A fertilizer system for the long-term fertilization of a crop through use of fertilizer pellets or mats comprised of a fertilizer and thermoplastic polymer blend. The fertilizer system generally includes forming a fertilizer containing polymer comprised of a fertilizer substance and a polymer product. The fertilizer containing polymer is buried within a growing medium and seed is planted over the fertilizer containing polymer. The polymer product within fertilizer containing polymer slowly biodegrades causing the fertilizer substance to slowly release within the growing medium and fertilize the planted seed. The fertilizer containing polymer is formed to continue to biodegrade over a period of several years during which time fertilizer substance will continue to be released. A method of forming the fertilizer containing polymer is also disclosed herein. |
