On the other hand, rock phosphate (RP) constitutes a rich-in-phosphate rock, which can serve as a natural plant fertilizer. Nevertheless, the solubility of RP remains partial. Furthermore, aspects like pH, calcium ion (Ca 2+ ), and dihydrogen phosphate ion (H 2 PO 4 − ) absorption capacity can interfere with RP solubility (Nahas 1996 ).

The objective was to develop new phosphate fertilizers with slow solubility through the partial acidification of rock phosphates (RPs), incorporating materials with …

The solubilization of rock phosphate (RP) by four yeast strains, Rhodotorula sp., Candida rugosa, Saccharomyces cerevisiae and Saccharomyces rouxii, which were isolated from wheat rhizospheric soils, was investigated in this study. The yeast isolates demonstrated diverse levels of soluble phosphate releasing abilities in modified …

In the first experiment, PSBs were isolated from the rhizoplane of native plant species grown in a rock-phosphate (RP) mining area. A subset of 24 bacterial isolates from 210 rhizoplane morphotypes was selected for the inorganic phosphate solubilizing activities using tricalcium phosphate (TCP) as the sole P source.

Rock phosphate (RP) addition in cow-dung waste-paper mixtures at rates above 2% P has been reported to increase the rate of bio-transformation and humification of organic waste mixtures during vermicomposting to produce organic fertilizer for organic farming. However, the optimization of RP for vermicomposting was not established. The …

1.. IntroductionThe aluminosilicate minerals known as zeolites, when saturated with mono-valent nutrient cations, such as NH 4 + and K +, have been reported to increase the solubility of rock phosphate (RP) (Allen et al., 1993).The mechanism proposed to account for the solubilisation of RP is exchange-induced dissolution.
