Wilkinson Soil Organic C and N Pools under Long-term Pasture Management in the Southern Piedmont USA. (... a comparison of the effectiveness of long-term land management practices for retaining carbon [C] and nitrogen [N] in the soil [rather than having it enter the atmosphere and possibly contribute to the build-up of greenhouse gases leading, potentially, to global warming and climate change]. Retaining the C and N in the soil also helps to sustain and improve soil fertility. The authors compared the C and N pools under pastures which differed in ways such as management practices, plant composition, the length of time the land had been a pasture, what the land had been used for previously, and then those results were compared with other land uses. The authors discovered that grazed [by cattle] pasture land covered with tall fescue-common bermudagrass contained greater amounts of carbon and nitrogen in the soil than pasture land with similar plant cover that was maintained by haying [conservation tillage cropland]. In fact, the storage of C in the soil under long-term grazed land was nearly equal to that under forested land, and the storage of N in the soil under these conditions was much greater than that found under forested land. The authors conclude that properly grazed pastures in the Southern Piedmont USA have great potential to restore natural soil fertility, sequester soil organic C and N and increase soil biological activity and in the long-term, grass management systems have nearly equivalent potential to store soil organic C as forestland -- from the abstract and text of the article) Soil Biology and Biochemistry Volume 32, Number 4 (April 2000): 469-478. **An abstract of this article is currently available through the Web site of Soil Biology and Biochemistry** How to find the above journals, magazines, and other publications?
