  1. Analysis of variance of weekly animal grazing hours (hr ha−1 AU−1) based on forage species [big bluestem (native grass mix) and orchardgrass (non-native)] × soil moisture (aquic and udic) × fertility [fertilized with poultry litter and a control (0 kg N ha−1)]. A dataset with a total of 3951 observations representing animal visit frequency by each individual animals was used for this analysis.
  2. aSpp, forage species (native and non-native); moisture, soil moisture (wet/aquic and dry/udic); fert, fertility (fertilized with poultry litter and a control); week, week of grazing-season, DF degrees of freedom, SS sum of squares, MS mean square error.
