Root-induced changes in nutrient cycling in forests depend on exudation rates (2014, positive): “, 2007), girdling and pulse labeling studies indicate that exudate fluxes are also driven by source-sink relationships (Phillips et al., 2008; Kaiser et al., 2010).”
Root carbon inputs to the rhizosphere stimulate extracellular enzyme activity and increase nitrogen availability in temperate forest soils (2011, methodology): “Our inability to resolve species and seasonal differences in exudation rates is probably the result of infrequent sampling and high inherent spatiotemporal variability in exudate fluxes (Phillips et al. 2008).”
The rhizosphere microbiome: significance of plant beneficial, plant pathogenic, and human pathogenic microorganisms. (2013, background): “Another bottleneck is the potentially high variability of root exudation across environments, soil types, and plant physiological conditions such as growth stage (Sandnes et al., 2005; Dessureault-Rompre et al., 2006, 2007; Phillips et al., 2008; Shi et al., 2011).”
The Role of Soil Microorganisms in Plant Mineral Nutrition—Current Knowledge and Future Directions (2017, methodology): “Various studies have described analyses of plant root exudates, with Phillips et al. (2008) developing a method to collect exudates from mature trees in the field, although microbial metabolism probably makes a significant impact upon this non-sterile system.”
Enhanced root exudation induces microbial feedbacks to N cycling in a pine forest under long-term CO2 fumigation. (2011, methodology): “Exudates were collected every 4–8 weeks from April 2007 to October 2009 using a culture-based cuvette system developed specifically for loblolly pine roots at this site (Phillips et al. 2008).”
