How are land capability classes determined?
Land capability classification (LCC) may be defined as a system of grouping land in to various classes based on inherent limitations imposed on sustained use by soil attributes, topography, drainage and climate. The guiding principle underlying LCC is “use land according to its capability and treat it as per its need”.
