Concepts and Misconceptions of Humic Substances as the Stable Part of Soil Organic Matter: A Review
TL;DR: The concept of humic substances has been questioned in two main directions as discussed by the authors in the last three decades, and the concept of soil humic substance has been investigated in the literature.
