Disclosed herein is a fertilizer composition including a plant nutrient comprising a phosphorus compound; and an inorganic acidic compound free of phosphorus. The fertiliser composition can also comprise a fertilizer granule and a coating disposed on the fertilizer granule wherein the fertilizer granule comprises a plant nutrient; and the coating comprises sulfuric acid, nitric acid, hydrochloric acid, or a combination. The plant nutrient comprises a phosphorus compound. The fertilizer composition is useful in fertigation.

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.

A fertilizer comprises an intermediate-release source of phosphorus. The intermediate-source of phosphorus may be schertelite. In one embodiment, the intermediate-source of phosphorus may consist substantially all of the phosphorous content in the fertilizer. In other embodiments, the fertilizer further comprises one or both of a slow-release and fast-release source of phosphorus. The fertilizer may be in the form of a homogenous prill. A number of methods may be used to make such fertilizers.
