For many farmers, harvest marks the finish line of another growing season. But some of the most valuable information for next year's crop is gathered during those few weeks spent in the combine, grain cart, or truck. Harvest provides a unique opportunity to evaluate what worked, identify areas for improvement, and collect observations that can directly improve profitability in the year ahead.
The highest-yielding growers are often not just strong crop managers. They are strong record keepers. They use harvest to understand why certain fields excelled while others underperformed and turn those lessons into better decisions next season.
Field averages tell only part of the story. Harvest is a great time to identify which areas consistently delivered the best yields and ask what those acres have in common.
Consider:
Accurate yield data can help reveal field-to-field and within-field patterns that support future decisions on fertility, drainage improvements, variety placement, and input management. Researchers continue to emphasize that quality harvest data is one of the most valuable tools for improving long-term farm profitability.
Low-yielding areas often tell an important story. Harvest is an excellent time to flag locations where yields unexpectedly dropped off.
Potential causes may include:
A simple note made during harvest can help prioritize scouting, soil sampling, drainage projects, or management changes before next spring. Often, these problem areas are easy to identify when harvest equipment is moving through the field but much harder to remember six months later.
Even a quick observation from the combine cab can provide valuable information for future weed management.
University weed specialists recommend recording:
Harvest observations can help identify fields that may require different management strategies, alternative herbicide programs, cover crops, or additional attention in future seasons. Weed escapes that go unnoticed today often become larger and more expensive problems tomorrow.
Every harvest generates real-world variety trial data.
Beyond yield, take note of:
For growers raising food-grade soybeans or yellow field peas, these observations can be especially valuable. The highest-yielding variety is not always the most profitable if quality, standability, or marketability become concerns. Comparing performance across fields and years can help guide future seed decisions.
Yield is important, but quality often determines final profitability.
Take time to note issues such as:
These observations can often be tied back to management decisions, variety selection, fertility programs, disease pressure, harvest timing, or environmental conditions. Understanding these relationships can help improve both yield and marketability in future seasons.
Harvest data is only as good as the information being collected. Extension specialists consistently stress the importance of properly calibrated yield monitors and scales to ensure accurate data collection. Reliable yield records create a stronger foundation for future decisions related to fertility, seeding rates, drainage investments, and field management.
Harvest may be the end of one season, but it is also the starting point for the next. The most valuable observations often come from a notebook, a phone note, or a quick pin dropped on a field map while the crop is still coming off.
At PURIS, we encourage growers to view harvest as more than a yield report. It is an opportunity to capture lessons that can improve future yield potential, crop quality, and profitability. A few minutes spent recording key observations today can help turn this year's experience into next year's success.
