  		Fig. 1. Effect of management intensity and evaluation date on herbage mass (A), existing litter mass (B), and rate of litter deposition (C) of grazed Pensacola bahiagrass pastures during 2002–2003. Means followed by the same letter, within an evaluation date, are not different (P > 0.10) by the SAS LSMEANS test. SE = 490 kg DM ha–1 for herbage mass, 356 kg OM ha–1 for existing litter mass, and 6.8 kg OM ha–1 d–1 for rate of litter deposition.

  		Fig. 2. Effect of management intensity and evaluation date on C to N ratio (A), neutral detergent fiber (NDF; B), and acid detergent fiber (ADF; C) of existing litter on grazed Pensacola bahiagrass pastures during 2002–2003. Means followed by the same letter, within each evaluation date, are not different (P > 0.10) by the SAS LSMEANS test. SE = 2.3 for C:N, 224 g kg–1 for NDF, and 119 g kg–1 for ADF.
