When managing fertilizer, the when of application can matter almost as much as the rate, especially when it comes to nitrogen and minimizing losses, says Peter “Wheat Pete” Johnson.
In this episode of Wheat Pete’s Word, Johnson shares insights into preventing nitrogen fertilizer losses, assessing manure’s nutrient release potential and impact on microbial activity, and why farmers should get going on applying for funding.

Summary
- Has spring sprung?
- The maple sap is starting to run in the deep south
- When things are stormy and cold, it’s amazing what a few days of sun and warmth can do for the outlook
- Heavy snow in some areas doesn’t always mean heavy snow cover
- Book suggestions? Pete’s got them
- Manure management is tough, y’all. Tested, as applied, not always delivers, but also delivers in the long term
- Manure meetings registration
- Can we measure soil microbial activity at opportune time?
- More money available through grants, such as OFCAF. Get the info and apply! There are so many programs out there
- Field PROPHET not profit, but the app lost support and disappeared
- Barley Bill vs Wheat Pete
- Soybeans, nitrogen and water risk — whoa whoa whoa, slow down a minute!
- Link to corn and nitrogen research in Minnesota
- Spring applied nitrogen is virtually always better than fall applied nitrogen (not the norm for the west)
- Nine to 34 bushel gain!
- Split nitrogen application is always better on sand soils
- Drained soil in a wet year will always yield more, lose less nitrogen and result in better nitrogen use efficiency
- When to use an enhanced efficiency fertilizer? If you have a cation exchange capacity of 25 or higher, your risk of volatilization drops significantly, but consider pH too
- Is the cost of ESN worth it?
- Corn doesn’t have surface feeder roots, so it needs phosphorus early
- Taking rye in the spring, and planning back to corn for silage, do you have to spray out the rye? Planting corn after cereal rye is really, really hard.
