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%).
