Gangetic Alluvial Zone: The alluvial soil is very deep, medium fine to medium texture, neutral to mildly alkaline in PH, calcareousness is significant in large section, base saturation moderately high, N, P status medium-to-medium low and K status is medium to high, external drainage medium to slow and internal drainage is moderate.
Vindhyan Alluvial Zone: Soil in general is deep in nature, texturally medium fine, mostly acidic in soil reaction and PH increasing with depth, external drainage medium, and internally moderate well-drained, ground water deeply placed, low in bases organic matter and phosphate (P), medium in potash (K).
Undulating Red and Laterite Zone: The region is primarily undulating with mounds and valleys and exhibiting different grades of laterisation process in soil formation.
