Take a Closer Look at Nitrogen Leaching

No matter the size of your customers’ farms, fertilizer will be one of their largest input investments each season. However, spring rains and warm soil temperatures can lead to leaching and denitrification. And with those nitrogen losses, the loss of corn yield potential — and profit — might not be far behind.

Watch Mike Koenigs, nutrient maximizer development specialist for Corteva Agriscience, demonstrate how leaching occurs using an experiment known as the leach tube test. In the experiment, Koenigs uses charged dyes to show how different types of nitrogen behave in the soil. The positively charged dye represents ammonium, which is relatively immobile in the soil. the negatively charged dye represents nitrate, which is mobile in the soil and vulnerable to loss.

This experiment also illustrates how N-Serve® and Instinct NXTGEN® nitrogen stabilizers, powered by Optinyte® technology, reduce nitrogen leaching. Optinyte does this by slowing the conversion of ammonium to nitrate, preventing loss and extending nitrogen availability in the corn root zone for up to eight additional weeks, compared to two weeks of control provided by competitor products. This helps ensure nitrogen is there when corn needs it, during key growth stages, to maximize yield potential.

In fact, Optinyte reduces leaching by 16% and increases average corn yield by 7% when used with fall nitrogen applications and by 5.2% when used with spring applications.1 The bottom line: N-Serve and Instinct NXTGEN provide proven benefits to, both, the environment and your customers’ ROI.
