Runoff and Nutrient Losses from Constructed Soils Amended with Compost

Figure 2

Relationship between the mean sum of total P (TP) loss in runoff water over 10 rain events and mean soil-test P within 0 to 5 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 after the final rain event.
