  1. Drought Continues but Some Relief is in the Forecast

    Author(s): Aaron Wilson

    Meteorological winter has come to a close as we transition now to spring in the Ohio Valley. Looking back at winter 2025-26, it was cold, with our winter average temperatures ending 2-5°F below normal (1991-2020) for December – February. It was also quite snowy across much of western, southern and eastern Ohio. However, this did not tranlate into overall wetter conditions, as precipitation ran well below normal (Figure 1).

  2. Top-dressing Wheat with Liquid Manure

    Author(s): Glen Arnold, CCA

    Wheat fields will be firming up across Ohio and spring top-dressing with nitrogen fertilizer will soon start in the most southern counties. Livestock producers and commercial manure applicators may be considering applying liquid manure as a top-dress fertilizer for wheat once we get through the rain expected this week.

    The C-FARM (https://carbon.osu.edu/c-farm) research team is farmers, landowners, or other decision-makers managing cropland or farmland to participate in a comprehensive survey focused on carbon markets. Your responses will help researchers understand the challenges, questions, and information gaps that influence participation in agricultural carbon programs, ultimately guiding future outreach and extension efforts.
