Phosphate rock from CROPS' Bayovar12 project in the Sechura region of northern Peru is naturally occuring, free-digging, highly reactive phosphate rock
(RPR), effective as a slow-release source of P in acid to mildly acid soils, adding P to the soil over a longer period of time than some manufactured fertiliZers. It is one of the most reactive, naturally occuring soluble, rock phosphates in the world. It can also be upgraded to a concentrate by washing and flotation for use in the manufacturing of phosphoric acid.
Visually resembling beach sand when dry, Bayovar RPR is made up of fine, brownish particles of natural phosphorus minerals - mainly the calcium phosphate mineral Apatite - that can be applied directly to pasture or crops. The RPR also contains Gypsum - natural calcium sulphate - and reacts well with natural acids in the soil slowly releasing phosphorus.
The 12,500-hectare property hosts 13 stacked horizontal beds of free-digging phosphate rock containing phosphorus pentoxide (P2
). With only one third of the property examined by exploration drilling, the Bayovar 12 project already has a large, world class NI 43-101 mineral resource from which the Company is proposing to produce 1-million metric tonnes of rock concentrate per year. The results of an independent updated pre-feasibility study were published in May 2016.
If you'd like to read more about the effectiveness of RPR as a fertilizer, we've collected dozens of references from agronomy journals and general science publications that cover pretty much every aspect of the science of reactive phopshate rock. The references are linked here
