Abstract:

Change in grazing density can influence dung distribution patterns, with potential impacts on the abundance and frequency of dung beetle populations and nutrient dynamics in grazing systems. The goal of this research was to quantify and characterize the fate of nutrient pulses from beef-steer dung after deposition, and the associated effects of dung beetle activity. Mass and nutrient loss of dung, changes in soil nutrients below and around dung pats, and fluxes of greenhouse gases (GHGs) were monitored overtime.
