Data on the residual effect of rock phosphate application with FYM and EM showed significant variations on Nitrogen, Phosphorus and Potash uptake by wheat. The highest value of 125.93 kg, 8.67 kg and 17.37 kg per hectare Nitrogen (N), Phosphorus (P) and Potassium (K) uptake respectively were recorded in the plots consisted EM as compared with
effect on fruits quality. Using rock phosphate and and with the knowledge of the company producing and potassium with fertilizer on the Roselle plant produced the discovered for the ore (source Al-Ahram Mining highest growth and yield when plants were treated with Company) with the participation of …
Jun 21, 2012· Rock phosphate demand worldwide for manufacturing phosphoric acid is growing exponentially. The availability of good quality rock phosphate is limited. Till the end of last century rock phosphate quality was good and little attention was given to the effect of impurities associated with these rocks. With limited resource of good quality rock phosphate now phosphoric acid industry is …
the direct application of rock phosphate as P fertilizer. The availability of rock phosphate-P to plant largely depends on the properties of rock phosphate affecting its rate of dissolution, soil characteristics, plant species and fertilizer management practices. 3.1 Rock phosphate properties affecting its dissolution Rate of dissolution of
Rock phosphate as natural mined rock is distributed in many localities in the world and in have examined the solution of rock phosphate in soils and its subsequent effect on soil availability such as particle size of rock phosphate, soil pH and concentrations of calcium and phosphorus in soil solution (He et al., 2005).
Jan 23, 2020· Rock Phosphate’s Effect on Plants Rock dust or rock phosphate usually has a slow-releasing effect on plants. It is best applied in early spring, a little before the flowering season. You should ideally aim for 10 pounds of rock phosphate fertilizer for …
Oct 24, 2019· Long-term effects of rock phosphate on the maize rhizosphere were studied by Ubiana et al., 2017. They found that phosphate from rock phosphate may favourably alter microbial communities to improve P availability. Residual Effects on Soil P + Crop Development
ing its solubility from rock phosphate (RP) through composting, this study was planned to determine and com-pare the effect of composts prepared from different organic materials with RP on yield and P uptake of berseem and their residual effect on maize crops. 2. Materials and Methods
Field experiments were conducted to determine the effect of composts prepared from different organic materials with rock phosphate (RP) on yield and P uptake of berseem and their residual effect on maize crop (cv. Azam) during 2011-2012. Composts prepared from RP fed farm yard manure (FYM), simple FYM, organic waste and city garbage were applied at the rate based on their P concentrations.

Apr 30, 2019· The product transported away from the surface of the rock phosphate particles and recognized the positive effect of organic matter on rock phosphate dissolution. 1.2.8. Influence of plant species on rock phosphate dissolution. Ability of plants to extract P from rock phosphates was recognized by Merril, quoted in Flach et al. . Plants affect
an observable effect on number of leaves plan-1. Our results are in accordance with  who studied the effect of bio-fertilizers on the growth and yield of green gram (Vigna radiata). Our results are according to  who reported that the effect of seed inoculation with Rhizobium and phosphate solubilizing bacteria.
Rock phosphate is the raw material used to manufacture most commercial phosphate fertilizers on the market. In the past, ground rock phosphate itself has been used as a source of P for acid soils. However, very little rock phosphate is currently used in agriculture due to low availability of P in this native material, high transportation costs
Rock phosphate is the source of chemical phosphorus fertilizers but its solubility is very low and one of the solutions for increasing its efficiency is application of phosphate solubilizing microorganisms. A greenhouse experiment was performed with Bacillus subtilis and Pseudomonas putida, five levels of rock phosphate …
