Surface-Applied Biosolids Enhance Soil Organic Carbon and Nitrogen Stocks but Have Contrasting Effects on Soil Physical Quality

Figure 3

Effect of biosolids application rate and duration on relationships between (a) soil water-stable aggregates (% mass remaining) and soil bulk density (Mg m−3), (b) soil available water capacity (m3 m−3) and soil bulk density, (c) soil water-stable aggregates and soil organic carbon (%C), and (d) soil available water capacity and soil organic carbon. Closed symbols show 0–5 cm soils; open symbols show 5–10 cm soils. Means (se) are shown, and symbols occasionally obscure se bars.
