Agglomerated dispersible granules, methods for amending soil, and activated alumina suspensions

An activated alumina suspension, comprising:

• activated alumina particles having:
• a porous structure;
• a plurality of electrically-charged binding sites disposed within the porous structure;
• and
• a particle size measured by largest particle dimension less than 200 μm;
• and
• a continuous phase,
• wherein the activated alumina particles constitute a dispersed phase suspended in the continuous phase.

A method for amending soil with buffered phosphorus, comprising:

• physically blending activated alumina particles with phosphate particles, the activated alumina particles having:
• a porous structure;
• and
• a plurality of electrically-charged binding sites disposed within the porous structure;
• and then
• agglomerating the alumina particles with the phosphate particles to form agglomerated dispersible granules;
• and
• applying the agglomerated dispersible granules to soil,
• wherein the activated alumina particles and the phosphate particles are present in the agglomerated dispersible granules as distinct phases agglomerated together and the activated alumina particles are free of phosphate disposed within the porous structure when applied to the soil.

Agglomerated dispersible granules, comprising:

• 10-80%, by weight, activated alumina particles having:
• a porous structure;
• and
• a plurality of electrically-charged binding sites disposed within the porous structure;
• 10-80%, by weight, phosphate particles;
• and
• 10-50%, by weight, water-soluble binder,
• wherein the activated alumina particles and the phosphate particles are present in the agglomerated dispersible granules as distinct phases agglomerated together.

Agglomerated dispersible granules, comprising:

• activated alumina particles having:
• a porous structure;
• and
• a plurality of electrically-charged binding sites disposed within the porous structure;
• and
• phosphate particles,
• wherein the activated alumina particles and the phosphate particles are present in the agglomerated dispersible granules as distinct phases agglomerated together, and
• wherein:
• the agglomerated dispersible granules are coated with:
• an additional nutrient layer, the additional nutrient layer including at least one nutrient selected from the group consisting of bioavailable species of molybdenum, selenium, zinc, copper, cobalt, iron, nickel, manganese, vanadium, calcium, potassium, sulfur, chlorine, silicon, magnesium, sodium, nitrogen, boron, and combinations thereof;
• or
• a pesticide layer;
• or
• a biological additive layer, the biological additive layer including at least one additive selected from the group consisting of humics, fulvics, living microbes, microbial metabolites, plant extracts, exogenous plant hormones, and combinations thereof, or
• combinations thereof, or
• the agglomerated dispersible granules further include biological additive particles present as distinct phases and agglomerated with the activated alumina particles and the phosphate particles wherein the biological additive particles include at least one additive selected from the group consisting of humics, fulvics, living microbes, microbial metabolites, plant extracts, exogenous plant hormones, and combinations thereof;
• or
• combinations thereof.
