2022, Science of the Total EnvironmentCitation Excerpt :However, long-term intensive agricultural practices have inevitably caused some environmental problems, such land degradation, soil erosion, non-point pollution, eutrophication, biodiversity loss and soil acidification (Dick, 1992; Gianfreda et al., 2005; Withers et al., 2014; Tsiafouli et al., 2015; Kosmas et al., 2016; Ouyang et al., 2016). Soil acidification is a common problem under long-term mineral fertilization in agriculture ecosystems (Guo et al., 2010; Goulding, 2016), particularly in tea garden soils (Hui et al., 2010). Soil acidification poses serious threats to the sustainability of agricultural systems.
National estimates of environmental thresholds for upland soil phosphorus in China based on a meta-analysis
2021, Science of the Total EnvironmentCitation Excerpt :For regions with low ETSP values and high P loss risks due to high SOM contents (e.g., northeastern China) (Liang et al., 2019), it is warranted to avoid excessive manure additions to limit soil P losses. However, due to dominance of smallholder farms in China, many farmers neglect the P content of the applied farmyard manure, resulting in excess P application relative to plant requirement (Wang et al., 2010b; Abe et al., 2016). Therefore, appropriate SOM levels in upland soils should be considered to balance agronomic benefits (i.e., soil fertility) and P loss risks in manure management practices.
Organic fertilizer reduced carbon and nitrogen in runoff and buffered soil acidification in tea plantations: Evidence in nutrient contents and isotope fractionations
2021, Science of the Total EnvironmentCitation Excerpt :However, in tea-producing countries, environmental problems associated with tea plantations, such as soil acidification and nitrogen leaching, are becoming apparent. High rates of chemical fertilizer application are likely to cause low fertilizer use efficiency and environmental pollution (Wang et al., 2010; Fu et al., 2012; Chen et al., 2017). The majority of previous studies mainly focused on soil nutrient concentration emissions caused by chemical fertilizer application, whereas few quantitative and accurate evaluations have been performed on the C and N change characteristics in tea plantation soil and runoff.
