Our mostly sunny and mild October has helped keep 4 inch depth soil temperatures well above 50 degrees which is a key threshold used for fall nitrogen application in fields (temperatures need to be colder than 50 to make the application successful). Our recent stretch of cool weather has allowed temperatures to dip below 50 for the first time this fall and as is shown in the featured chart, this makes for the latest date in the fall season for the first sub 50 degree to have occured based on our data back to the mid 80s.
