Abstract
Water-soluble polyorganic acids having a molecular size of more than 1,500 Daltons enhance plant fertilizer uptake when supplied to the plant, usually in the root feeding zone or through foliar mechanisms. Particularly suitable for this purpose are the polyamino acids such as polyaspartic acid and copolymers thereof.
