Impact of inorganic nitrogen additions on microbes in biological soil crusts (2015, background): “N saturation (excess N) may factor into the microbial responses, which are rarely linear (Ramirez et al., 2012), and the driving factors are therefore difficult to identify independently.”
Responses of soil bacterial and fungal communities to extreme desiccation and rewetting (2013, background): “Several studies have documented the oligotrophic life-strategy of Acidobacteria and Verrucomicrobia, contrasting with the copiotrophic Actinobacteria, along soil carbon and nitrogen availability gradients (Fierer et al., 2007; Nemergut et al., 2010; Fierer et al., 2012; Ramirez et al., 2012).”
Plant nitrogen uptake drives rhizosphere bacterial community assembly during plant growth (2015, background): “…flexibility of soil bacteria (Anderson et al., 2005; Cherif and Loreau, 2013), rapid shifts in N availability within the rhizosphere resulting from plant nutrient uptake could strongly alter soil bacterial community structure (Hessen et al., 2004; Ramirez et al., 2012; Sardans et al., 2012).”
Forest Soil Bacteria: Diversity, Involvement in Ecosystem Processes, and Response to Global Change (2017, background): “A decrease in oligotrophic bacteria is often found concomitantly with a decrease in the activity of enzymes related to cellulose breakdown, again supporting the hypothesis that the addition of N negatively affects microbial SOM decomposition (262, 264).”
Consistent responses of soil microbial communities to elevated nutrient inputs in grasslands across the globe (2015, result): “Overall, the taxonomic patterns in our cross-site study were in agreement with previous work conducted at individual grassland sites (20), and they corroborate laboratory studies that have noted similar shifts in the relative abundances of these major bacterial groups with nutrient additions (13).”
Soil microbial community and network changes after long-term use of plastic mulch and nitrogen fertilization on semiarid farmland (2021, background): “Additionally, high N input resulted in loss in the bacterial diversity, thereby causing adverse effects on soil function (Ramirez et al., 2012).”
