Fertilizer with Polyamine Additive for Use In Irrigation Environments
The present development is a composition for a commercial fertilizer product that provides for nitrogen, phosphate and/or potassium availability to the plant even in a hostile growing environment with hard water sources. The fertilizer of the present invention includes a polyamine additive, water, and soluble nitrogen, potassium, and/or phosphate, that are essentially unaffected by hard water thereby retaining their availability to the target plants.
