Abstract: Fertilizer granules containing elemental sulfur and a hydrogel which expands or swells in the soil to more readily disperse the elemental sulfur surface throughout the soil, which increases the elemental sulfur surface area available for oxidation, and ultimately uptake of sulfur by the plant. The elemental sulfur and hydrogel can be added to a fertilizer composition as either an exterior coating or co-granulated with the base fertilizer composition.

Abstract: In one aspect, a multi-layered fertilizer includes a layer-by-layer coated fertilizer layer and a coating layer, wherein the fertilizer layer is separated from the coating layer, and one of the fertilizer layers is a fertilizer core; the fertilizer layer contains at least one of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer, the coating layer is polyurea formaldehyde, which includes at least a polyurea formaldehyde having two to five carbon atoms. It can better control the release of nitrogen, phosphorus, potassium, calcium, magnesium and zinc in the fertilizer to meet the different nutrient requirements of different crops at different growth stages. The fertilizer can be prepared by a reactor, a slurry tank, a powdering tank and supporting facilities, which can control the amount of each layer of fertilizer and its position in the entire fertilizer granules according to a design procedure.
