Runoff and Nutrient Losses from Constructed Soils Amended with Compost
Figure 3
The mean sums of total P (TP) loss in runoff water over 10 rain events compared to mean total P concentration in 0 to 50 mm depth of contrasting roadside treatments on an 8.5% slope. Soil was sampled from established perennial grass, compost-manufactured topsoil, and erosion-control compost treatments after the final rain event.
