Organic Matter Characterization

Schnitzer, M.·1982·Agronomy Monographs

Abstract

H. L. Bohn emphasized the importance of soil organic matter C in the C cycle as a major source of CO2 and as a C reservoir sensitive to changes in climate and atmospheric CO2 concentrations. It has been estimated that 65 to 75% of the organic matter in predominantly inorganic soils consists of humic materials, that is, humic acid, fulvic acid, and humin. The remainder is composed mainly of polysaccharides and protein like substances. Thus, humic substances are the major components of soil organic matter, and the discussion of this chapter is confined to these materials. Important characteristics of all humic materials are their ability to form water-soluble and water-insoluble complexes with metal ions and hydrous oxides and to interact with minerals and a wide variety of organic compounds. The main spectrometric methods used by soil organic matter specialists include absorption in the UV, visible, and especially infrared region.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
