Weather Extremes Threaten Nitrogen Loss

Kelly MarshallAgribusiness, Nitrogen, Nutrient Management

It’s either too wet or too dry and any farmer can tell you there’s rarely a happy medium, which is why Verdesian Life Sciences is offering advise on getting the most out of your nitrogen investment despite weather conditions.

Often the first challenge is wet weather that prevents growers from getting into the field for pre-plant, top dress or sidedress applications, but even once you’ve gotten into the field there are still challenges. Weather that’s too wet or too dry can cause lose of nitrogen through denitrification, leaching, and volatilization. “Farmers should take steps to protect their applied N from loss to the environment,” says Darin Lickfeldt, Ph.D., senior technical development manager for Verdesian Life Sciences.

Practices that help prevent nitrogen lose include the 4Rs of Nutrient Stewardship, applying the right product at the right rate at the right time in the right place. When those steps fail growers may need to include a nitrogen fertilizer manager or stabilizer, like NutriSphere-N Nitrogen Fertilizer Manager. More than 500 trials of the product have shown a 90 precent positive yield response in corn over the control, and NutriSphere-N has been proven over the course of 10 years on 46 million acres.
