Abstract
Organic layers of acid forest soils are highly dynamic carbon reservoirs. During forest succession the stored amount of organic carbon (OC) changes drastically. Because of feedback between OC storage in organic layers and in mineral soils and other compartments of the environment (plant, atmosphere, and groundwater), there is a strong need for applicable carbon balance models, particularly for organic layers. In this paper a simplified model for the carbon balance of organic layers (CABOLA model) of acid forest soils is presented. The model considers two horizons, the L and O horizon. Decomposition and transport processes are described by first order differential equations. C input into the organic layer is due to litter fall onto the L horizon. The governing equations are solved by integration. To demonstrate the model's capability of simulating the OC dynamics of organic layers, data on OC storage in organic layers of acid sandy forest soils with deep groundwater tables (Podzols) under pine stands were used. Together with literature data and some assumptions, these data were used for a first, rough estimation of the model parameters. Model calculations confirm that the CABOLA model is in principle able to simulate the dynamics of OC storage in organic layers during forest succession. Nevertheless, intensive research efforts will be necessary to independently parameterize the model for broad applications.
