What is the difference between agro climatic and agro-ecological zones?
An “Agro-climatic zone” is a land unit in terms of major climates, suitable for a certain range of crops and cultivars. An agro-ecological zone is the land unit carved out of agro-climatic zone superimposed on landform which acts as modifier to climate and length of growing period.
