They dig as little is possible, and only when the soil is moist rather than wet, because cultivation increases the oxidation of soil organic matter and produces carbon dioxide.

Studies have backed this up Schonbeck showed that a reduction of Mg saturation had no detectable effect on soil organic matter, biological activity, weed growth, or incidence of disease.
43.
Tropical peatlands, which coexist with swamp forests within the tropical and subtropical moist broadleaf forests biome, store and accumulate vast amounts of carbon as soil organic matter-much more than natural forests contain.
44.
Collectively many of Dr . Laird's contributions to soil science have provided insight into understanding soil organic matter and clay interactions and, thus, the genesis of soil peds from the molecular viewpoint.
45.
DSSAT is built with a modular approach, with different options available to represent such processes as evapotranspiration and soil organic matter accumulation, which facilitates testing different representations of processes important in crop growth.
46.
Strong slopes with equatorward aspects tend to have soil organic matter levels and seasonal influences similar to level slopes at lower elevation whereas poleward aspects have soil biological processes that are temperature dependent.
47.
In the original version of IBIS [ Foley et al . 1996 ] there was no explicit belowground biogeochemistry model to complete flow of carbon between the vegetation, detritus, and soil organic matter pools.
48.
The small living beings that work on that decomposition chain are themselves part of the soil organic matter, and form a food web of organisms that prey upon each other and are preyed upon.
49.
For example, studies have shown that tilling has had negative consequences towards soil organic matter ( SOM ), the organic component of soil composed of plant and animal decomposition and substances synthesized by soil organisms.
50.
There are a few plausible explanations for this trend, but the most likely explanation is that increasing temperatures have increased rates of decomposition of soil organic matter, which has increased the flow of CO 2.
