Sorry, no etymologies found.
Composting is a way of achieving the natural microbial humification process that converts the material into another form — the main conversion taking place being that of carbon and nitrogen compounds.
Living in this very top layer of fluffy, crumbly, moist soil mixed with leaf material and humus, are the animals that begin the process of humification.
Organic Gardener's Composting Steve Solomon
As a general statement we may say that the ripest and heaviest peat contains 10 or 12 _per cent. _ more carbon and 10 or 12 _per cent. _ less oxygen than the vegetable matter from which it is produced; while between the unaltered vegetation and the last stage of humification, the peat runs through an indefinite number of intermediate stages.
The authors analyzed plant macrofossils, peat humification and testate amoebae to reconstruct a proxy climate record spanning the last 7500 years of an ombrotrophic bog, Temple Hill Moss, in southeast Scotland.
Working with plant macrofossil, peat humification, and testate amoebae data, which they obtained from cores extracted from an ombrotrophic bog (Temple Hill Moss in southeast Scotland), the authors reconstructed a proxy climate record spanning the last 7500 years.
Langdon et al. report that the plant macrofossil detrended correspondence analysis (DCA) and colorimetric humification data produced a millennial-scale periodicity of 1100 years, noting that "the only other peat-based palaeoclimatic reconstruction of similar length, Walton Moss (Hughes et al., 2000), also displayed an 1100-year cycle derived from the plant macrofossil DCA reconstruction."
