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.

The present invention relates to a process for preparing a formulation F for reducing nitrification. The present invention also relates to a formulation F obtainable by the process of the invention. Furthermore, the present invention relates to a process of preparing a fertilizer-nitrification inhibitor mixture, and to a fertilizer-nitrification inhibitor mixture obtainable by this process. Moreover, the present invention relates to a method of fertilizing agricultural soil.

The invention is a coating for agricultural products, which includes at least 10% of renewably sourced and biodegradable sugar esters. The invention is also a method of making a coated agricultural product, including the steps of providing a coating composition comprising at least 10% of a renewably sourced and biodegradable sugar ester, heating the coating composition to a temperature to reduce its viscosity to below about 100 cP, adding the coating composition to an agricultural product to form a mixture, and cooling the mixture to produce a coated agricultural product. The invention is also a method of reducing dust released from an agricultural product that includes the step of providing a coating composition comprising at least 10% of a renewable sourced and biodegradable sugar ester. Enough of the coating composition is added to the agricultural product to reduce the amount of dust released from the agricultural product by at least half. Finally, the invention is also a method of reducing caking in a granular agricultural product.

Methods, systems, and apparatuses for coating a material by contacting the material with a coating material and a solvent are disclosed herein. The coated material can be obtained by evaporating the solvent: by heating the coated material directly or indirectly with electromagnetic radiation; by heating with heat generated from a heat source that heats an internal container for the material to be coated and/or coated material; and/or in an interior volume of a coating container having a side wall, by heating a portion of the side wall of the coating container and/or internal container with a heat source that is positioned outside of the interior volume of the coating container.

This invention relates to a method for the manufacture of a homogeneous, solid, particulate, urea-based material comprising elemental sulphur. The invention further relates to a homogeneous, solid, particulate urea-based material comprising small elemental sulphur phases in a urea-based base material and formed by an accretion process. The product is in particular suitable as a fertilizer.

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 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.
