Phosphate Rock
Rock Phosphate is a vital agricultural mineral widely used as a natural source of phosphorus (P₂O₅) for crop production. It is derived from phosphate-rich sedimentary rocks and serves as a key raw material in the production of phosphate fertilizers.
This product is particularly effective in acidic soils, where it gradually releases phosphorus, ensuring long-term nutrient availability for plants. Phosphorus plays a critical role in root formation, flowering, seed development, and overall plant vigor.
Rock Phosphate is suitable for a wide range of crops including cereals, legumes, vegetables, and plantation crops. It is also highly recommended for organic farming systems due to its natural composition and environmentally friendly properties.
Dolophos Phosphorus Fertiliser
This is a granular mineral based product that provides slow release Phosphate throughout the growing season for use in Horticulture, Tillage and Grassland. It also contains important secondary nutrients including 30% Calcium, 2% Magnesium (MgCO3) as well as Manganese, Zinc, Copper and Molybdenum. Phosphate is vital for root growth and plant establishment. Due to its gradual release, Dolophos matches crop uptake. Approved for use on organic holdings subject to approval from your certification body.

- Leaves that turn blue/green and become stiff
- Fruits small and acidic tasting
- Poor yield of fruit
- Phosphorus deficiency may be confused with nitrogen deficiency
