Current situation in Stress Degree Days. We’ll see what this looks like in a week. 😳
Heading into this week's Midwest heat wave, I wanted to post the current accumulated stress degree day map.
Calculated by adding degrees above 86°F for each day.
Example: if today is 95°F, 9 SDDs are accumulated
>140 SDDs could result in corn yield loss
Data: PRISM April 1
