Tree windbreaks are an attractive multiple-benefit land use through their ability to mitigate climate change by modifying the local microclimate to improve crop growth and by sequestering carbon in the soil and tree biomass. Recently, such agroforestry practices are also being considered for their bioenergy potential as the wood could be harvested for direct combustion, cellulose to ethanol conversion, or pyrolysis to bio-oils. The objective of this project was to use detailed soil profile descriptions and spatially-distributed soil sampling to determine the soil carbon sequestration potential of tree plantings across climatic gradients in the Central Russian Uplands and the U.S. Great Plains. Three Russian sampling locations, Streletskaya, Yamskaya, and Kamennaya spanned a gradient of mean annual temperature from 5.3 to 5.8 °C and precipitation from 480 to 580 mm. Three U.S. sampling locations, Reynolds, North Dakota; Huron, South Dakota; and Norfolk, Nebraska; had ranges of annual temperature from 3.9 to 9.2°C and precipitation from 450 to 690 mm. Tree species at the sampling sites included black poplar (Populus nigra), silver birch (Betula pendula), box elder (Acer negundo), English oak (Quercus robur) and balsam poplar (Populus balsamifera) in Russia and green ash (Fraxinus pennsylvanica), redcedar (Juniperus virginiana), Siberian elm (Ulmus pumila, L.), mulberry (Morus ... 전체 초록 보기
