 per cent of the soils are medium
(0.5-0.75%) in organic carbon.
 About 41 per cent of the soils are medium (23-57 kg/ha) and 23 per cent are high
(>57 kg/ha) in available phosphorus.
 About 1 per cent of the soils are low (
