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.

This invention relates to polymer-based partially-open, hollow reservoirs in the nano-size to micro-size range that encapsulate an additive, which can be released from the reservoirs using specific event stimuli such as reduction-oxidation and voltage change, or at will, using the same stimuli. This invention also relates to method preparing such reservoirs, and for releasing the additive. This invention further relates to matrix that comprises such reservoirs and the method of preparing such matrix. This invention also relates to applications, for example in corrosion inhibition, lubrication, and adhesion, that benefit from using such a controlled release of an additive.

A method for continuous production of fully colored and non-colored fertilizer particles having a median size of about 1 to 6 mm, with a predefined ratio of the fully colored and non-colored fertilizer particles, starting from a stream A of non-colored fertilizer particles. The method includes continuously separating the stream A of non-colored fertilizer particles into a stream C of non-colored fertilizer particles and parallel streams B1, B2, . . . Bn of non-colored fertilizer particles in a predefined ratio, continuously coloring the non-colored particles from the parallel streams B1, B2, . . . Bn with a non-rub-off coloring agent, such that the particles become fully colored, continuously joining the parallel streams B1, B2, . . . Bn, including the fully colored fertilizer particles, with the stream C of non-colored fertilizer particles downstream, thereby obtaining the mixture of fully colored and non-colored fertilizer particles, and, optionally, processing the mixture of fully colored and non-colored fertilizer particles.
