ABSTRACT Demand for phosphate fertilizers in Brazil, combined with its reliance on external sources, highlights the need to explore alternative phosphorous (P) sources for limed cultivated soils. This study aimed to characterize and evaluate the agronomic performance of phosphates from various sources, including national sedimentary (Arraias, Bonito, and Pratápolis) and igneous deposits (Catalão and Registro) imported sedimentary sources (Algeria, Bayovar, and Morocco), and residue-recovered sources (Bonechar and effluent recovered phosphate – ERCP). Phosphates underwent mineralogical and chemical characterization, including P […]

ABSTRACT: The use of mineral phosphate fertilizers associated with organic residues can improve fertilizer use efficiency and consequently decrease their usage costs. Soil application of filter cake (FC) can provide nutrients and enhance physical quality. This study aimed to evaluate the effects of different phosphate fertilizers [rock phosphate (RP) and triple superphosphate (TSP)] applied at different rates (90 and 180 kg ha-1 P2O5) associated with filter cake (10 Mg ha-1 dry matter) on the soil phosphorus (P) fractions after two […]
