Dynamics of soil organic carbon and its fractions after abandonment of cultivated wetlands in northeast China

Agricultural abandonment in Mediterranean reclaimed peaty soils: long-term effects on soil chemical properties, arbuscular mycorrhizas and CO2 flux

“…These inconsistencies could be attributed to the sampling depth and to the time elapsed since land-use conversion (Liebig et al, 2004;Jinbo et al, 2007;Raiesi, 2012;Gaji c, 2013). In fact differences were observed only at a 0-15 cm depth and already six years after abandonment.…”

Pursuing robust agroecosystem functioning through effective soil organic carbon management

“…Stratification of SOC with depth is common in many natural ecosystems, managed grasslands and forests, and conservation-tilled cropland (Figure 3) [62][63][64][65][66][67][68]. The reason why surface SOC is vitally important in natural (and agricultural) systems is because the soil surface accepts nutrients and biochemicals (fertilizers and pesticides) from aboveground vegetation and litter into the soil profile or rejects them as runoff contamination; receives intense impact of rainfall that can either allow rapid infiltration with development of permanent biopores or create surface crusts with disruption of surface aggregates; partitions gas flow into and out of soil; and creates either an oasis of litter (surface residue)covered soil, providing organic substrates and protected microenvironmental conditions for support of biological diversity or a barren surface devoid of habitat protection.…”

Carbon dynamics of soil organic matter in bulk soil and aggregate fraction during secondary succession in a Mediterranean environment

“…Jinbo et al (2007) found that abandonment led to an increase in SOC in a favourable (medium rainfall and high temperatures that supported high primary productivity) climate but a decrease in SOC in an unfavourable climate. This finding, however, was not confirmed by other experimental evidence.…”
