2.1. Phosphate Rocks and Additives Two high-reactivity sources of RP (Bayovar from Peru and BG4 from Morocco) and one low-reactivity source (Araxá from Brazil) were used as raw material for the production of partially acidulated phosphate fertilizers. Their chemical parameters and composition and total P2O5, 2% citric
That was a $64 billion ($64B) global industry in 2014. The U.S. organic market alone is a $25–30B industry that is growing at 9% a year. Organic farmers must use natural fertilizer, and the rock from our Bayovar 12 phosphate project in Peru is one of the best natural rocks in the world.
The report further highlights the work of a Peruvian visiting scientist who studied Bayovar phosphate rock, a potential indigenous fertilizer for Peru's agriculture. The scientist evaluated the agronomic effectiveness of the rock on different crops and soil types, presenting promising results and suggesting further field testing.

However, bacterial strains promoting rock phosphate solubilization increases P use efficiency and can be applied to BBFs. Methods An in vitro assay was conducted to investigate the solubilization ...
3) Bayovar Rock Phosphate Specification . An independent research trial over a 5-year period has shown that using high reactive rock phosphate fertilizer such as Bayovar Rock Phosphate can improve oil palm yield …
slowly than soluble phosphate fertilizers, where practically all water-extractable P is released in the first 24 h, and the dissolution rates vary among the types of phosphates used for biomass enrichment (Lustosa Filho et al. 2017). Thus, biochar enrichment with reactive rock phosphate, such as Bayóvar rock phosphate, is an option to produce BBF,
The largest phosphate deposits in the world are found in ancient sedimentary basins. The phosphates discovered on the Bayovar 12 property occur within the "Diana Formation"; a sequence of rocks composed of diatomites and sandstone. Diatomite is a type of sedimentary rock composed of fossilized, single celled algae known as diatoms.
Phosphate-solubilizing bacteria (PSB) exhibited a high efficiency to improve plant growth and nutrition in the presence of Bayovar rock phosphate when sand-vermiculive was used as a culture medium. Treatments with dual inoculum (PSB plus mycorrhiza) significantly (P≤0.05) increased alfalfa growth.
The project is capable of producing 3.9Mtpa of phosphate concentrate with a minimum grade of 29% of phosphorus pentoxide, which is mostly used in fertilisers. …
The Bayovar–Sechura phosphate rock usually named Sechura phosphate rock SPR is able to dissolve at least 30% of the total phosphate concentration with 2% citric acid, therefore, it is included in the Reactive …

High reactive rock phosphate (BG4, from Gantour phosphate mine, Morocco) and triple superphosphate (TSP) from Morocco were used as positive controls. ... Effect of phosphate-solubilizing bacteria and vesicular-arbuscular mycorrhizal fungi on the utilization of Bayovar rock phosphate by alfalfa plants using a sand-vermiculite …
The project is capable of producing 3.9Mtpa of phosphate concentrate with a minimum grade of 29% of phosphorus pentoxide, which is mostly used in fertilisers. Vale has invested $556m in the project. The mine is being operated by Vale's subsidiary Miski Mayo. See more
Rock Phosphate (RP) is any naturally occurring geological material that contains one or more phosphate minerals suitable for commercial use. There is a major RP deposit in Eppawala, Sri Lanka and ...

Focus Ventures Ltd. is pleased to provide an update on recent progress from the Bayovar 12 phosphate project in northern Peru, including preliminary results of bench scale metallurgical testwork.
The Bayovar rock will be used in Mosaic's global phosphate operations. Total consideration to be paid by Mosaic to Vale for its stake in the joint venture will be $385 million .
The experiment was established in August 2013 with two phosphate sources (TSP (triple superphosphate) and RP (Bayovar rock phosphate)) and three application methods: as broadcast, at planting furrow and combining half broadcast/half plant furrow, all at the rate of 180 kg ha −1 soluble P 2 O 5 being applied at crop …
FOSPAC is a subsidiary company of Pacasmayo dedicated to explorations and the production of rock phosphate in Bayovar, Piura Province, Peru. MC and Zuari have established a joint venture based in Singapore, MCA Phosphates Pte Ltd. (MCA), for MCA to acquire a 30% stake in FOSPAC. This will enable MC to hold 21% stake in FOSPAC …
Phosphate rock production at Bayovar and deliveries to Mosaic are expected to begin in the second half of calendar 2010. "This transaction advances our strategic objective to secure additional phosphate rock outside of North America," said Jim Prokopanko, Mosaic's President and Chief Executive Officer
The rock phosphate, being an insoluble phosphate, induces a higher secretion of phosphatases, for example, which facilitates the release of phosphorus to the plant promoting growth 55. The ...
Abstract. Purpose: The co-pyrolysis of biomass and soluble phosphates generates biochar-based phosphate fertilizers (BBF), which may enhance phosphorus (P) input in soil and …
The concentration of S was between 0.1 g kg −1 (wood sawdust biochar pyrolyzed at 350 °C) and 16.8 g kg −1 (coffee husk biochar enriched with Bayovar rock phosphate and MgO). Finally, for biochars prepared from swine manure, poultry litter, and sewage sludge, concentrations of Na were below the detection limits.
Phosphate chemical fertilizers are extensively used to improve agricultural productivity. However, the production of these fertilizers is expensive and can cause environmental damage. Alternatively, microbial solubilization of rock phosphate (RP) is a potential strategy for obtaining biofertilizers.This paper proposes the use of a novel …
The co-pyrolysis of biomass and soluble phosphates generates biochar-based phosphate fertilizers (BBF), which may enhance phosphorus (P) input in soil and P uptake by plants. Conversely, pyrolysis of biomass impregnated with rock phosphate results in low P solubility and may not supplement plant requirement in short term. …

Soluble phosphates are the most common sources currently used in crop production in tropical soils; however, they present low efficiency and are more expensive than natural rock phosphates. The objective was to develop new phosphate fertilizers with slow solubility through the partial acidification of rock phosphates (RPs), incorporating …
T13 = ARP (Araxá rock phosphate); T14 = BRP (Bayovar rock phosphate); T15 = MRP (Morocco rock phosphate); T16 = TSP (triple supe rphosphate); T17 = control. P ILC = pillared clay;
The phosphate sources were Simple Superphosphate (SS, 18% of P 2 O 5), Catalão rock phosphate (CA, 2.93% of P 2 O 5) and Bayovar rock phosphate (BA, 14% of P 2 O 5).
