Curb nitrate leaching to support conservation efforts

This summer across the Midwest, corn growers have faced excess rainfall and an increased risk of losing essential nutrients such as nitrogen. Growers can support environmental stewardship by applying a nitrification inhibitor to prevent nitrogen loss and keep nitrogen where it belongs: in the root zone.

Nitrogen can be lost through leaching and denitrification. Fortunately, there are ways growers can prevent nitrogen loss through the responsible application of a nitrification inhibitor.

“Using a nitrification inhibitor keeps more nitrogen available to corn crops at the root zone and reduces leaching of nitrogen into the groundwater,” says Tiffany Dean, nitrogen stabilizers product manager, Dow AgroSciences. “Nitrapyrin is designed to inhibit nitrification and found only in N-Serve and Instinct II nitrogen stabilizers.”

Many states have implemented plans to decrease nitrogen loss through environmentally beneficial farming practices. One example is the Iowa Water Quality Initiative that offers growers a $3 per acre rebate, for up to 160 acres, if they try N-Serve® nitrogen stabilizer for the first time with their fall anhydrous ammonia application.

Along with state initiatives, programs such as the 4R Nutrient Stewardship program encourage growers to implement environmentally sustainable practices. The 4R program is a concept to use the right fertilizer source, at the right rate, at the right time, with the right placement. The 4R framework takes an innovative approach that provides educational tools, advocacy support and implementation recommendations for crop nutrient stewardship.

“We are proud to support conservation programs, such as the 4R program, that recommend management practices to help growers increase production, boost profitability and improve environmental sustainability,” Dean says.
