Soil production function refers to the rate of bedrock weathering into soil as a function of soil thickness. A general model suggests that the rate of physical weathering of bedrock (de/dt) can be represented as an exponential decline with soil thickness: d e / d t = P 0 exp [ − k h ] {\displaystyle de/dt=P_{0}\exp {[-kh]}} where h is soil thickness [m], P0 [mm/year] is the potential (or maximum) weathering rate of bedrock and k [m−1] is an empirical constant.
