Two long term fertility experiments on a Dothan fine sandy loam (Plinthic Paleudult) included peanuts for short periods. Peanuts were in a rate of N-P-K experiment during 1973-75 and 1981-83. They did not respond to N. Mehlich-1 extractable soil test P dropped from 30 mgkg in 1954 to 11 mgkg by 1983. No yield response to P was found for any crop. The soil test K level of 44 mgkg remained about the same over the 30 years. Cotton yield was doubled by the addition of 37 kgha of K, which also increased the soil test level to 56 mgkg. Peanut and corn yields were increased by 19 kgha K, with no further response to higher rates. The addition of lime produced large yield increases from all three crops.
