ABSTRACT:
This invention relates to enhancing plant productivity employing a method and improved compositions containing water-soluble crosslinked polyamino acids having a weight average molecular weight of a size larger than about 1,500. More particularly, crosslinked polyamino acids enhance plant productivity when supplied to the plant directly as the free acid or salt thereof or hydrolyzed from a crosslinked precursor of the crosslinked polyamino acid by the method disclosed. Particularly suitable for this purpose are water-soluble, crosslinked polyaspartic acid, and salts thereof and hydrolyzed crosslinked polysuccinimide.
