What should be the soil temperature at planting time?
Ideally, the seedbed should be at least 68º F at the two inch depth, with dry weather and at least 50 DD-60s expected in the next 5 days.
Planting into cold soils increases the likelihood of chilling injury to seedlings, weak and variable stands and replanting. Replanting is expensive, can complicate herbicide and insecticide programs and delay maturity.
Generally this will be the last week of April or the first week of May. Some years differ and common sense must apply.

Cotton and corn acreage in Mississippi are more than 30% below March projections, while growers of soybeans and peanuts planted much more than initially forecasted.
STARKVILLE, Miss. -- Row crop growers in Mississippi used a relatively dry May to make up for planting time lost earlier in the spring due to wet weather and soggy fields.
As of May 24, planting progress for the state’s four major row crops was slightly behind their five-year averages but ahead of where it was at that time in 2019.
The Mississippi State University Extension Service has a new cotton specialist.
Brian Pieralisi was appointed to that role on April 1. He replaced Darrin Dodds, who took the helm of the university’s Department of Plant and Soil Sciences.
STARKVILLE, Miss. -- Weather always plays a role in the spring planting decisions of Mississippi row-crop producers, but the market impact of the ongoing COVID-19 pandemic is another variable they will have to consider in 2020.
STONEVILLE, Miss. -- Pathologists with Mississippi State University will be monitoring a relatively new plant disease in state cotton fields once the growing season is in full swing.
Cotton leafroll dwarf virus, or CLRDV, was first reported in Alabama in 2017. It is closely related to a cotton virus known to occur in South America. Historically, that virus has caused up to 80 percent yield losses in Brazilian cotton fields.
