Spring Warm-Up: How does 2018 Soil Temperature Compare?

Author(s): Aaron Wilson, Elizabeth Hawkins
The calendar says it’s time for spring field activity in Ohio and farmers are eager to prep fields and plant this year’s crops. However, average temperatures across Ohio have remained cooler than usual with the previous 30-day period (March 16 - April 15, 2018) running 2 to 6 degrees Fahrenheit below normal (based on 1981-2010).

In this eastern soybean belt – we have a lot of poorly drained soil. More importantly, we also have a lot of inoculum and a great diversity of watermolds, Pythium and Phytophthora, that can infect both corn and soybeans. When soils are saturated – like today and tomorrow, these watermolds will form swimming spores that are attracted to the young seeds and seedlings. Based on the past 10 years of r

When to begin Alfalfa Weevil Scouting

Author(s): Andy Michel, Kelley Tilmon
The larvae of alfalfa weevil can cause considerable damage, especially when alfalfa is just starting its growth in the spring. When temperatures are greater than 48oF, the adults become active and start to lay eggs. After hatch, the plump and green larvae (which resemble little worms) feed, with 3rd instar (mid-aged) larvae being the hungriest. The heaviest feeding can occur between 325 and 500 heat units. Right now, the heat units (base 48oF) for the Western Ag Research Station in South Charleston are 98, and for the South Station in Piketon is 175.
