Battle for the Belt: Season 2 Episode 3- April Weather Update

Episode 3 of Battle for the Belt is now available:

In episode 3, Dr. Aaron Wilson, State Climatologist of Ohio, gives us a spring weather update! Tune in and watch his weather and soil condition updates as we approach planting season. For more details, also check out Dr. Wilson’s article in this issue of the CORN newsletter titled "Spring 2024 Weather & Soil Conditions: Update 3.”

Planted Soybean

Figure 2. March 25th planted soybean on April 8th.

South Charleston received about 2 inches of rain last week (Table 1.), which caused flooding conditions in the soybean plots and soil saturation in the corn plots for planting date 1 (planted on March 25). Because of the warmer weather, growing degree days (GDDs) are accumulating quickly. However, it is important to keep in mind that growth is not only determined by air temperature but also by soil temperature until corn reaches the six-leaf stage. The average 2-inch soil temperature for the week was 56°F, which is satisfactory. Corn begins to emerge at about 100 air-growing degree days, and with warm temperatures that should be achieved this week!

If you would like to learn more about growing degree days and emergence expectations, take a look at this past CORN News Article,  “Growing Degree Days vs. Calendar Days – How Long Will Emergence Take?”.
