Superphosphate and Rock Phosphates as Phosphorus
The objective of this research was to evaluate sources of phosphorus (P) and lime rates surface applied on natural pasture for exotic cold season foragesthe principal conclusions to be drawn from this series of trials are that: (a) reactive phosphate rock (rpr) is relatively ineffective as a fertiliser compared with superphosphate in the first year following application on a wide range of developed pastures; (b) after several years of regular use rpr can become as effective as superphosphate inThe longterm effectiveness of reactive phosphate rock

The Project Overview — Chatham Rock Phosphate
Rock phosphate is an essential ingredient of manufactured fertiliser and can (if of the appropriate chemical composition) be applied directly to pasture with less environmental damage from runoff than manufactured superphosphate Extensive exploration in the 1960s, 70s and 80s identified the potential for a 100year supply for the New ZealandRock phosphate from Duchess, northeastern Australia, and superphosphate were compared as phosphorus (P) sources for pasture in glasshouse and field experiments in northern Queensland Duchess rock(PDF) Low Effectiveness of Duchess Rock Phosphate on
Use of phosphate rocks for sustainable agriculture
The principle behind the use of phosphate rock elemental sulphur assemblages (PR/S) is that the inoculated or native population of soil bacteria oxidizes S to H 2 SO 4 when the product is applied to the soil This acid in turn reacts with the PR particles that are in close proximity to S and forms monocalcium and dicalcium phosphatesOn an active pasture site, planted with Setaria sphacelata, moderate rates of urea (50 kg N ha −1 a −1), rock phosphate (10 kg P ha −1 a −1), and a combination of both were applied It was examined whether soil mineralization (gross and net N mineralization, SOC mineralization) and microbial community structure (PLFAanalysis), as wellIn an Ecuadorian pasture soil the growth of Setaria

Effectiveness of rock phosphate, coastal superphosphate
The effectiveness of ‘coastal superphosphate’ and two rock phosphate fertilizers was compared with the effectiveness of single superphosphate for pasture production on deep, humic, sandy podzols in high rainfall (> 800 mm annual average) areas of southwestern Australia The pastures were subterranean clover (Trifolium subterraneum) or mixed subterraneum cloverCalcined rock phosphate is prepared by low temperature (500°F) calcination of 'C' grade Christmas Island rock phosphate that is unsuitable for superphosphate production It was compared with superphosphate and with mixtures of superphosphate and calcined rock phosphate for pasture and cereal production at two sites in the 1218 in annual rainfall zone ofCalcined rock phosphate as fertilizer for pasture and

Phosphorus Use Efficiency in Permanent Pastures in
The phosphorus (P) availability in volcanic soils is a main limitation for permanent pasture growth Phosphorus use efficiency (PUE) must be improved to increase forage production with minimum impact on the environment The aim of the present study was to assess at field conditions the PUE, P uptake efficiency (PUPE), P utilization efficiency (PUTE), and the PThe list of acidic agents utilized to improve phosphate availability of rock phosphate can be organic and nonorganic approved, so depending on the overall objective, ie, commercial, regenerative of organic crop production, could drive the blending decision, although, many agents could be used with all three types of crop productionImproving Rock Phosphate Availability Fertoz
