agronomic effectiveness of partially acidulated asfordi phosphate rock on canola in two calcareous and non-calcareous soils
yazd asfordi phosphate rock (pr) was partially acidulated at five levels (0, 40, 60, 80, 100%) for increasing the relative agronomic effectiveness (rae) of canola (brassica napus l.), var. rgs in two calcareous and non-calcareous soils. the partially acidulated phosphate rock (papr) was compared vs. the standard fertilizer (triple superphosphate) in two levels (50 and 100 mg p/kg). this study w...
متن کاملSignaling network in sensing phosphate availability in plants.
Plants acquire phosphorus in the form of phosphate (Pi), the concentration of which is often limited for plant uptake. Plants have developed diverse responses to conserve and remobilize internal Pi and to enhance Pi acquisition to secure them against Pi deficiency. These responses are achieved by the coordination of an elaborate signaling network comprising local and systemic machineries. Recen...
متن کاملFroth flotation of phosphate rock
The development of froth flotation is traced from its earliest-known use through the discoveries leading to the present knowledge of the science. The factors influencing the flotation of non-sulfide and non-metallic minerals are discussed, and the machines used in commercial flotation operations are described. Experimental work on the flotation beneficiation of phosphate rock is presented as an...
متن کاملeffect of casein phosphopeptide-amorphous calcium phosphate and acidulated phosphate fluoride gel on erosive enamel wear
background: some studies have shown that casein phosphopeptide-amorphous calcium phosphate (cpp-acp) and acidulated phosphate fluoride (apf) gel can protect teeth against erosion. the aim of this study was to assess whether cpp-acp and fluoride could reduce enamel wear rates under erosive conditions simulating abrasion and acidic diet regimen. materials and methods: enamel specimens consisted o...
متن کاملCALCIUM PHOSPHATE CEMENT: STUDY OF (BETA-TRICALCIUM PHOSPHATE, DICALCIUM PHOSPHATE AND CALCIUM CARBONATE SYSTEM
Calcium phosphate cements (CPCs), using B-tricalcium phosphate (ß-TCP, Ca3 (P04)2), dicalcium phosphate (DCP, CaHP04), calcium carbonate (Ca CO3), and hydroxylapatite (HAp, Ca10(P04)6(OH)2) as powder cement and disodium hydrogen phosphate (Na2HP04) solution as liquid component were prepared. After mixing the powder and liquid constituents, injectable and self-setting calcium phosphate cements (...
