Physical Fractionation of Soil and Organic Matter in Primary Particle Size and Density Separates, complexity of SOM and its importance to soil fertility have challenged generations of soil scientists, and numerous studies, of which some date back more than two centuries (see historical review in Kononova, 1961), have covered a vast array of aspects of SOM.作者: membrane 時(shí)間: 2025-3-25 01:38

The soil microbiota and fine roots may also be considered part of the SOM pool. The turnover of the different SOM components varies continuously due to the complex interaction of biological, chemical, and physical processes in soil.
