Effects of site preparation for afforestation on soil properties and greenhouse gas emission
(The University of Edinburgh, 2009)Forest plantations in the UK are often established on seasonally waterlogged peaty gley soils which often require site preparation (drainage and mounding) to lower the water table and prepare planting positions. Substantial ... -
Factors Influencing Methane (CH4) and Nitrous oxide (N2O) Emissions from Soils: A Review
(International Journal of Forest, Soil and Erosion, 2013-08)Methane (CH4 ) and nitrous oxide (N2O) are the two most important non-carbon dioxide (CO2 ) greenhouse gases (GHGs) that play a critical role in shaping the global climate. Their concentrations in the atmosphere have been ... -
