Soil CO2 and CH4 fluxes in cropland agroforestry and monoculture systems

This data set includes data on soil Soil CO2 and CH4 fluxes, soil temperature, water-filled pore space, and mineral N (NH4+ and NO3-) measured at three sites in Germany, where the agroforestry systems combined crop rows and hybrid poplar short rotation coppices. We systematically compared soil Soil CO2 and CH4 fluxes between cropland agroforestry and monoculture systems over two years following different crop rotations and fertilization rates at each site. Each site is represented by 4 replicates per land use, at the following distances from the tree row for agroforestry: 1 m, 7 m and 24 m. Research domain: Soil Sciences Research question: In present, no systematic comparison was conducted of soil Soil CO2 and CH4 fluxes between cropland agroforestry and monoculture systems in temperate Europe

Research question: Agroforestry system is gaining increasing interests due to its potential to enhance carbon (C) sequestration and mitigate greenhouse gas (GHG) emissions in agriculture. To date, the effects of agroforestry on the spatial-temporal dynamics of soil carbon dioxide (CO2) and methane (CH4) fluxes are still poorly qualified.
