Those who apply nitrogen fertilizer in the fall generally understand that the nitrification process (a.k.a., the process that contributes to nitrogen loss), is chemically halted when the weather gets cold enough and then begins again as temperatures rise.
However, gaining a deeper knowledge of what happens to fall-applied nitrogen over the winter and into spring can make you better prepared to make the best nitrogen management recommendations for your customers year-round.
With that in mind, here are a few key takeaways to understand about fall-applied nitrogen as it hibernates over the winter:
Fall-applied nitrogen is a fantastic way to prepare fields for the coming year and can help alleviate some of the workload in spring. But, science shows us that nitrogen is vulnerable to loss from the moment it is applied. To get the benefits of fall-applied nitrogen but ensure it’s there for your crops come spring, it’s best to protect it with a proven nitrogen stabilizer, like N‑Serve®.
N‑Serve protects nitrogen from leaching and denitrification, so it’s guarded during the warm and wet transitional weather periods. N‑Serve also extends nitrogen’s availability in the soil so that it’s there in the spring when your crops need it during critical growth periods.

Do not fall-apply anhydrous ammonia south of Highway 16 in the state of Illinois. Always read and follow label directions.
