Fertilizer liquid compositions comprising an aqueous solution of nitrogen, phosphorus and potassium macronutrient components are disclosed. The nitrogen is provided by a water-soluble urea-formaldehyde reaction product which is absorbed at about the same rate as other macronutrient components present in the fertilizer composition. The compositions of the present invention avoid phytotoxicity and metabolic imbalance in plants and provide for healthy plants with increased yields and a highly efficient utilization of nutrients when used either alone or in combination with other micronutrients, in foliar feeding of field crops such as legume and cereal grain crops and in turf care, horticulture and silviculture.
本发明公开了由氮、磷和钾等主要营养成分的水溶液组成的液态肥料组合物。氮由水溶性脲醛反应产物提供,其吸收率与肥料组合物中的其他主要营养成分大致相同。本发明的组合物可以避免植物的植物毒性和代谢失衡,在单独使用或与其它微量营养元素结合使用时,可使植物健康,产量提高,养分利用率高,可用于大田作物(如豆类和谷类作物)的叶面施肥,也可用于草坪护理、园艺和造林。
