The unit provides the informations required by the Agriculture Department, Irrigation Department, Research Institutions, Corporations, Municipalities and Panchayaths. It collects detailed informations about the various characteristics of soil besides exploring the reasons for the loss of soil quality. Crops suited for different localities can be selected based on the statistics of the unit. The reports of the unit are also useful for conserving the fertility status of the soils, in deciding the agricultural practices and irrigation schemes suitable to different watershed regions and in the shaping of location specific research programmes.
