Abstract: Methods and system for increasing the water solubility and availability of zinc in granular fertilizers using acid treatments. The treatment of granular fertilizers with an acidic solution increases an amount of water-soluble zinc, which in turn, increases the efficiency of zinc uptake and reduces the costs and equipment otherwise needed to mitigate zinc deficiencies.

Abstract: An oil-based coating for fertilizer granules impregnated with a polymer additive and related methods of applying the oil-based coating. The polymer additive can comprise homopolymers, copolymers, or combinations thereof, including polyethylene homopolymers. The polymer additive increases the viscosity of the oil-based coating, thereby increasing the duration for which the coating is capable of controlling or inhibiting the formation of dust particulates from the fertilizer granules.

Abstract: A fertilizer composition including a base fertilizer granule with a barrier coating and one or more micronutrients. The base fertilizer material is coated with a barrier coating, and then a coating of one or more micronutrients. Alternatively, the base fertilizer material is coated with a barrier coating having discrete particles of micronutrients dispersed throughout. The barrier coating acts to physically and chemically isolate the micronutrient particles from the underlying fertilizer composition such that more of the micronutrient is available to the soil solution, and ultimately to the root zone of the plant.

Abstract: A method of producing a granulated and compacted fertilizer having incorporated micronutrients in which the granulated primary nutrient and micronutrients are mixed at smaller particle sizes before being compacted into a larger, easier to handle particle sizes.

Abstract: A granulated fertilizer having a primary nutrient and a micronutrient and related methods of making. The micronutrient is incorporated into the fertilizer mixture by dissolving a compound form of the micronutrient into a feed stream for the formulation of the fertilizer material, a water return stream for the scrubbing of waste gas, and/or a feed stream for back titration of the fertilizer material.

Abstract: A granulated phosphate composition that provides sufficient nutritional value as well as enhanced pelleting benefits, such as abrasiveness and lubricity, compared to other granulated phosphate feed products. The granulated phosphate composition includes a phosphate source, such as monocalcium phosphate, mono-dicalcium phosphate, or dicalcium phosphate, and one or more additives such as lubricity and abrasivity additives. The lubricity additive can include a sodium additive that lubricates the die during a feed milling or pelleting process. The abrasivity additive can include silica or sand that scours the die during the pelleting process. The increased lubricity and abrasivity attributes of the composition benefits die throughput and efficiency in the pelleting process, without compromising nutritional value in the final feed product.

Abstract: According to a method of producing a phosphate fertilizer, a first portion of the phosphate is produced in a pipe cross reactor, and a second portion of the phosphate is produced in a pre-neutralizer. Both the first and second portions of the phosphate are supplied to a granulator. Ammonia is added to the granulator to react with the first and second portions of the phosphate. To produce the first portion of the phosphate, a micronutrient is added to phosphoric acid to produce an enriched acid, and the enriched acid and ammonia are added to the pipe cross reactor where they are allowed to react to produce ammonium phosphate.

Abstract: Phosphate rock is reacted with phosphoric acid to produce monobasic calcium phosphate. Monobasic calcium phosphate is reacted with ammonium carbonate to produce ammonium phosphate. Dibasic calcium phosphate is also produced as a by-product when monobasic calcium phosphate reacting with ammonium carbonate. The dibasic calcium phosphate is reacted with sulfuric acid to produce phosphoric acid. The phosphoric acid is used to react with phosphate rock. Ammonium sulfate or ammonium hydroxide may be used instead of ammonium carbonate. Phosphate other than ammonium phosphate can be produced if calcium phosphate is reacted with x-y to produce x-phosphate, where x is lithium, sodium, ammonium or potassium and y is carbonate, bicarbonate hydroxide or sulfate.
