摘要： A method for applying an agricultural fertilizer to a field through an irrigation system connected to a source of hard water, includes providing a fertilizer composition comprising a mixture of (i) a fertilizer component comprising an ammonium phosphate or an ammonium sulfate, and (ii) an acid comprising one or more of a phosphoric acid, a citric acid, a malic acid, a formic acid, and an oxalic acid; combining the fertilizer composition with hard water from the hard water source and providing the mixture to an irrigation system; and using the irrigation system to apply the mixture of fertilizer composition and hard water to the field.

摘要： A plant fertilizer composition that includes an acid whereby said acid may react with, chelate, or block any metal ions in the soil in which the plants grow during administration of the fertilizer. This reaction renders the metal ions substantially ineffective for reacting with the fertilizer components. The fertilizer is thereby shielded from interference with any metal ions in the soil and the delivery of the fertilizer to the plant roots is thereby enhanced. The acid may be, but is not limited to, an organic acid and is preferably citric acid. The fertilizer composition may include phosphorus. Likes in one embodiment, the fertilizer composition may include phosphate ions and citric acid, the citric acid chelating any metal ions in the soil in which the plants grow thereby facilitating the transportation of phosphate to the plant roots. The invention further discloses a method for providing a fertilizer to plant roots, comprising the steps of administering to the soil in which the plants grow, a plant soil fertilizer composition; and shielding the fertilizer from interference with any metal ions in the soil in which the plan grow during said administration of the fertilizer to the plant roots, thereby enhancing delivery of the fertilizer to the plant roots.
摘要翻译： 植物肥料组合物，其包含酸，由此所述酸可以在施用施肥期间植物生长的土壤中与之反应，螯合或阻断任何金属离子。 该反应使得金属离子对于与肥料组分反应基本上无效。 因此，肥料可以防止土壤中任何金属离子的干扰，从而提高肥料向植物根部的传递。 酸可以是但不限于有机酸，并且优选是柠檬酸。 肥料组合物可以包括磷。 喜欢在一个实施方案中，肥料组合物可以包括磷酸根离子和柠檬酸，柠檬酸螯合植物生长在其中的土壤中的任何金属离子，从而便于将磷酸盐输送到植物根部。 本发明还公开了一种向植物根提供肥料的方法，包括对植物生长的土壤施用植物土壤肥料组合物的步骤; 并且在肥料施用于植物根部期间，屏蔽肥料免受计划生长的土壤中的任何金属离子的干扰，从而增强肥料向植物根部的输送。
