Agro-climatic Zones

The agro-climatic classification is nothing but an extension of the climate classification keeping in view the suitability to agriculture. Earlier many methods have been devised for climatic classification and the most widely used classifications being Koeppen’s and Thronghwaite’s. Generally, the climate types may be distinguished on the rainfall, temperature and as these two characteristics are influenced by altitude, the climate can also be classified on the basis of above three parameters. National commission on agriculture (1971) classified the country into 127 agro-climatic zones. The planning commission has adopted agricultural Zones on the various parameters for agricultural planning. The soil climatic zones can be classified on the basis of rainfall, temperature and prevalent soil types in the region.
