Abstract
The Present work aimes, Identify and quantify spatial variability within fields using GIS. Delineation and analysis of soil fertility management zones based on GIS. Identification of wheat yield-limiting nutrients.
objective of the study is to optimize the use of fertilizers especially nitrogen, phosphorus, and potassium fertilizers based on local specific conditions of the soil. Specifically:
• Identify and quantify spatial variability within fields using GIS.
• Delineation and analysis of soil fertility management zones based on GIS.
• Identification of wheat yield-limiting nutrients.
Inventory the nutrient balance using compositional nutrient diagnosis model (CND).
