Medium Black Soils of Karnataka

1. These soils usually occur in the Deccan trap, schist, lime stone and shale region of the state, occupying areas in parts of Bidar, Gulbarga, Bijapur and Belgaum districts and to some extent on peninsular gneiss area in Raichur, Chitradurga and Dharwad districts.

2. These soils are moderately deep to very deep (23-90 cm), dark to very dark in greyish brown, dark reddish brown or black in colour, usually calcareous, cracking, clayey soils.

3. These are highly moisture retentive,


Shallow Black Soils of Karnataka

1. These shallow soils are usually encountered on undulating ridges in the Deccan trap region and to some extent on schist and lime stone upland region of Karnataka, occupying areas in north and north-west parts of the districts of Belgaum, Bijapur, Gulbarga and Bidar.

2. These are shallow (less than 23 cm), dark greyish brown, dark brown to dark reddish browm, usually calcareous, with gravelly clay loam to clay in texture.

3. They are neutral to weakly alkaline and have moderate


Types of Soils present in Karnataka

1. A scientific knowledge of soils is a pre-requisite to understand the local ecology and useful in planning for agricultural development.

2. As per the updated soil survey data, the soils of Karnataka have been broadly classified under nine groups.

The characteristics and distribution of these nine soil groups in different parts of Karnataka are as follows:

Seasons of karnataka

Major Rice growing seasons of Karnataka can be broadly classified into three seasons, viz., kharif, Hingaaru, Besige. 1. kharif (Mungaaru in Kannada) (June-July) : In all the rice growing ecosystems of Karnataka Kharif sowing is common. while during Summer season the crop is cultivated mainly in the irrigated maidan areas of north and south. 2. Hingaaru (Rabi) season: In tank-fed areas, the crop is taken up late in the season (August-September) (called Hingaaru in Kannada) dependi

Soil reclamation in Karnataka

1. The effect of FYM application was found to be comparable or even superior to lime amendment on the acidic soils which seemed mainly due to the formation of A1-organo-chellates, resulting in the reduction of A1 concentration in soil solution to levels beneficial to plant growth. 2. Similarly, in the red soils of Hyderabad, the average increase in rice yield due to NPK+FYM was 17-21 percent in both Kharif and Rabi seasons. 3. These and other results suggest that substitution of 25-50 per
