Determination of organic matter in soil
WebSome phosphorus is present as part of soil organic matter and becomes available to plants as the organic matter decomposes. Most inorganic soil phosphorus is bound tightly to the surface of soil minerals (e.g., iron and aluminum oxides). Warm, moist, well-aerated soils at a pH level of about 6.5 optimize the release of both of these forms. ... WebNov 20, 2024 · This paper reports on a new method for rapid determination of organic matter (OM) in soil and municipal sludge samples, based on a redox reaction (i.e., conversion of OM into CO 2 by dichromate), involving the headspace gas chromatographic technique (HS-GC).For the soil samples (with a lower OM content), the sample reaction …
