Based on the three years work on soil survey, soil suitability and crop planning using Remote Sensing and GIS, soil resource based crop planning and soil management techniques were developed for sustain the crop production. It provides the state of the art literature review, including on methodologies of the land evaluation and standard methods of soil survey and quality assessment.
