Abstract

The use of rock phosphate (RP) is a strategy to complement phosphorus fertilization; however, these sources do not have the P readily available to plants. Recent studies have shown that the solubility is a property inherently associated to the particle size, which can significantly increase the solubility with a suitable reduction of particle until nanometric size. Therefore, the properties of nanoparticles suggest potential application to increase the solubility of RP. However, the agglomeration trend is a difficulty presented in the nanoparticles use. The elemental sulfur (S0) is a potential matrix to disperse the phosphate nanoparticles, that could be obtain by extrusion at low temperatures. Besides the dispersion effect to solubilize the acid generated from the S0 oxidation to sulfate (SO42-), it may contribute to the phosphate nanoparticles solubilization. The inoculation of oxidize elemental sulfur fungi, such as Aspergillus niger, can control and potentiate the S0oxidation in different soils. Therefore, our central objective is to develop a new fertilizer, based on the natural phosphate nanoparticles dispersion in an elemental sulfur matrix in different proportions, and inoculated with A. niger to control the oxidation of S0. Other objectives are to assess its solubility, the P and S interactions with the soil and the nutrients recovery by plants. The preparation of the new fertilizer is extrusion process based from RP crushed fractions to nanometer ranges dispersed in the S0 matrix by this method. After the evaluation of the ability of the fungus A. niger to oxidize S0, routes will be developed to facilitate the fungal spores inoculation during the nanocomposites synthesis. The nanocomposites characterization will be conduct and the P and S release will be evaluate, associate to the speciation of these nutrients in soil and its availability to plants.
