Dear Colleagues, I am pleased to invite you to publish your new humus data in a Special Issue "Research Progress on Extraction and Characterization of Humus" - Separations (MDPI).
Humus is a stable natural product of the joint evolution of living and nonliving matter. It is formed as a result of repeated transformation of plant and animal remains in the presence of minerals under the influence of biological, climatic, and geological factors for a long time. Humus is not just a specific product of biological waste disposal, but also an important soil component. In particular, it acts as a stabilizer of the physical and chemical state of soils. Moreover, it acts as a source and regulator of the supply of nutrients to plants and soil organisms while also serving as their habitat.
