Soils form the second element in defining and differentiating agroecological zones as soil conditions determine important properties for plant growth, moisture supply, root aeration and nutrient supply. The third factor is land level in relation to flooding.

What is agricultural ecological zone?

An Agro-ecological Zone is a land resource mapping unit, defined in terms of climate, landform and soils, and/or land cover, and having a specific range of potentials and constraints for land use. An Agro-ecological Cell (AEC) is defined by a unique combination of landform, soil and climatic characterist.
