Abstract: Agricultural losses of dissolved reactive phosphorus (DRP) emanate from both "old P" from historic P applications, "old P", and recently applied fertilizer, "new P", and understanding the relative contributions of these sources is important for… read more here.

Abstract: A recently developed model, SWATDRAIN, was used to assess the alterations in water balance components, discharge, and sediment loads due to tile drainage practices in a heavily tile drained watershed in Ontario, Canada. Furthermore, the… read more here.

Abstract: Controlled tile drainage (CTD) is an agricultural management practice with well-documented water quality and agronomic benefits. However, due to field water drainage abatement effects, the practice could potentially impact soil respiration. The δ13C of soil… read more here.
