Below are some recommendations from Scott Monfort (UGA Peanut Agronomist):
Soil temps around the state are in the high 60’s to high 70’s. The soil should be buffered from a few hours of cold temperatures during the night time as long as we are warming back in the high 70’s to mid-80’s during the day. The low 70’s daytime and 50’s night time temperatures for more than 1 to 2 days will drive the soil temps down. With this in mind, I would consider not planting until this cold front has passed.
However, I know some growers need to continue planting so please consider the following:
- If you are dryland and you are afraid of losing needed moisture then I would go ahead and plant.
- If you are irrigated, you could hold off until cold front moves out.
- If you have questionable seed quality, I would wait to plant until it warms up.
- Soil temperatures can be different across the state. (check your county weather stations)
- The eastern part of the state will be at more risk than the Southwest part of state.
- Freshly turned soil will be colder than normal – let field sit for a day or so to warm up
- For strip tillage fields with cover, soils are typically colder than conventional tillage fields so you may want to allow extra time for soils to warm up.
- What if I have a lot of acres and need to keep planting or I just want to keep planting?
- Make sure you are planting with good quality seed
- Add appropriate in furrow fungicide to help with seedling disease
- Do not plant more than 2.5 inches deep
- Try not to add irrigation during the coldest days where night time temperatures are in the 40’s and 50’s and the day time temperatures are below 70-75. If you need to go ahead and add irrigation do not apply more than is needed to activate herbicides.
