Activity of phosphorus of synthetic Fe-K-P compounds in superphosphate fertilizers as affected by pH and ionic strength Efeito do pH e da força iônica na atividade de fósforo oriundo de compostos sinteticos do tipo Fe-K-P de superfosfatos

Activity of phosphorus of synthetic Fe-K-P compounds in superphosphate fertilizers as affected by pH and ionic strength Efeito do pH e da força iônica na atividade de fósforo oriundo de compostos sinteticos do tipo Fe-K-P de superfosfatos

The concentration of orthophosphate ions released from Fe-K-P compounds (Fe3KH8(PO4)6 .6H2O and Fe3KH14(PO4)8 .4H2O) present in superphosphates increases with pH, which initially suggests that the agronomic effectiveness of P fertilizers containing high amounts of these compounds would also increase...
