Studies on the Carbon and Nitrogen Cycles in the Soil. III. The Formation of Natural Humic Matter
Published online by Cambridge University Press: 27 March 2009
Extract
Experiments are described in which the decomposition of various plant materials and of purified preparations of plant constituents, during rotting under neutral aerobic conditions in the presence of soil organisms, has been studied in relation to the formation of humic matter.
The formation of humic matter was more closely related to the change in the lignin content than to the change in content of the other groups of plant constituents estimated.
