A process for preparing humic-mineral agent granules is disclosed. Such a process may comprise providing a humic acid-containing material; crushing the humic acid-containing material to obtain first granules; contacting a quantity of water with the first granules, thereby forming slightly wet granules; blending the slightly wet granules for a period of time, thereby forming blended granules; contacting an amount of alkali with the blended granules, thereby forming alkali-treated granules; and mixing the alkali-treated granules at a temperature high enough to melt organic carbon substances in the alkali-treated granules. The resulting product has biologically, geologically, and chemically active properties, and may be applied to the soil alone or in combination with a commercially available fertilizer. Additionally, the resulting product may be used to detoxify solid or liquid waste products.

A dry and solid fertiliser in the form of discreet particles is provided. The particles of the dry and solid fertiliser comprise a homogenous mixture of organic and inorganic materials. The inorganic material comprises at least one of the NPKS nutrients. The organic material comprises a carbon-labile substantially sterile product of organic waste.

The present disclosure relates to methods of treating water to remove contaminants, including harmful metal ions, and water treatment plants for practicing such methods. In an embodiment, the process includes adding a sulfur-containing, metal-decreasing agent; an iron (III)-containing, metalloid-decreasing agent; forming a solid precipitate from the contaminated water, wherein the solid precipitate includes a solid metal sulfide, a solid iron metalloid, a solid calcium metalloid, or a combination thereof; and separating the contaminated water from the solid precipitate to form purified water.

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.
