Fig. 3. Annual K uptake in Coastal bermudagrass receiving no fertilizer or combinations of fertilizer N and broiler litter to equal 269 kg ha^–1 N in all treatments in 1999, 2000, and 2001. Values within a year with a different letter are significantly different using Fisher's protected LSD test at the 0.05 level. Values for LSD (P = 0.05) at Newton were 38, 53, and 64 in 1999, 2000, and 2001, respectively. Values for LSD (P = 0.05) at Mize were 67, 37, and 64 in 1999, 2000, and 2001, respectively.
