Special Blends and Straights
NPK special blends are formulated to save time when multiple products are required with less commonly used ingredients. And for soil corrective treatments following cation exchange type soil analysis or just for convenience. Often three of more applications are made with straight fertilisers costing many times the small extra cost of technical blends. When sulphates are required for soil corrective treatment it is better to apply all nutrients together so that they can interact in the soil at the same time.
