TL;DR: In this paper, a review of soil organic matter is considered to encompass a set of attributes rather than being a single entity and discussed here are total soil organic carbon and nitrogen, light fraction and macroorganic (particulate) matter, mineralizable carbon, microbial biomass, soil carbohydrates and enzymes.

TL;DR: In this paper, total organic C and natural C abundance were measured in a forest soil and a soil under corn (Zea mays L.) to assess management-induced changes in the quantity and initial source of organic matter.

TL;DR: In this paper, 13 C nuclear magnetic resonance (13 C NMR) and pyrolysis-field ionization mass spectrometry (Py-FIMS) were used to characterize plant tissue, isolated fractions, and whole surface soils and subsoils from a forest system and a maize (Zea mays L.) system.

TL;DR: In this paper, the authors examined carbon sequestration in agricultural soils in Canada as a possible strategy in slowing or stopping the current increase in atmospheric CO2 concentrations and provided estimates on the amount of carbon that could be sequestered in soils in various regions in Canada by reducing summerfallow area, increased use of forage crops, improved erosion control, shifts from conventional to minimal and no-till, and more intensive use of fertilizers.

TL;DR: In this paper, the authors conducted field experiments on four soils in Ontario and Quebec to test the hypothesis that short-term changes in soil organic C and the proportion of corn-residue C retained in soils are affected by soil texture, fertility, and tillage management.
