A concentrated aqueous composition of microfibrillated cellulose (MFC) comprising salts for plant nutrition. The concentrated aqueous composition comprises microfibrillated linear polymers of D-glucose molecules (cellulose microfibers), calcium ions, sulfate ions and other elements for plant nutrition. The concentration of calcium ions and sulfate ions exceeds the concentration corresponding to the solubility of calcium sulfate in water. The proportion of MFC is within a range of 1% and 99% w/w of the composition, and the precipitation of salts is prevented in a pH range from 1 to 13.

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.
