Sensitivity analysis of six soil organic matter models applied to the decomposition of animal manures and crop residues

Italian Journal of Agronomy, 2016
Two features distinguishing soil organic matter simulation models are the type of kinetics used to calculate pool decomposition rates, and the algorithm used to handle the effects of nitrogen (N) shortage on carbon (C) decomposition.

THE KINETICS OF THE DECOMPOSITION OF PEROXIDE BY CATALASE [PDF]

Journal of General Physiology, 1925
It has been shown that the experimental results obtained by Morgulis in a study of the decomposition of hydrogen peroxide by liver catalase at 20°C. and in the presence of an excess of a relatively high concentration of peroxide are quantitatively accounted for by the following mechanisms. 1.
