Publisher's Synopsis
Excerpt from Quantitative Relationships of Carbon, Phosphorus, and Nitrogen in Soils
Carbon may exist in soils as inorganic and as organic carbon. The agricultural value of organic carbon, or organic matter, of soils has long been recognized by the practical husbandman, and the scientific man early recognized its value when the applications of science were made to agricultural problems.
Mulder (i), in 1844, made an elaborate study of the organic matter of the soil, and seems to have been the first one to suggest that it consisted Of other elements than carbon, hydrogen and oxygen. He separated the organic matter into various supposedly pure organic compounds of an acid nature, which were analyzed and studied by the usual organic method.
