| Abstract | In this work, we detd. the mol. and morphol. structures of complex granulated org. and organo-mineral fertilizers (OGFs and OMFs) obtained from poultry manure and mineral additives, such as diammonium phosphate (DAP) and potassium chloride (KCl). XRD data indicated complex compns. of the mineral additives DAP and KCl, while OGF and OMF exhibited amorphous backgrounds with small peaks due to the common Earth crust minerals (Si, Mg, Zn, Ca). Addn. of DAP generated several new chem. compds., while KCl did not react. Thermogravimetric anal. indirectly showed mineral-mineral interactions at high temps., as can be inferred from their 478 °C peak shift. Spatially resolved SEM-EDS anal. showed a particularly interesting colocalization of potassium, sulfur, and phosphorus within the OMF, suggesting a reactive salt interaction between DAP and minerals inherently present in OGF. FTIR anal., on the other hand, did not show significant involvement of org. moieties with the interactions of mineral additives, suggesting org. compds. act mostly as inert support for DAP and KCl. Collectively, these data suggest a complex nature of the OGF and OMF at the mol. and cryst. levels, which improves our understanding of these complex systems with direct relevance to sustainable nutrient management.
