North Carolina Cotton: Planting Conditions as of April 23

The chart below illustrates how we define planting conditions. We cap DD60’s at a maximum value of 10 for each day. If you are computing DD60 accumulation on your own and a day is predicted to have 15 DD60’s, only use 10 for that day. We also lower the planting conditions by one category if a low of 50 or less or DD60=0 is predicted on day of planting.

Soil temperature at a 3 inch depth was 56.9 degrees at 7 this morning (April 22). That is below what we would like to see for planting cotton. The soil temperature at 7 on April 21st was 54.5, so hopefully we will see soil temps rising over the next few days.

The DD60s predicted for the 5 days following planting at Rocky Mount are included in the table below. Special thanks to Dr. Sandy Stewart for helping us with a program to help automate the calculations for this chart.

It is certainly possible to achieve a good stand in marginal conditions. Please consult Strategies for Planting Cotton in Suboptimal Conditions if you decide to plant under marginal conditions.
