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). Combined with precipitation up to twice the normal amount in some areas, the weather is certainly not cooperating with ideas of an early jump on planting.

Author(s): Greg LaBarge, CCA
The Ohio Agricultural Research and Development Center (OARDC) Agricultural Research Station located throughout the state have 2 and 4 inch bare surface soil temperatures monitored on an hourly basis. The chart provided here summarizes the average daily two inch bare soil temperature from several stations. More complete weather records for the just passed day as well as long term historical observations can be found at


Seed is Precious

Seed is Precious

Author(s): Anne Dorrance
We are off to a rough start again, saw the pictures on Facebook of replanting. So I thought I should chime in here about how precious this seed is and what a seed treatment can and cannot do. 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.
