Description A study was undertaken to characterize, classify and map the soil resources of a
village derived from chlorite schist in northern transitional zone (zone-8) of Karnataka in
order to assess their land capability, irrigability and suitability for crops and also to assess soil
fertility constraints.
Mantagani village in zone-8 of Karnataka was selected as the study area. Soil survey
was carried out to know the type and extent to soils prevailing in the area and to map the
soils. Fourteen profiles were studied for the morphological, physical and chemical properties
and classified up to family level and identified 7 series. The identified series are mapped into
16 mapping units. Land capability classification was carried out for the study area. The land
capability classes namely IIIsf, IIItsf, IIIwsf, and IVt have been differentiated and mapped.
Soil suitability evaluation for irrigation showed that soils were moderately suitable (S2) and
marginally suitable (S3) for surface irrigation. The mapped soils from the study area were
assessed for the suitability of crops like cotton, wheat, maize, chilli, jowar, sunflower, pearl
millet, groundnut and pigeonpea. Mantagani soil series were moderately (S2) and marginally
suitable (S3) for crops like cotton, wheat, maize, chilli, jowar, sunflower, groundnut and pearl
millet. Soils are currently not suitable for pigeonpea (N1) with limitations of pH and ESP.
One hundred fifteen samples (0-30 cm) drawn from the farmers? fields were analysed
for their fertility status and mapped by GIS technique. The pH of soil samples was slightly
acidic to alkaline. Soil organic matter content was low. Available nitrogen, phosphorus was
generally low to medium and available potassium and sulphur were low to high. Regarding
available micronutrients, zinc and iron were deficient where as, copper and manganese were
deficient to sufficient in these soils.
