Evaluation of Phosphorus Transport in Surface Runoff from Packed Soil Boxes

Abstract: Evaluation of phosphorus (P) management strategies to protect water quality has largely relied on research using simulated rainfall to generate runoff from either field plots or shallow boxes packed with soil. Runoff from unmanured, grassed field plots (1 m wide x 2 m long, 3-8% slope) and bare soil boxes (0.2 m wide and 1 m long, 3% slope) was compared using rainfall simulation (75 mm h(-1)) standardized by 30-min runoff duration (rainfall averaged 55 mm for field plots and 41 mm for packed boxes). Packed box… Show more

“…Lysimeters were subjected to 1-hour rainfall simulations (61 mm [2.4 in] precipitation) on May 1 and June 12, 2008 (15 and 42 days after litter application), using a modified version of the National Phosphorus Research Project protocol (Kleinman et al 2004). In between simulated rainfall events, lysimeters were irrigated by hand semiweekly (11 events), with the total irrigation depth approximating the 30-year average precipitation for the research site during March and April.…”

“…Thus, one could argue that to compare data from NPRP plots to field-or watershed-scale data would be to make interpolations far beyond what the NPRP was intended to represent. There have been a few studies to examine the spatial scaling influences of box-and plot-scale simulation work using the NPRP protocols (Sharpley and Kleinman 2003;Kleinman et al 2004;Guidry et al 2006). Kleinman et al (2004) and Guidry et al (2006) ).…”

Kleinman et al (2004) and Guidry et al (2006) ). These studies compared P loss parameters for soils from the same fields/catchments, whereas small-scale studies are often used to develop or calibrate models based on data from one field or catchment, which is then applied to another catchment.…”

“…Previous reports indicated runoff concentrations and losses of dissolved P were directly related to concentrations in top-dressed amendments [11,12]. Incorporation of CDM or CMB at volume-based rates increased concentrations of extractable soil P and dissolved P in runoff [13][14][15]. Variation of nutrient concentration and form among composted materials, including CDM and CMB, and amended soils needs to be evaluated in relation to nonpoint-source losses [12,16].…”
