The recent cold temperatures experienced during 31 March – 14 April 2022 were enough to cause freeze damage to winter wheat in parts of Kansas. The actual freeze damage will be region-specific depending on crop growth stage and minimum temperatures (some regions had a worst combination of temperatures and crop growth stage) and, within a region, field specific owing to many individual aspects such as crop density, residue level, etc. While there is nothing that we can do immediately, growers can prioritize fields where they sample for freeze damage symptoms depending on conditions that were more likely to result in freeze damage.

A manual calibration at least once a year is needed to ensure the rate controller is functioning properly and that the rate controller is not forced to operate outside the pressure operating range for the nozzles on the sprayer boom.

Legumes still can provide valuable N to today’s cropping systems. Legumes also contribute a non-nitrogen rotation effect due to addition of soil organic matter and improvement in soil health. Corn grown following alfalfa stands that are 2+ years old (and contained at least 50% alfalfa) require no nitrogen fertilizer on many soils. Red clover N credits are less than for alfalfa.

The Census of Agriculture is designed to be a complete count of U.S. farms, ranches, and operators. The agency defines a farm as anywhere $1,000 or more of fruit, vegetables or food animals are raised or sold.
