In Summary

Soil OC is a significant source and sink of atmospheric CO2

Soil is a complex, biologically active medium

Soil OC is not one material

Changes in SOC can be measured directly or can be modelled

The C sink value of soils is limited BUT increasing and maintaining SOC has many benefits for improved productivity and soil resilienceMysneakers | Patike

Introduction:
The Southeastern Coastal Plain in the United States is a major agricultural production area; however, soils are typically low in cation exchange capacity (CEC), nutrient content, and organic carbon content. For example, Tifton

On highly weathered soils in tropical and subtropical climates, maintenance of soil organic matter is essential to sustain system productivity and avoid rapid soil degradation. But climatic conditions as well as soil characteristics favor the rapid decomposition of organic matter. However, several recent studies indicated that black carbon, the product of incomplete combustion of organic material, could combine characteristics highly beneficial for soil nutrient dynamics with high stability against chemical and microbial breakdown.
