A method for producing a fertilizer that comprises urea and/or at least one ammonium compound may involve obtaining ammonia as an impurity in the production process, and photocatalytically decomposing the ammonia by irradiation with UV radiation. Further, an apparatus for producing fertilizer granules that comprise urea and/or at least one ammonium compound may include a plant section having a fertilizer granulator configured to produce the fertilizer granules, a supply line configured to pass a urea melt or a concentrated urea solution to the plant section, a UV lamp arrangement that is proximate the supply line and is configured to irradiate with UV radiation the urea melt or the concentrated urea solution flowing in the supply line.

The present invention is an adjuvant for use as an isolate suspension that is used to enhance various agrochemicals such as fertilizers, plant growth formulae, fungicides, insecticides, and herbicides. The adjuvant is derived from a cereal or legume and enhances active ingredients in the agrochemical by creating more absorption surface area per droplet, and increases optimum chemical penetration into the leaf stoma due to the complex protein relationship upon deposition.

The presently disclosed subject matter is directed to nitrapyrin complexes and mixtures as well as syntheses thereof finding particular utility in agricultural uses. For example, these complexes or mixtures can be directly applied to soil, or can be applied in combination with fertilizers to increase nutrient uptake and to inhibit nitrification and urease hydrolysis. More particularly, the subject matter is directed to nitrapyrin complexed or mixed with monoacids that can be further functionalized. Other uses of the nitrapyrin complexes and mixtures, and compositions containing the nitrapyrin complexes and mixtures are disclosed.

A urea cycle augmenting composition for improving plant growth and yields and quality of crops includes a urea cycle augmenting composition, which comprises two or more of L-arginine, L-ornithine, L-aspartic acid, L-citrulline, L-argininosuccinic acid, and agmatine, or salts or derivatives thereof. An amount of the composition applied to a seed or a plant is sufficient to augment the urea cycle of a plant growing from the seed or the plant.

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.
