The present invention provides a fertilizer utilizing the inexpensive waste and by-product materials of biosolids, gypsum, and/or other phosphorus binding agents, such as iron or aluminum chemicals or by-products with elevated levels of iron and aluminum. The combination of biosolids, gypsum and other phosphorus binding agents, such as iron or aluminum chemicals or by-products with elevated levels of iron and aluminum produces a fertilizer that provides for soil nitrogen needs while limiting the availability of phosphorous to minimize environmental pollution.
