Ammonia-nitrogen #ux (NH
) was determined from six anaerobic swine waste storage and treat-
ment lagoons (primary, secondary, and tertiary) using the dynamic chamber system. Measurements occurred during the
fall of 1998 through the early spring of 1999, and each lagoon was examined for approximately one week. Analysis of #ux
variation was made with respect to lagoon surface water temperature (&15 cm below the surface), lagoon water pH, total
