Pests & Disease Outlook

Image
  The 2025 winter weather has been colder than most years. Temperatures in the teens and single digits have caused the soil to freeze deep. While this may reduce some insects and pests, it can also harm wheat and hay crops. How deep the soil freezes depends on the amount of snowfall received. Snow acts as a natural insulator, blanketing the soil and preventing deeper freezing. This year, the northern part of Ohio received less snow than some areas to the south. Reports from Toledo indicate significantly less snowfall than counties further south. Snow prevents wind from desiccating crops like wheat, barley, hay (alfalfa, red clover, etc.), and cover crops. Several northern farmers are already reporting wheat and barley damage. Cover crops may also suffer, and as thawing begins, expect damage to the crowns of hay crops, especially alfalfa roots, which tend to heave—just like fence posts. Slugs and voles tend to decrease in cold winters, with cycles occurring every 2-5 years. During d...

Increasing Nitrogen & Phosphorus Efficiency

Image
Plants need both Nitrogen (N) and Phosphorus (P) to grow well. A lack of these two elements limits growth. Farmers apply N & P fertilizer, especially to corn, to increase yields, but there is a limit. Since the 1900s, N fertilizer applications have increased 5X or 500%, while P fertilizer inputs have increased 76%. Too much N fertilizer ties up soil P levels and other nutrients. A recent study looked at how farmers may be able to reduce N fertilizer inputs while increasing crop yields and enhancing P fertilizer use efficiency. P fertilizer stocks are running low in the USA (expected to be depleted by 2050), so farmers need to start thinking about how they can use existing stocks of P fertilizer better, both mined and in the soil, to enhance yields. A large meta-study (combined results from 222 independent studies) looked at how N responds to P fertilizer. Overall, adding P fertilizer had a positive effect on plant N uptake, resulting in higher plant growth above and below ground. I...
