PHOSPHATE ROCK products are an excellent natural source of phosphorus, calcium and many essential trace elements. Phosphate rock has up to one fifth the neutralizing power of lime.
- Pacific Fertilisers Soft Rock Phosphate has the following advantages:
- The product is Pre-digested, making it more soluble than other sources such as Middle Eastern;
- Contains good P and Ca levels with the added beneficial silica and low cadmium;
- It is an Australian mined and refined product.
Pacific Fertiliser sells Rock Phosphate products that can provide exceptional results and make P readily available for plants, especially if the soil is Acidic (pH 5 to 6) with low levels of calcium (Ca) and available P.
Phosphate Rock is a slow release organic fertilizer and continuously adds P to the soil over a longer period of time. The benefits to farmers are lower costs and lower labour requirements because Phosphate Rock does not have to be applied every year. The phosphorous is not water soluble so it will not rapidly leach away, but the collodial soft rock phosphate shows good levels of citrate solubility providing good plant available nutrients.
Rock phosphate, can mineralise the soil and improve the quality of crops and soil structure. However, its principal uses are to build phosphate fertility where levels are low and/or to increase rooting activity in transplants and sprouting seeds.
