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.

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.

A method for decomposing struvite comprises dissolving of a feed material comprising struvite in a mineral acid. Thereby a solution having an acid pH is formed. Magnesium is removed from the solution. The removing of magnesium comprises increasing a pH of the solution to a pH in the range of 4.5 to 6, precipitating magnesium compounds that do not comprise ammonium, and separating the precipitated magnesium compounds from the solution. Thereby, the solution, after the removing of magnesium, comprises an ammonium salt of the mineral acid. An arrangement for performing such a method is also disclosed. Also, a method and arrangement for recovering at least nitrogen from waste material, based on the decomposing of struvite are disclosed.

The present invention relates to mixtures comprising a carrier A comprising a compound I (first nitrification inhibitor) and a carrier B optionally comprising a compound II (second nitrification inhibitor), wherein the compound I (first nitrification inhibitor) and the compound II (second nitrification inhibitor) are both selected from the group consisting of different nitrification inhibitors; to a method for improving the nitrification-inhibiting effect, or for increasing the health of a plant using mixtures of one compound I and one compound II; to the use of mixtures comprising compounds I and compounds II for increasing the health of a plant; to agrochemical compositions comprising these mixtures; and to plant propagation material, comprising these mixtures or these agrochemical compositions. The present invention especially relates to mixtures comprising DMPSA and DMP/DMPP.
