放牧草地牲畜排泄物的沉积是不均匀的，集中在阴凉处，水，和补充饲料的位置。重复粪便或尿液沉积到草地斑块的后果还没有很好地量化的影响，牧草干物质收获（DMH），饲料营养价值，养分回收。这些反应在“彭萨科拉”bahiagrass（Paspalum notatum Flugge）草地上进行了测量，该草地用来自两个排泄物源牧场的两种排泄物类型（粪便和尿液）（基于氮肥和放牧率的平均和高管理强度）以四种频率（0，1，
Livestock excreta deposition in grazed grassland is nonuniform and concentrated around shade, water, and supplement feeding locations. The consequences of repeated dung or urine deposition to grassland patches have not been well quantified in terms of effects on forage dry matter harvested (DMH), forage nutritive value, and nutrient recovery. These responses were measured on ‘pensacola’ bahiagrass (Paspalum notatum Flugge) swards treated with two excreta types (dung and urine) from two excreta source pastures (the Average and High management intensities based on N fertilizer and stocking rates) applied at four frequencies (0, 1,
