Description: Total soil CO"2 efflux at the soil surface (F"S) is the dominant respiratory flux in forest ecosystems. Therefore, minor changes in F"S would impact net ecosystem productivity (NEP) and, thus, short- and long-term carbon sequestration. Intensive site management (i.e., site preparation, competition control, fertilization amendments) impacts F"S by influencing resource availability and site productivity. We evaluated the long-term (rotation-age) effects of site preparation and fertilization on F"S and heterotrophic respiration (R"H) in a 33-year-old loblolly pine (Pinus taeda L.) plantation located in the wet flats on the Lower Coastal Plain of Virginia. We utilized an existing long-term study that consisted of a randomized complete block design split by fertilizer treatments that were replicated three times. Each of the three site preparation treatments: (i) chopped, (ii) windrow-bedded and (iii) ditched were split by four fertilizer treatments: (1) no nutrient additions (control), (2) 84kgPha^-^1 (P), (3) 112kgNha^-^1 and 84kgPha^-^1 (NP) and (4) 112kgNha^-^1, 84kgPha^-^1, and 2240kglimeha^-^1 (NPL). Total soil CO"2 efflux and heterotrophic respiration were measured using an infrared gas analyzer with a dynamic closed cuvette chamber. We found decreased F"S (P  for more information click here respiration Respiratory Physiology: Mosby Physiology Monograph Series (Mosby's ...
