    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.

    摘要: The invention relates to compositions for retaining soil moisture and improving plant growth in dry soils, which, together with one or more moisture retaining materials and wetting agents, comprises iron(III)oxides and optionally potassium metabisulfite [borken (HU), E224] as potentiating agent. The iron(III)oxides preferably are microparticulate. The composition suitably comprises iron(III)oxides and potassium metabisulfite as potentiating agent. Other aspects of the invention relate to binding the moisture content of soils, as well as compositions for use in enhancing the efficacy of soil retaining compositions.

    摘要: The uptake of foliar-applied metal ion nutrients, for example, zinc, iron, magnesium and copper, is influenced by humidity. Specifically, uptake is negatively impacted if the zinc is applied under low humidity, as the metal ion is “locked up” by leaf waxes as the droplet dries on the surface of the leaf, thereby rendering the metal ion useless. Described herein is a foliar metal ion fertilizer comprising (a) a metal ion sulphate in combination with a mixture of (b) urea and (c) a substance with a suitable point of deliquescence (POD) such as organic surfactants, calcium chloride, magnesium chloride or combinations thereof.
