Six representative soil profiles were collected from different landform units of ER
upland to assess land productivity index based on parametric approach. Soils,
developed on different physiographic units viz., hill, pediments, valley, very
gently sloping, nearly level plains were studied for their characterization,
classification and potentiality evaluation. Morphologically soils showed considerable
color variations with dominant hue of 10YR. The sand, silt and clay content in
soils of ER upland ranged from 8.10 to 53.87%, 28.73 to 45.67% and 16.07 to
49.75%, respectively. The Bulk density showed increasing trend with the depth
–3 and varied from 1.43 to 1.68 Mg M . Soils on valley and plains were well
developed as compared to those on hill and pediments. The soils are classified as
lithic Ustorthents (P and P ), Typic Haplustepts (P , P and P ) and Typic 1 2 3 4 5
Haplusterts (P ). The productivity of hill and pediments soils was extremely 6
poor for crop (1.57%), pasture (5.89%) and tree (0.12%). Agriculture
productivity of valley, pediments and plains (P -29.43%, P -31.07%, P -27.62% 3 4 5
and P -31.07%) was assessed as average. With adoption of improved package 6
of practices like moisture conservation, addition of organic manures etc., the
productivity class of these soils can be upgraded to good (from 50.40 to 53.87%).
The potentiality of ER upland soils for crop, pasture and commercial crops
production can be improved as indicated by coefficient of improvement (varied
from 0.93 to 5.23%). The soils on Sawantgarh series (P ) and Raitoda series (P ) had 4 6
the highest potentiality for crop and pasture production.
