Available phosphorus from phosphate extracted from swine wastewater for poultry. ABSTRACT: This research evaluated phosphorus availability, from phosphate extracted from swine wastewater, in broilers. Phosphorus inorganic contaminants were determined. Afterward, an experiment was... ... Repositório: BDPA Ano de publicação: 2025
Agronomic efficiency of partially acidulated and granulated Arraias phosphate rock. Natural phosphate rocks (PR) are characterized by low phosphorus (P) solubility in water. Acidulation is the normal method to raise P solubility of these materials, however, it increases the cost and... ... Repositório: BDPA Ano de publicação: 2025
Partial acidification of Arraias rock phosphate improves P use efficiency in tropical soils. The aim of this study was to evaluate the agronomic efficiency of partially acidulated Arraias rock phosphate. The experiment was conducted in a greenhouse at the University of Rio Verde, Rio Verde, G... ... Repositório: BDPA Ano de publicação: 2019
Solubilization of phosphate rock by organic acids. Repositório: BDPA Ano de publicação: 2017
Sorghum genotypes response to inoculation with phosphate solubilizing bacteria. Sorghum bicolor adapts to phosphorus (P) deficient soils through mechanisms that contribute to its absorption and solubilization, including the association with microorganisms. The direct application... ... Repositório: BDPA Ano de publicação: 2020
Maize yield influenced by the residual effects of sedimentary phosphates in high-calcium soil. It was evaluated the residual effects of sedimentary phosphates associated with the annual application of phosphate on maize grown in Inceptisol soil with a high exchangeable calcium concentration and... ...
