Under stabilized environmental conditions, whether in virgin soil or cultivated soil, there is eventually established a fairly constant level of organic matter. This state of equilibrium is reached when carbon loss, chiefly as carbon dioxide, balances the gain through the additions of vegetable matter...
ACCUMULATION OF ORGANIC MATTER IN A CHRONOSEQUENCE OF SOILS DEVELOPED ON WIND-BLOWN SAND IN NEW ZEALAND SummaryA study was made of the amounts and distribution of C, N, S, and organic P accumulated over a period of 10 000 years of soil development on wind-blo... JK Syers,JA Adams,TW...
The role of organic matter in soil fertility has been well known for hundreds of years, but the role of humus quality and its environmental functions has been discovered only during the last 30 years. We outlined in an earlier study our equivalent humus parameter for the characterization of hum...

Managing the selenium content in soils in semiarid environments through the recycling of organic matter. Appl. Environ. Soil Sci., 2013: 283468Moreno RG, Burdock R, Alvarez MCD, Crawford JW (2013) Managing the selenium content in soils in semiarid environments through the recycling of organic ...
Soils store two or three times more carbon than exists in the atmosphere as CO2, and it is thought that the temperature sensitivity of decomposing organic matter in soil partly determines how much carbon will be transferred to the atmosphere as a result
plant population decreased as soil OM content decreased in 3 of 4 yr. On an annual basis, highest total aerial dry matter and grain yields were associated with highest OM contents. The contribution of 1 Mg OM ha–1 to soil productivity, across the range of 64 to 142 Mg OM ha&#...
Organic matter content controls soil thermal diffusivity We find a significant negative correlation between soil thermal diffusivity (log-transformed) and soil organic carbon density (Fig.1). This empirical result confirms that soils with more organic materials have a lower thermal diffusivity. Among all...
