Identification of the sample and material being tested, such as boring number, sample number, test number, container number etc. It is usually expressed as a percentage or weight basis in seed-testing laboratory. For example, if the ambient air is at 70°F and 50% relative humidity, the relative humidity in the oven will be about 1% with an equilibrium moisture content of about 0.1 to 0.2%. A knowledge of the moisture content is used as a guide to the classification. In this method of Moisture Content Determination of soil, a known weight (W) of the representative wet soil sample is dried over night in an oven operating at temperatures between 105°C and 110°C ; and the weight of dry soil sample (W solid) is obtained. It is also used as a subsidiary to almost all other field and laboratory tests of soil. Also, moisture content is a measure of the shrink-swell and strength characteristics of cohesive soils. It is, therefore, imperative that the moisture content determination should be made accurately in accordance with the Rules of Seed Testing. Cancel.

Soils typically contain a finite amount of water, which can be expressed as the soil moisture content. AS 1289 B1.1-1977. The purpose of irri.gation is to replenish the water stored in soil that has been extracted by living plants and used by them for their growth. Hence for moisture content determination the soil samples are dried to the temperature at which only pore water is evaporated. 3. Much larger soil samples may require occasional stirring so that a uniform drying takes place; Remove from the oven with tongs or heat-treated loves and weigh immediately; some manuals claim that convection currents affect the result, but this writer has never found this to be true; The total weight difference between W3 and W2 is the weight of the water that was evaporated from the soil.

In outdoor environments, water is added to soil naturally through rainfall or deliberately with the irrigation of plants. Miscellaneous: knives, spatulas, scoops, quartering cloth, sample splitters, etc. Moisture presents in the cell walls and cell cavities, may be removed up to fiber saturation point, without any effect of other than reduction in bulk density but any other reduction in moisture content results in the shrinkage of timber. Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Weigh each of the empty moisture cans with their lids and record their weight W1 and its number; you may have to mark it with a felt tip pen. Often, moisture content alone may not be enough to predict shelf life. doi: 10.17226/22920.
