Evaluation of Urea Nitrogen Fertilizer Treated with Nutrisphere Polymer Additive to Increase Fertilizer Efficiency

The use of polymer additives to regular soluble fertilizers has been shown to increase the uptake of fertilizer nutrients into target crops. The mechanism of activity of the polymers is thought to slow down the reaction of the fertilizer nutrient ions and molecules with various soil compounds. The Nutrisphere polymer additive is added to urea or urea containing nitrogen fertilizers.
