Determination of dry matter practical report
WebDry-matter definition: Dry weight; a measurement of the mass of something when completely dried. . WebThe organic matter of soils is generally determined by converting it to carbon dioxide by means of moist and dry combustion. The carbon dioxide thus evolved is then calculated to organic matter by the use of a conventional factor, 0.471. It has been found, however, that the percentage of carbon in the organic matter of soils varies widely.
