Results from a meta-analysis on the long-term effects of metal contamination (Cd, Cu, Pb, and Zn) on soil C and N cycling showed decreasing organic C (OC) and total N (TN) contents in metal-contaminated soils, due to the lower plant biomass production and consequently to the reduced input of fresh organic remains into the soil, and/or increasing C:N ratios indicative of hindered mineralization [99].

Decomposition of carbon-14 labelled plant material under tropical conditions. It also shows how carbon compensation can attract land into forests from less carbon-sequestering land uses such as crop agriculture, thereby increasing carbon storage on the extensive margin.

The external hyphae have frequently been seen to proliferate preferentially in organic matter in soil (St John et al., 1983a,b; Warner, 1984), which would be an appropriate situation for the operation of this competitive effect.

Recent studies (Masson et al., 2008; Allen et al., 2010; Sailor, 2011) provide insight into the magnitude and variability of the anthropogenic heat flux (QF), which results from the emission of waste heat from stationary and mobile sources, and demonstrates the importance of this additional heating term in the surface energy balance and climate of urban areas. It places these advancements within the context of the soil ecosystem to demonstrate their contribution to fundamental soil processes across a wide range of scales, but also in the more applied areas of biodegradation and antibiotic production. 1982.
