Elements Of

The essential elements of the core applications of AEZ include :

□ Land resource inventory, comprising

• Analysis of length of growing period or moisture availability index

• Defining thermal zones

• Compilation of climatic resource inventory

• Compilation of soil and landform resource inventory

• Compilation of present land use inventory

• Combination of above to make land resource inventory based on agro-ecological zones or agro-ecological cells.

□ Inventory of land utilization types and crop requirements

□ Land suitability evaluation, including

• Potential productivity computations

• Matching of constraints and requirements

Data base for definition of Agro-Ecological Zoning

Data base for definition of Agro-Ecological Zoning

Information in computerised GIS form for each cell. Thermal regimes (3 zones) soil moisture (8zones) Rainfall (5 zones) Soil Texture (3 classess) Slope (4 classes) Physiography (3 types) Elevation (5 zones) Soil unit (47 types) Landuse (10 classes)
