The main focus in this discipline is on the design of well-balanced fertiliser programs based on all the contributing variables and exploitation of new technology in this regard which include:

• Evaluations and recommendations on the suitability of soils for specific crop types and recommendations on physical and chemical improvements to soils.
• Development and compiling of fertiliser programmes based on soil and leaf analyses together with production and growth history of an orchard, vineyard or field.
• Compiling of foliar fertiliser spray programmes based on leaf nutrient analyses.
• Compiling of three year lime maintenance programmes of soils.
• Implementation, modification and guidance of nutritional programmes throughout the season in orchards and vineyards to ensure a good balance between growth and fruit baring.
