摘要
Agglomerated dispersible granules are disclosed including activated alumina particles and phosphate particles. The activated alumina particles have a porous structure and a plurality of electrically-charged binding sites disposed within the porous structure. The activated alumina particles and the phosphate particles are present in the agglomerated dispersible granules as distinct phases agglomerated together. A method for amending soil with buffered phosphorus is disclosed including physically blending and then agglomerating activated alumina particles with phosphate particles to form the agglomerated dispersible granules. The agglomerated dispersible granules are applied to soil with the activated alumina particles and the phosphate particles being present as distinct phases and the activated alumina particles being free of phosphate disposed within the porous structure. An activated alumina suspension is disclosed including activated alumina particles suspended as a dispersed phase in a continuous phase, the activated alumina particles having a particle size less than 200 µm.
