With melted snow and warmer weather in the forecast, is it time to apply nitrogen to the wheat?
The short answer. Wait until green-up to apply N to wheat.
The long answer. Wheat does not require large amounts of N until stem elongation/jointing (Feekes Growth Stage 6), which is generally the middle or the end of April depending on the location in the state and spring temperature. Ohio research has shown no yield benefit from N applications made prior to this time. Soil organic matter and/or N applied at planting generally provide sufficient N for early growth until stem elongation.
Nitrogen applied prior to rapid uptake by the plant has the potential to be lost and unavailable for the crop. Nitrogen source will also affect the potential for loss. Urea-ammonium nitrate (28%) has the greatest potential for loss, ammonium sulfate the least, and urea would be somewhere between the two other sources. Continue reading

The profit margin outlook for corn, soybeans, and wheat is relatively positive as planting season approaches. Prices of all three of our main commodity crops have moved higher since last summer and forward prices for this fall are currently at levels high enough to project positive returns for 2021 crop production. Recent increases in fertilizer prices have negatively affected projected returns. Higher crop insurance costs, as well as moderately higher energy costs relative to last year, will also add to overall costs for 2021.
Production costs for Ohio field crops are forecast to be modestly higher compared to last year with higher fertilizer, fuel, and crop insurance expenses. Variable costs for corn in Ohio for 2021 are projected to range from $386 to $470 per acre depending on land productivity. Variable costs for 2021 Ohio soybeans are projected to range from $216 to $242 per acre. Wheat variable expenses for 2021 are projected to range from $166 to $198 per acre. Continue reading
“What are the right decisions for phosphorus management in crop production that reduce water quality impacts?” is a common question I have from farmers looking to improve yield yet are concerned about downstream water quality impacts of phosphorus.
A representative agronomic soil test has long been an essential tool for sound agronomic nutrient management decisions. That same agronomic test result can be a useful indicator for identifying fields where additional conservation practices might improve water quality. Fields with Soil Test Phosphorus (STP) levels two to three times higher than the agronomic need result in increased phosphorus losses measured on the edge of field water quality monitoring.
As soil test results are reviewed this fall, consider keeping a list of fields in three categories based on STP levels that define the risk of yield loss for the corn/soybean rotation and risk of increased water quality impacts.
- Less than 20 PPM Mehlich 3 STP (or 30 PPM if wheat/alfalfa in the rotation)
- Between 20-40 PPM (or 30-50 PPM if wheat/alfalfa are in the rotation)
- Greater than 50 PPM
The Tri-State Fertilizer Recommendations provide the foundation for agronomic nutrient management recommendations from the land-grant universities in Ohio, Michigan, and Indiana. The original publication, which came out in 1995, has been comprehensively updated with the release of the 2020 Tri-State Fertilizer Recommendations for Corn, Soybean, Wheat, and Alfalfa.
The publication relies on Ohio-generated data from 198 farmer-coordinated, on-farm trials in 39 Ohio counties and long-term plots at OARDC Ohio Agricultural Research and Development Center Agronomic Research Stations conducted from 2006-18. This data validates the recommendations against modern hybrids and varieties and agronomic management practices under current weather conditions. Key recommendations from the guide are included here.

The link for the Paulding County pesticide and fertilizer re-certification is active and live. The new option for 2019 to pay by debit or credit card. Registration is needed to be filled in online even if you are not paying by credit card. I realize some applicators have stopped in the office and paid. We will be sending the online link in an individual email for all those who pre-registered by calling our office. Thanks for your patience during our learning year. Continue reading
