    摘要： The invention relates to a process for producing a controlled release fertilizer of potassium chloride comprising the following steps: a. providing compacted KCl, having a sphericity of below 0.87; b. dry polishing the KCl in an intensive mixer type device consisting of a container vessel and at least one set of agitating elements such that the KCl has a sphericity of between 0.88 and 0.92; c. providing a coating on said polished KCl. The polished and coated compacted KCl can show with 6 pph coating a release of about 18% after 7 days measured with a water leach test at 21 C. The polished and coated compacted KCl may have one or more of the following release properties: a release at 10 days of about 20% or less; and/or a release at 30 days of 40% or less; and/or a release at 50 days of 50% or less.

    摘要： An organic fertilizer/plant food containing molasses to increase microorganism activity in soils. The molasses provides additional nutrients to the soil that are readily available for plant intake. The molasses provides sugars to increase microorganism activity to benefit soil structure before the slower process of microorganism break-down of other organic materials can occur. The molasses may be applied to the fertilizer mixture in various ways including by spraying.

    摘要： It is described an integrated process for the production of clinker by dry process, with treatment in continuous of by-pass dusts produced by the kiln, wherein the solid matter to treat consists of bypass dusts of a clinker production process, containing compounds of chloride, sodium, potassium and sulphur, such a process comprising the following steps: a) extraction of the bypass dusts directly from the phase of quench, without intermediate storage, at a temperature comprised between 150 and 200° C., with a moisture content varying from 0.1 to 3% by weight, preferably from 0.1 to 0.5% by weight, and with a quantity of calcium carbonate lower than 55% by weight; b) mixing of said dusts coming from step a), within a maximum time comprised between 2 and 10 minutes, preferably lower than about 5 minutes, with water up to a water/dusts ratio varying from 2:1 to 4:1, preferably from 2.5:1 to 3.5:1, in a way to obtain a mixture with a moisture content comprised between 45 and 75% by weight, preferably between 50% and 55% by weight, even more preferably equal to about 50% by weight; c) mechanical stirring of the mixture diluted up to complete dissolution of the soluble salts; d) mechanical separation of the mixture so diluted in a liquid fraction containing water and soluble salts and in a solid fraction in form of cake or crust.

    摘要： A dry, flowable fertilizer is provided that includes multiple dry, flowable biosolids pellets. Each of the pellets has a pellet surface. Potassium salt grains are adhered to the pellet surfaces and a dust control agent coating is applied to retain the grains on the pellet surfaces. The resultant dry, flowable fertilizer has higher potassium loadings to the potassium salt grains than previous biosolids based fertilizers. A process of forming a fertilizer is also provided that includes tumbling dry, flowable biosolids pellets with powdered potassium salt grains to form a mixture. An aqueous spray is added to adhere the salt grains to the pellet surfaces. With the application of a dust control agent, the salt grains are retained. Potassium levels in NPK units of from 1 to 15 are routinely achieved with greater than 90 elemental % of the potassium is from the surface decorating potassium salt grains.
