The invention relates to a particulate urea-based blend composition comprising a urea-based compound in particulate form and one or more components in particulate form, selected from the group of nitrates, phosphates, sulphates and chlorides, and a urease inhibitor of the type phosphoric triamide, and a magnesium sulphate, wherein the urea-based blend composition is further characterized in that it comprises an alkaline or alkaline-forming compound, selected from the group of calcium oxide, zinc oxide, magnesium oxide, calcium carbonate, and mixtures thereof. The composition according to the invention has improved properties for reducing ammonia loss by urease activity in the soil and is in particular suitable as a fertilizer. The invention further relates to a method for the manufacture of said urea-based blend composition, as well as to a composition of kit of parts comprising an amount of a) magnesium sulphate; b) a urease inhibitor of the type phosphoric triamide, preferably N-(n-butyl) thiophosphoric triamide (nBTPT); c) an alkaline or alkaline-forming compound, selected from the group of calcium oxide, zinc oxide, magnesium oxide, calcium carbonate, and mixtures thereof, and d) optionally, one or more anti-caking and/or moisture-repellent and/or anti-dust compounds.

A fertilizer coating providing effective dust control and caking reduction properties while maintaining organic farming standards. The coating may comprise a combination of highly saturated triglycerides, such as palm stearin, and plant-based oil and/or lecithin, such as soybean oil and/or soy lecithin. The coating may further comprise gum derived from plants, such as fenugreek gum.

A system and method are provided for manufacturing the polymer-coated fertilizers with a controlled release in a single pass. The system has a feeding mechanism connected to a first chill roll to supply the articles to the first cavities provided on the first roll to store and hold the articles. A first machine produces and applies a first polymer film on the articles held in the first chill roll to coat the articles partially with the first polymer film. The partially coated articles are transferred to a second chill roll placed at a side or on a top of the first chill roll. A second machine produces and applies the second polymer film on the partially coated articles in the second chill roll so that the articles are encapsulated by the first and second polymer films. A collector mechanism receives the encapsulated articles from the second chill roll.

A fertilizer coating that provides nutrients and/or biostimulants, as well as added dust control and caking control. The fertilizer coating may comprise a carrier, one or more micronutrient dispersants, and/or one or more micronutrients. The carrier may be aqueous-based or oil based. The coating may further comprise one or more biostimulants in an aqueous media.

The disclosure relates to fertilizer coating compositions and methods for making thereof. The fertilizer coating comprises a decarboxylated rosin acid (DCR) component, optional bitumen and other additives. The DCR has a Kb value of 25-90, a density of 0.9 to 1.0 g/cm.sup.3 at 20° C., an aniline point of 3-40° C., and an acid value of <50 mg KOH/g. The fertilizer coated with the coating composition has a reduction in dust level of >25% after 2 weeks of aging compared to a fertilizer not having the coating composition disposed thereon, according to Dust Level Measurement Test.
