equation: denitrification

brief description:

Two methods to estimate denitrification are proposed. The first uses a kinetic equation, while the second uses a constant denitrification fraction. In both methods, denitrification depends on nitrogen deposition, and thus changes as deposition changes. The kinetic equation is based on a Michaelis-Menten reaction mechanism. When including the pH dependence of the denitrification rate, more elaborate and iterative models have to be used. Different acidity deposition levels will lead to different soil pH, causing the critical load to change with soil acidity. Therefore it is suggested to use pH = 5, leading to $h(pH) = 1$.
