Studies on Physical, Chemical and Amorphous Constituents of Associated Red and Black Soils: A Case Study in Hatti Schist Belt of North Karnataka.

ABSTRACT

Associated red and black soils of the transect from Hira region of Hatti schist belt were studied for their properties. Soils were moderately deep to deep, reddish brown (5YR 3/4) to dark black (10YR3/2), clay in texture. The pH ranged from 7.56 to 7.7, EC from 0.4 to 0.44dSm-1, low to medium in organic carbon, moderate in CEC (40.1 – 54.3 c mol (p+) kg-1). Free iron oxides ranges from (0.6-3.2%), Na2CO3 extractable free silicon ranges from (0.4-3.1%) and Na2CO3 extractable free aluminium ranges from (0.2 - 2.5%).
