New Nitrogen Stabilization Options with Maleic Itaconic Acid Copolymer Formulations.

Maleic Itaconic Acid Copolymer (MIAC), which is commercialized under the trade name NutriSphere-N®, has been commercialized for >10 years, its been used on >80M hectares, and >85% of growers who use MAIC, have used it again in the subsequent year. This unique N stabilization chemistry has been shown to increase grain yield in corn and wheat by stablizing N against volatilization and leaching losses. Historically, growers had the option for either treating dry fertilizers such as urea or liquid fertilizers such as UAN with MAIC. Two new formulations have recently been commercialized. The first of these is NutriSphere-HV® (high volume) and its used to stabilize N applied in high volume liquid applications (>280 L/ha). The other new formulation is NutriSphere-NH3® and its injected concurrently with anhydrous ammonia using advanced injection equipment. Growers now have options for stabilizing all popular forms of N fertilizer with MAIC, thereby generating greater yield and improving environmental sustainability by reducing N loss. Data from replicated field trials will be presented.
