Implementation of Exponential Depth Distribution of Organic Carbon in the CENTURY Model
نویسنده
چکیده
An important component in calculating budgets of terrestrial soil carbon is an estimate of total soil organic carbon. The CENTURY model simulates organic C in the top 20 cm of soil only, so a method for projecting the depth distribution of organic C is necessary for estimates of the profile total. This document describes the implementation of the exponential depth distribution of organic C in CENTURY soil organic matter model. This model replaces the original CENTURY version 5 algorithm for distributing C below the simulation layer. Implementation of this algorithm also required changes to the algorithms for the layered soil, erosion, and deposition.

In this paper, the Radiation Transfer Equation(RTE) for a non-gray gas between two large parallel planes has been solved and the temperature distribution obtained. With the RTE, solution heat fluxes are also determined. Since and are two components of most combustion products, the problem has been solved for these two gases. The results were, whenever possible, compared with data reported el...

Background and objectives: Organic carbon is one of the important parameters to determine soil fertility, and production ability and is a mind index for showing soil quality, especially in dry and semi-dry lands. The rangelands are composed of about 50 % of the world's lands and have more than 33 % of carbon reservoirs on earth. Considering the ranges as the most important terrestrial ecosystem...
