Blaukorn® N-Max 24-5-5 is a high-quality fertiliser which can be used on grassland, grazing paddocks, pastures, and hay fields. Blaukorn N-Max is low in potassium and phosphorus so is ideal for use on soils with a good supply of this nutrients whilst still providing the growing grass plant with the nitrogen it requires. Two sources of nitrogen are used in the fertiliser to ensure even nutrient release over a 4-6 week period.

Each granule of Blaukorn N-Max fertiliser contains the three major nutrients, nitrogen, phosphorus, and potassium which support strong, healthy leaf and root growth and improve stress resilience. Magnesium and Sulphur are also included in the formulation to assist with photosynthesis and effective use of nitrogen.
