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.

Provided is a solvent borne fertilizer composition. The fertilizer composition includes a low molecular weight lignin in an amount of 5 or about 5 to 25 or about 25 weight percent solids, a carbohydrate in an amount of 1 or about 1 to 20 or about 20 weight percent solids, wherein the lignin and carbohydrate form a lignin-carbohydrate mixture; and a urea moiety bonded to the lignin-carbohydrate mixture.

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.
