The dry weight of organic matter
網頁The weight remaining is the dry matter (dm) of the sample. In this method, the temperature is sufficiently low enough for the sugars not to burn. When the sample contains a small amount of sugar (<4-5%), the 'normal' drying method can be used: a fixed amount of sample is dried in a drying oven at 103 ° C to a constant weight (> 4 hours). 網頁expressed as a percentage of compost dry weight. Organic carbon (C) represents about half of the organic matter weight. Thus, if you know the organic C content, you can …
