Unlocking Soil Nutrition
The gap between
fertiliser prices and crop returns is increasing.
This course is designed to provide valuable information on
the ways in which soil can be managed more effectively, to
higher levels of sustainable nutrition and reduce yield-limiting
Providing opportunities to reduce input costs and improve profitability
Areas covered include:
- Understanding stages
of soil formation and resulting characteristics:
Soil components and plant relationships.
Soil water and capillarity.
Structure, texture, strata and horizons.
- The role of nitrogen
within the soil complex:
The mineralisation process explained.
The place of Humus and Organic Matter in holding and supplying
- Management of soil
explanation of pH and its significance upon nutrient supply.
Buffering capacity and the relative effectiveness of liming
Establishing the true lime requirement for different soil
- An explanation of
soil nutrient characteristics:
Measuring the nutrient holding capacity of different soils.
Understanding the soil nutrient complex.
Nutrient relationships – antagonisms and chemical lock-up
- More effective management
of soil nutrient profiles:
Removing yield-limiting factors.
Eliminating nutrient wastage and improving the bottom line.
