spatial variation of soil ph and soil phosphorous and their interrelationship in the plateau area of west bengal, india

The plateau of West Bengal is a part of Chhotanagpur plateau consisting of Puruliya district of West Bengal. Physiographically this region is undulating terrain composed of granite-gneiss rock. Primarily soil is lateritic in nature. Soil in this region is acidic in nature i.e. soil pH value below 7 and low available phosphorous content covering nearly 80% area. There is a close relation between acid soil and low phosphorous content. Availability of phosphorous content is decreased in both high acid and high alkaline soil. Uses of lime may be reduced the acidity of soil and increases phosphorous availability.
