Fine-Tuning Fertilizer Programs for Maximum Yield

As farmers prepare for the 2027 corn season, they're facing uncertainty about input costs. One area where efficiency can be improved is in nitrogen usage.

To gain a better understanding of nitrogen efficiency on their farms, experts recommend pulling random stalk samples after the black layer stage and sending them for analysis.

This will provide data on how much extra nitrogen was available but not used by the ear. This information can help farmers make informed decisions about nitrogen usage in 2027, even if the field won't be planted with corn next year.

Additionally, researchers suggest looking at soil organic matter levels and the availability of nutrients like sulfur, which can impact nitrogen use by plants.

Fine-tuning fertilizer inputs is crucial to maximizing yields while minimizing costs. By applying nitrogen when the plant needs it, farmers can optimize their fertility program and reduce waste.
