GAIA GREEN® ORGANICS Rock Phosphate is a naturally occurring mineral, which has been ground to a fine powder. Plants with high cation exchange root systems (legumes and grains) are found to be effective in obtaining phosphorous from soil and rock phosphate. This product can be very effective when used in conjunction with cover cropping.
In maize, relatively higher-yield response to nano-rock phosphate was obtained as compared to micro-sized rock phosphate (Das 2011). These literatures tend to indicate …
In addition, nano-elicitors (nano-MeJ) prepared from calcium phosphate NMs functionalized with methyl jasmonate (MeJ) were used in plant defense reactions, and …
This work demonstrates the feasibility of preparing high-purity P 4 by electrolysis of dissolved phosphate in molten CaCl 2 without complex purification. The purity of the electrolyzed P 4, obtained from Ca 3 (PO 4 ) 2, was comparable to commercial 99.999 pct grade product.
This rock phosphate that has been nano-enhanced has demonstrated better . ... nanotechnology in agriculture, more research is nonetheless required. 6.5 Crop rotation and cover crops.
Beneficiation of Phosphate Rock More than 97 percent of the world's phosphate fertilizers are produced from Phosphate Rock, which might get depleted in two decades. All Phosphate Rocks, and products derived from them contain high amounts of heavy metals (e.g., Cd, Cr, Pb, Sb, V, Zn, and Cu), and radioactive elements (e.g., U, and Th) [4].
Rock Phosphate is a particular word that describes naturally occurring mineral assemblies comprising an elevated concentration of phosphate minerals (Zapata and Roy, 2004). ... Nanotechnology has led to the development of new concepts and agricultural products with immense potential to manage the aforementioned problems. ...
Rock Phosphate (RP) is theoretically the cheapest fertilizer and most abundant, but its direct application in the soils is not always agronomically effective due to its low phosphorus (P) availability. An environmentally friendly and economically alternative to traditional processing of these deposits is the use of Phosphate Solubilising Microorganisms (PSM). …
While TEM appears the crystals size of converted rock phosphate was found in nano size (19.7 -39.1 nm). Moreover Sterio microscopy illustrated that, after calcination and zeolitization …

Both nano-rock phosphate types were amended at 1140 P kg ha −1 to meet the recommended dose rate for P. Treatment pots were arranged in a completely randomized …
Rock phosphate (RP) is an important natural material traditionally used for the production of phosphorus (P) fertilizers. Compared with chemical treatment, microbial solubilization of RP is an alternative environmentally mild approach. An overview of biotechnological techniques, mainly based on solubilization processes involving agro-industrial …
Phosphate Rock (uncalcined) Description. An ore where phosphorus and oxygen are chemically united. Its colour depends on where the source of this cargo comes from - can be from tan to dark grey. Dry and dusty. Moisture : 0-2%. Also depending on where the cargo comes from, it may have flow characteristics but not liable to shift once settled.
Eppawala rock phosphate (ERP). Apatite occurs as massive, discontinuous bodies in a Precambrian, high-grade metamorphic terrain. When these apatite-bearing carbonate rocks are weathered they form economically important phosphate deposits. The naturally occurring Eppawala rock phosphate contains 28% to 42% phosphorus as P 2 O 5 (Pitawala …
Despite the fact that nanotechnology gives rock phosphate a relatively smooth shape with a higher aspect ratio and greater specific surface area, the presence of microscopic holes in nano rock phosphate may accelerate P release due to higher nutrient dissolution when water enters these holes.
Present investigation aimed to convert rock phosphate ore into nano zeolite using calcination (from 200 to 700°C) for 48 hrs. and zeolitization (replacement by a zeolite mineral) processes in order to boost rock phosphate ore efficiency …
The first factor is the type of fertilizer, consisting of nano guano, nano phosphate rock, and SP-36. The second factor is the dose of P 2 O 5 with four treatment levels, namely 0 kg.ha -1, 50 kg.ha -1, 100 kg.ha -1, and 150 kg.ha -1 . The results showed that nano phosphate rock was the most effective fertilizer for maize in Inceptisol.

Nanotechnology, the science as well as the art of manipulating matter at atomic or nanoscale (1 nm = 10–9 m) is cutting edge technology in agricultural sciences.
Also considering that inorganic P mined as phosphate rock is a nonrenewable resource, these issues have prompted an interest in nano-enabled P delivery strategies. We synthesized biodegradable polymer composites (PCs) containing polyhydroxyalkanoate (PHA) and a variety of calcium phosphate-based P sources, including nano-scale calcium ...

ABSTRACT. To examine the effect of nanoparticulate phosphate rock (NPR) as both a agent and phosphorus source in a tropical acid soil. The study examined five rates of NPR (0, 250, 500, 1000, or 2000 kg ha −1), which supplies 30, 60, 120 or 240 kg P ha −1, in a randomized complete pot experiment design with 3 replications.The pots of soil were …
In parallel, we investigate citrate-stabilized nano-rock phosphate (nRP), and demonstrate that it possesses equivalent plant bioavailability as synthetic nHAP. Since nRP was prepared …
A disturbing fact is that the fertilizer use efficiency is 20-50 percent for nitrogen, and 10-25 percent for phosphorus (<1% for rock phosphate in alkaline calcareous soils).
The resultant regenerant solution is a nearly saturated solution of reactive, bioavailable phosphate fertilizer. The advent of nanotechnology allows for tremendous increases in metal oxide surface area compared to the macro counterpart. This in turn provides the favorable kinetics needed for making phosphate adsorption cost-effective.
