Witryna1 maj 1992 · We describe a simple method for dispersion of soil to isolate a particulate organic-matter (POM) fraction that may represent an important SOM pool in grassland soils. The POM fraction was isolated by dispersing the soil in 5 g L −1 hexametaphosphate and passing the dispersed soil samples through a 53-µm sieve. WitrynaThis process is similar to what we think happened on the early Earth, whose first atmosphere was mostly Nitrogen and Methane. The Earth, however, has a surface upon which the complex organic products collected instead of being converted back into Methane, allowing these organics to collect and form the pool of ingredients that … ifcc repairWitrynaNitrogen can also become available for plant use from organic N sources.
