Importance of soil organic carbon (SOC) in maintaining soil productivity and natural ecosystem has been a major concern throughout the globe. SOC in the humid tropical climate becomes more important in view of undulating hilly terrain in the north eastern region of India. The major concern in such landscape is soil erosion and the necessary conservation practices. In the present study, we discuss the technique of pedometric mapping to link SOC and soil loss.
Innovative methods are increasingly important to utilize existing soil information and in this context spatial soil information systems play an important role. Soil is an important component of land use planning as it acts both as a source and sink of energy for many functions of the land. In general, all living and non-living things on earth get their energy for functioning from the soil in the form of nutrients, water and air.
