Effects of conversion from leguminous acacia to non-leguminous eucalyptus on soil N<inf>2</inf>O emissions in tropical monoculture plantations
2021, Forest Ecology and ManagementCitation Excerpt :This result was different from those of several previous studies, which reported that soils in acacia stands emitted a larger amount of N2O than soils in eucalyptus stands (Dick et al., 2006; Li et al., 2010; Zhang et al., 2014). Studies have reported that eucalyptus stands generally have lower N input from litterfall (Bernhard-Reversat 1996; Forrester et al., 2005), slower N mineralization (Li et al., 2001; Tchichelle et al., 2017), and a smaller N pool in the litter (Voigtlaender et al., 2012; Tchichelle et al., 2017) than acacia stands, which should provide a smaller amount of N resources for N2O production in eucalyptus stands. In the present study, the N input from litterfall in the eucalyptus stands was much lower than that in the acacia stands (Table 1).
Litter and topsoil in Alnus subcordata plantation on former degraded natural forest land: A synthesis of age-sequence
2018, Soil and Tillage ResearchNitrogen dynamics in a nutrient-poor soil under mixed-species plantations of eucalypts and acacias
2017, Soil Biology and BiochemistryCitation Excerpt :Faster rate of litter decomposition, thus higher nitrogen release from decaying litter through mineralisation, may result in lower accumulation of soil organic N under acacia trees than under eucalypt trees (Bernhard-Reversat, 1996). Higher rate of N mineralisation under acacia trees than under eucalypt trees is commonly observed in tropical plantations (Bernhard-Reversat, 1996; Parrotta, 1999; Li et al., 2001; Voigtlaender et al., 2012). Faster turnover rate of N is thus expected in stands where acacia is planted either alone or in mixture.
Changes in above- and below-ground nitrogen stocks and allocations following the conversion of farmland to forest in rocky desertification regions
2016, Agriculture, Ecosystems and EnvironmentCitation Excerpt :In other words, the top-soil in karst areas of SW China constitutes the main reservoir for N in the overall ecosystem budget while the soil is vulnerable to natural or human-induced erosion and disturbance. Therefore, best management practices in plantations, as outlined in the GGP, need to be implemented to improve the soil quality and promote N storage (Bernhard-Reversat, 1996). The biomass nitrogen storage (both above-ground and below-ground parts) in Z. bungeanum plantations rapidly increased from 0.94 kg N ha1 for the 1-year-old stand to 262.12 kg N ha1 for the 10-year-old stand (Table 5).
Effects of tree species on topsoil properties and nitrogen cycling in natural forest and tree plantations of northern Iran
2016, CatenaCitation Excerpt :Scott and Binkley (1997) found that the net N mineralization was controlled by the forest litter fall quality by influencing the SOM quality. Increase in N mineralization has been ascribed by some authors to higher soil nutrient content and resulting lower tannin levels (Reversat, 1996). The results of this study showed that there is negative correlation between C and N mineralization.
