The so‐called priming effect occurred during the first 22 days when C 14 labeled soybean (Glycine max) stems or leaves were added to Cecil and Bladen soils under constant moisture and under wetting and drying cycles. After 96 days the effect of added plant tissue upon native soil organic matter decomposition was significant for Cecil but not for Bladen soil Wetting and drying greatly increased soil organic matter decomposition and increased the priming effect in the Bladen soil for the first incubation period but decreased this effect in the Cecil soil.
