The contentious nature of soil organic matter
@article{Lehmann2015TheCN, title={The contentious nature of soil organic matter}, author={J. Lehmann and M. Kleber}, journal={Nature}, year={2015}, volume={528}, pages={60-68} }
The exchange of nutrients, energy and carbon between soil organic matter, the soil environment, aquatic systems and the atmosphere is important for agricultural productivity, water quality and climate. Long-standing theory suggests that soil organic matter is composed of inherently stable and chemically unique compounds. Here we argue that the available evidence does not support the formation of large-molecular-size and persistent ‘humic substances’ in soils. Instead, soil organic matter is a… CONTINUE READING
