Abstract Nitrogen‐rich tropical/subtropical forest soil acts as a terrestrial source of nitrous oxide (N 2 O), greenhouse gas commonly affected by nitrogen availability and moisture. However, in tropical subtropical regions experiencing both elevated deposition altered precipitation regimes, it is unclear whether regimes have interactive effects on N O emissions what roles O‐associated nitrifiers/denitrifiers play these interactions. We conducted year field study evergreen broadleaf southern...
The effects of intensive nitrogen (N) fertilizations on spatial distributions soil microbes in bioenergy croplands remain unknown. To quantify N fertilization effect heterogeneity microbial biomass carbon (MBC) and (MBN), we sampled top mineral horizon soils (0-15 cm) using a spatially explicit design within two 15-m2 plots under three treatments three-year long experiment Middle Tennessee, USA. were no input (NN), low (LN: 84 kg ha-1 urea) high (HN: 168 urea). crops switchgrass (SG: Panicum...
Abstract Nitrogen (N) fertilizers can potentially alter spatial distribution of soil organic carbon (SOC) and total nitrogen (TN) concentrations in croplands such as switchgrass (SG: Panicum virgatum L.) gamagrass (GG: Tripsacum dactyloides L.), but it remains unclear whether these effects are the same between crops under different rates fertilization. 13 C 15 N two important proxy measures biogeochemistry, they were rarely examined to their distributions soil. Based on a three-year long...
