Abstract
This invention presents a method of making a rigid unitary fertilizer composite for fertilizing plants and trees and articles produced by the method. In the form of a spike, the composite has sufficient strength and toughness so as to enable it to be pushed or pounded into the ground near the roots of plants and trees. The method involves making an aqueous paste containing plant nutrients, acrylamide, and a catalyst for the polymerization of the acrylamide. The paste is then molded to the desired shape. The acrylamide is allowed to polymerize, after which time the excess water is removed by drying. The final product, which should contain at least 5 weight percent polyacrylamide, is a rigid mass.
