Addition of N to the soil accelerates the decomposition and release of nutrients from material with high C N ratio (Sinsabaugh et al. 2002).
At individual water contents, the presence of CO2 in the soil accelerates the steel MIC induced by SRB, which is associated with the increasing amount of SRB cells in CO2-containing soil.
While this fertilizer can counteract greenhouse gas loss by causing plants to grow (which then soak up carbon dioxide from the atmosphere), it can also feed microbes in the soil, accelerating the amount of carbon dioxide and methane - both greenhouse gases - that are being released.
Due to the nature of Madagascar's geology and soil, tavy also depletes the fertility of the soil, accelerating the crop rotation rate and necessitating expansion into primary forests.
"Permafrost thawing in organic Arctic soils accelerated by ground heat production represent a potentially critical global-scale feedback on climate change".
Furthermore, the nitrogen cycle on land could affect the carbon storage response to climate change, as represented by parameter γ in Equation 3. Since global warming could lead to enhanced activities of soil microbes, accelerated soil decomposition may reduce the total amount of soil carbon.
Addition of organic residue enhanced the soil organic carbon in soil and accelerated the microbial activities in soil (Dotaniya et al. 2013d).
In general, the embedded-rock fragment in the soil can accelerate soil erosion by changing the ratio of infiltration/runoff, surface roughness, and related hydraulic parameters, especially under higher slope gradients.
However, accompanied by the release of inorganic nitrogen that becomes soil nutrients, this accelerated soil decomposition rate might activate plant productivity.
From an environmental perspective, the transition from swidden to other land uses often contributes to permanent deforestation, loss of biodiversity, increased weed pressure, declines in soil fertility, and accelerated soil erosion.
