According to some embodiments, there is provided herein a fertilizer granule comprising Polyhalite and Sulphate of Potash (SOP), wherein the granule comprises a granule strength of at least 0.5 Kg/granule.

The present disclosure is drawn to anti-fungal pelleted blends, such as blends including multiple types of dry pellets homogenously admixed together. Pellets of the blend may include urea source pellets; ammonium source pellets including ammonium sulfate; phosphorus source pellets including an ammonium phosphate compound; and potassium source pellets including potassium chloride, potassium phosphate, potassium nitrate, potassium sulfate, or a combination thereof. The anti-fungal pelleted blend can be from 90 wt % to 100 wt % dissolvable in water at 20° C. within about 3 minutes. The multiple types of dry pellets may provide a total nitrogen content from 15 wt % to about 40 wt %, a total phosphorus content from about 1.8 wt % to about 8.8 wt %, and a total potassium content from about 4.1 wt % to about 16.6 wt %,

A fertilizer comprises a slow release source of phosphorus and a slow release source of sulfur. The slow release source of phosphorus may be struvite. The slow release source of sulfur may be polyhalite. The fertilizer may further contain a fast release source of phosphorus such as a water-soluble phosphorus-containing material. The fertilizer may be in the blended form or in the co-granular form. A number of methods may be used to make such co-granular fertilizers.

The present disclosure concerns fertilizer particles comprising calcium nitrate and potassium nitrate. It is found that fertilizer particles comprising 43 to 47% w/w calcium nitrate and 46 to 54% w/w potassium nitrate can be produced by melt granulation. Due to undercooling problems, such particles were not expected to be suitable for industrial production by melt granulation. However, the present disclosure provides a composition which forms a low viscosity melt with short solidification time. This was successfully achieved by reducing the water content of a fertilizer melt comprising 43 to 47% w/w calcium nitrate and 46 to 54% w/w potassium nitrate to less than 3% w/w of the melt.
