    摘要: An agricultural or horticultural fertilizer, and method of making the fertilizer, featuring processed montmorillonite clay and other ingredients for improving plant growth and health. Liquid fertilizers for use in drip irrigation may comprise potash in an aqueous blend, as well as citric acid and humate. The method involves the preparation of a montmorillonite mineral-humate solution, which solution is mixed with other ingredients. In an early step, the montmorillonite and the humate are mixed with water and citric acid, and then blended or mixed over a period of time sufficient for the citric acid to leach the montmorillonite and humate into solution. The solution is then filtered to remove solid mineral residue. The filtered solution is then mixed with Aloe vera and potash to prepare a concentrated liquid.

    摘要: The present technology relates to a method for preparing a mixture of solid potassium salts from a fermentation juice from a fermentation process for the production of chemical compounds in a pH-controlled fermentation medium by adding of a base comprising potassium hydroxide. The method comprises adding an acid to the fermentation juice in an amount sufficient to cause the precipitation of the mixture of potassium salts, and then separating the mixture of salts of potassium solid potassium acidified fermentation juice. The present technology also relates to the mixture of potassium salts obtained by said method and its use as fertilizer.

    摘要: 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.
