Soil nitrogen pool drives plant tissue traits in alpine treeline ecotones
2020, Forest Ecology and ManagementCitation Excerpt :Nitrogen content in fine roots and N:P ratios of twigs increased with the soil TN, NO3–-N, and N:P (Fig. 3), because fine roots transfer photosynthetic products and absorb available nutrients from the soil (Yuan et al., 2011; Ge et al., 2017), and twigs are responsible for leaves nutrient support and photosynthetic product output (Yang et al., 2014; Yan et al., 2016). All of these functions required the efficient participation of various enzymes (Tcherkez et al., 2006; Ge et al., 2010), which explained why plants and soil N stoichiometry connected. The concentration of NO3–- N in soil solution in the arid region is usually higher than NH4+-N because NH4+-N is easily oxidized to NO3–-N (Galloway et al., 2008; Hůnová et al., 2017).
Soil quality should be accurate evaluated at the beginning of lifecycle after land consolidation for eco-sustainable development on the Loess Plateau
2020, Journal of Cleaner ProductionCitation Excerpt :Thus, the limiting factors were SOM, CEC, nitrogen, available phosphorus, and enzyme activities. Many studies indicated that for both orchard and farmland, the content of SOM, nitrogen, and available phosphorus were generally less at Yan’an regions (Ge et al., 2010; Zhang et al., 2011). Unfortunately, these factors had a greater impact on reclaimed farmland, including the CEC and enzyme activities indicators.
Assessing the effect of heavy metals from the Novocherkassk power station emissions on the biological activity of soils in the adjacent areas
2017, Journal of Geochemical ExplorationCitation Excerpt :In meadow-chernozemic soils, positive correlations are found with both loosely and strongly bound HMs. Urease, which represents the class of hydrolases, plays an important role in the cycle of nitrogen (Calvarro et al., 2014; Ge et al., 2010; Hu et al., 2014; Margon et al., 2015; Nie et al., 2015). Inverse correlations were observed between the content of loosely bound metals and the activity of urease in alluvial and meadow-alluvial soils.
Soluble organic nitrogen pools in greenhouse and open field horticultural soils under organic and conventional management: A case study
2010, European Journal of Soil BiologyCitation Excerpt :Compared with the open fields, soil temperature will increase in the greenhouses, which will enhance microbial activity and decomposition of soil organic matter. Furthermore, Ge et al. [10] reported that the conversion of insoluble organic N to low molecular weight (LMW) SON (but not LMW-SON to NH4+ or NH4+ to NO3−) represents the main constraint to N supply. This may be expected as greenhouse cultivation management can accelerate the turnover of SON in soils.
