Review of soil dissolved organic nitrogen cycling: Implication for groundwater nitrogen contamination
2024, Journal of Hazardous MaterialsShallow groundwater fluctuation: An ignored soil N loss pathway from cropland
2022, Science of the Total EnvironmentCitation Excerpt :Soil moisture of 50% to 70% was found as the optimal water state for nitrification, while the moisture content beyond or below these values was unfavorable for the nitrification process (Qian and Cai, 2010). In addition, the drying process also increased the DON in the soil, which was consistent with the findings of Song et al. (2015). This may be related to the destruction of soil aggregates (Denef et al., 2001) or microbial cell lysis (Gordon et al., 2008).
Drainage and leaching losses of nitrogen and dissolved organic carbon after introducing maize into a continuous paddy-rice crop rotation
2017, Agriculture, Ecosystems and EnvironmentCitation Excerpt :On the one hand, this enhanced mineralization could improve the N-availability, but on the other hand it could increase nitrate leaching and the emission of N2O (Weller et al., 2015, 2016; Kögel-Knaber et al., 2010). Nitrogen losses under paddy-rice–wheat rotations have been well investigated (Song et al., 2015; Zhao et al., 2009; Wang et al., 2007; Pande and Becker, 2003). In principle, soil processes under paddy-rice–maize systems should be comparable to such paddy-rice–wheat systems (Timsina et al., 2010).
Biological responses of wheat (Triticum aestivum) plants to the herbicide simetryne in soils
2016, Ecotoxicology and Environmental SafetyCitation Excerpt :Not surprisingly, owing to the massive use, s-triazines and their metabolites were found to accumulate in soils and aquatic systems in alarmingly high concentrations (Xu et al., 1989; Schottler et al., 1994; Thurman et al., 1994; Bonora et al., 2013). The rotation of rice and wheat is widely used and highly endorsed for its capacity to resolve the obstacles of continuous cropping, increase crop yields significantly, inhibit diseases, and improve soil microbial community construction (Dawe et al., 2004; Devkota et al., 2015; Song et al., 2015; Wang et al., 2015). In China, simetryne is commonly applied to control weeds in rice–wheat rotation systems.
