WebbThe high volume of undecomposed organic matter in mor humus leads to a high carbon-to-nitrogen ratio and can immobilize important plant nutrients like nitrogen. High carbon to … Webb6 jan. 2024 · Organic matter in the soil is suitable for promoting aeration, drainage, and soil moisture retention in the ground. The organic matter reduces erosion and supplies plant nutrients such as sulfur, phosphorous, and nitrogen to the plant’s root zone. Inorganic Soil
WebbThe high volume of undecomposed organic matter in mor humus leads to a high carbon-to-nitrogen ratio and can immobilize important plant nutrients like nitrogen. High carbon to nitrogen ratios slows the release of nutrients available to plants. The slow release of nitrogen in mor humus is often restrictive to plant development. See also.

We are testing the 'hydrocarbon oil index' after extraction in n-heptane via GC (from C10 to C40). The thing is there can't really be this much oil originated ...
Humification can occur naturally in soil or artificially in the production of compost. Organic matter is humified by a combination of saprotrophic fungi, bacteria, microbes and animals such as earthworms, nematodes, protozoa, and arthropods.
