PHOSPHATE ROCK products are an excellent natural source of phosphorus, calcium and many essential trace elements. Phosphate rock has up to one fifth the neutralising power of lime. Soft Rock Phosphate can provide exceptional results and make P readily available for plants, especially if the soil is Acidic (pH 5 to 6) and low in calcium (Ca) and the soil has low levels of available P.
Phosphate Rock is a slow release organic fertiliser 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.
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.
