Soils
Forty-six soil mapping unit along with their characteristics such as depth,
texture, slope, erosion status, and drainage condition for the study area were
obtained from soil map (1:250000 scale) prepared by National Bureau of Soil
Survey and Land Use Planning, India. These spatial and non spatial data on
soils were converted into digital soil resource databases for AEZ. In general
terms, coarse loamy and skeletal soils are in side slope and top of Lesser
Himalayas and piedmont plain while fine textured soils mainly found in
alluvial plain and fluvial valleys. The soils are mostly moderately deep to deep,
however, approximately 25 % of the area having shallow soils were mainly
found in Lesser Himalayas and piedmont plain (Fig. 4).
All the land resource databases and characteristics (Fig. 1) described above
as layer or combination of layers of spatial information were integrated or
overlaid to derive different unique agro-ecological cells. These agro-ecological
cells were further aggregated to arrive at agro-ecological zones and sub zones
based on their potential to support agriculture and vegetation patterns.
