Soil Carbon and Nitrogen Dynamics. Two thirds of the carbon in the terrestrial biosphere is stored in soil, primarily as decayed organic material. Carbon cycles rapidly between the atmosphere and soil as CO 2, and soils, depending on how they are managed, represent an important source or sink of CO.

This book is for students and academics in soil science. Presents state of the art in modeling soil-atmosphere-climate interactions and their use for generating scenarios of unprecedented magnitude in the area of C and N cycling in terrestrial ecosystems Provides quantitative information on the bi-directional exchange of carbon and nitrogen.

Soil organic carbon dynamics in ecosystem plays a great role in global carbon cycle and global change. With development of mathematical models that simulate changes in soil organic carbon, there have been considerable advances in understanding soil organic carbon by: 7.

To this end, it is necessary to implement a new modeling approach for tracking moisture in wetland soil. Once daily soil moisture profile of wetland soil is attained, model relationships are updated to simulate geochemical reactions and track concentrations of nitrogen (N) and carbon (C) related constituents in unsaturated wetland by: 6.

climate mitigation effects of soil carbon sequestration. Thus, soil organic carbon management has to be closely linked to efficient nutrient management. Soils are open systems and carbon inputs via biomass, like crop residues, is the prerequisite to maintain or enhance soil carbon stocks.

The transformation pathway of carbon. An integrated model WHCNS (soil Water Heat Carbon Nitrogen Simulator) was developed to assess water and nitrogen (N) management in North China.

It included five main modules: soil water, soil Cited by:   The soil samples were air-dried and sieved through 2-mm sieves (US Standard No. 10) to separate the sample into fine and coarse fractions.
