Plant availability of phosphorus in four superphosphate fertilizers varying in water-insoluble phosphate compounds
(SOIL SCI SOC AMER, 2008)
There is concern that the use of lower quality phosphate rock can result in elevated amounts of Fe-Al-P water-insoluble compounds in fertilizers and, consequently, low agronomic effectiveness. Therefore, studies were ...
Sistemas baseados em amido termoplástico: pectina contendo hidroxiapatita nanoestruturada visando liberação de fósforo em meio aquoso
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Biotecnologia, 2013-06-28)
The use of fertilizers to increase agricultural production, combined to the high import rate of this resource by Brazil, has motivated scientific and technological development of high performance fertilizers. In this ...
Filter cake in industrial quality and in the physiological and acid phosphatase activities in cane-plant
Sugarcane filter cake, a phosphorus-rich (P) fertilizer, can affect not only P storage in sugarcane (Saccharum officinarum L.), but also its metabolism and photosynthesis. In this study, was evaluated the effect of different ...
Estratégias para obtenção de compósitos fertilizantes via solubilização biológica de minerais
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Engenharia QuímicaCâmpus São Carlos, 2018-03-27)
Phosphate fertilizers are widely used to improve agricultural productivity. However, the process of producing these fertilizers involves high costs and can cause environmental damage. The application of phosphate solubilising ...
