For steady-state conditions this equation is set equal to 0, because at a given depth x, concentration does not change with time. Steady-state models are generally more amenable to mathematical solution than are non-steady-state models. Unfortunately, diagenesis in many shoal-water carbonate sediments is significantly influenced or even dominated by non-steady-state processes. 

Sources and Diagenesis of Shoal-water Carbonate-rich Sediments... 

A major complicating factor in the diagenesis of shoal-water carbonate-rich sediments is that much of the organic matter oxidation can take place via bacterially mediated sulfate reduction. If marine plankton-like organic matter is oxidized via sulfate reduction, the nutrients phosphate and ammonia are also produced (Equation (6)) ... 

Carbonate minerals in modem marine sediments can readily be divided into those found in shoal-to-shallow and deep-water environments. The factors controlling the sources, mineralogy, and diagenesis of carbonates in these environments are very different. Within the shoal-to-shallow water environment, the sources and diagenesis of carbonates differ substantially between carbonate-rich and primarily siliciclastic sediments.
