Sep 06, 2019· But rock phosphate is a finite resource and the biggest supplies are mined in politically unstable places, posing risks to the many countries that have little or no reserves.
The global resources of rock phosphate are of the order of 163,000 million tonnes. Africa contains about 41%, USA has 21%, USSR 13%, the Middle East 10%, Asia 8%, South America 3%, NewZealand and ...
Mussoorie rock phosphate contains a high level of iron. Therefore it is not considered suitable for commercial processing. The present work was undertaken to make a comparative study on the efficiency of Mussoorie and imported rock phosphate for manuring of rubber plants by conducting laboratory as well as greenhouse studies. It was found that between the two rock phosphates tried, no ...

Comparative Solubility Study of Four Phosphatic . %P)) and Mussoorie rock phosphate (MRP %P) whose solubility were tested in s ix different extractants namely 2% Citric acid, Hydrochloric acid, NAmmonium citrate, Bray2P extractant, Olsens''s extractant and Morgan''s reagent under seven periods of incubation (1, 2, 3, 7, 10, 15 and 30days), with and without soil.
In two field experiments, Mussoorie rock phosphate with or without pyrite, farmyard manure or straw was compared with concentrated superphosphate when applied to guar and groundnut. The treatments included rates of 10, 20 and 30 kg P/ha and were located on a soil low in available phosphorus.
The agronomic effectiveness of a partially acidulated phosphate rock (PAPR) was measured in a field experiment with sorghum (Sorghum bicolor cv. CSH6) in a shallow Alfisol at the ICRISAT farm, Patancheru (Hyderabad), India. The experiment compared PAPR with single superphosphate. The PAPR was made by acidulating an indigenous Indian phosphate rock (Mussoorie) with H2SO4 at 50% .

ROCK PHOSPHATE: ITS AVAILABILITY AND SOLUBILIZATION . ROCK PHOSPHATE: ITS AVAILABILITY AND SOLUBILIZATION IN THE SOIL – A REVIEW Kiran Kumari and V. K. Phogat Department of Soil Science, CCS HAU, Hisar, Haryana, 125001, India ABSTRACT A high grade quality rock phosphate is an essential requirement for manufacturing of phosphatic fertilizers.
Partial acidulation of phosphate rock. Partially acidulated phosphate rocks (PAPRs) are prepared by reacting PRs, usually with H 2 SO 4 or H 3 PO 4, in amounts less than that needed to make SSP or triple supersphosphate (TSP), respectively. The use of PAPRs has been widespread in Europe and South America since Nordengren (1957) first reported ...

mussoorie rock phosphate at varying rate of application on growth, yield and economics of potato. The field experiments were conducted during 2001–04 at
The field experiments conducted during 200104 at New Delhi to study the effect of crop residue incorporation on the relative efficiency of diammonium phosphate and mussoorie rock phosphate at varying rate of application on growth, yield and economics of potato (Solanum tuberosum L.). Results showed phosphorus application significantly increased growth and yield parameters, yield (mean tuber...
Mussoorie rock phosphate was the least effective source of fertilizer phosphorus, although its efficiency is considerably higher for the legume clusterbean and for groundnut than for the cereal wheat. The efficiency of Mussoorie rock phosphate increased when it was mixed with the soil together with Amjhore pyrites, farmyard manure and straw ...

Treatments consisted of four levels of phosphate (40,80, 120 and 160 kg P 20S ha1 as Mussoorie rock phosphate (MRP) with and without inoculation of Aspergillus nigerVan Tiegh.(phosphate dissolving fungus). A treatment with 40 kg P Ps ha1 as single superphosphate (SSP), was also included in the study as a standard. Treatments were randomised
These isolates also showed relatively high solubilization of North Carolina rock phosphate (NCRP) in comparison to the solubilization of Mussoorie rock phosphate (MRP) and Udaipur rock phosphate (URP). The solubilization of phosphate substrates by P. trivialis and P. poae is reported for the first time. PMID: [PubMed indexed for MEDLINE]
