How to determine the Parameters of Soil? (9 methods)
Different parameters of soil can be determined by following methods: 1. Soil atmospheres: The soil gases are collected by an apparatus devised by Haley and Brierley (1953) and are tested in the laboratory for oxygen and carbon dioxide by Haldane- Gutherie gas analysis apparatus. image source: yesitsyomoma.files.wordpress.com 2. Soil organic matter: A reasonable estimate of soil organic matter can be obtained by loss of weight on ignition. About 5g of oven dried soil is taken, weighed carefully, and then heated red hot in a crucible for about half an hour. ADVERTISEMENTS: It is cooled in a desiccator, is reweighed and heated again. This procedure is continued until weight of soil becomes constant. The loss in weight, expressed as a percentage, represents the amount of oxidizable organic matter present. 3. Soil…
