| Abstract/Contents: | "Black layer has been associated with a severe decline in the quality of turf on putting greens. It was suggested that the black layer results from dissimilatory sulfate (SO42-) reduction. This study was done to determine if SO42- reduction occurs in an existing black layer. Radioactive 35SO42- was used to calculate the rate of SO42- reduction in intact soil cores taken from an existing black layer in a 'Penncross' creeping bentgrass (Agrostis palustris Huds. 'Penncross') putting green. When 10-3 M 35SO42- with a specific activity of 1.554 ^D#^DOE 105 Bq·mg1- SO42- was injected into a core it reduced to sulfide (35S2-) at a mean rate of 7.1 nmol sulfur (S)/cm3 soil/d. Injecting azide (N3-) or molybdate (MoO42-) at 10% w/v with the label reduced the rate of SO42- reduction to 0.03 and 0.01 nmol S/cm3 soil/d, respectively. The effect of N3- confirmed that reduction of SO42- was biological, while the effect of MoO42- Confirmed that the entities responsible for the reductive cycling were sulfate-reducing bacteria (SRBs). This was the first proof that biological reduction of SO42- produces S2- in a black layer from a creeping bentgrass putting green. It was concluded that the respiration of indigenous SRBs was linked to development of this black layer. Thus, a key to successfully controlling black layer in putting greens must involve regulating the respiratory activities of SRBs." |
