Modeling the carbon cost of plant nitrogen acquisition: Mycorrhizal trade‐offs and multipath resistance uptake improve predictions of retranslocation (2014, background): “The predicted fraction of net primary production allocated to N uptake was well within empirical estimates of root exudation and C allocation to mycorrhizae in forests [Brzostek et al., 2013; Hobbie, 2006].”
Stoichiometry constrains microbial response to root exudation- insights from a model and a field experiment in a temperate forest (2012, methodology): “These concentrations and the delivery flow rate were chosen to mimic rates of exudation observed for four temperate tree species in this region (Brzostek et al., 2012).”
Rhizosphere priming effects on soil carbon and nitrogen mineralization (2014, background): “Although many studies have reported positive rhizosphere effects on potential net N mineralization rate based on short-term lab incubations of root-free soils sampled from regions at different distance from live roots (e.g. Phillips and Fahey, 2006; Brzostek et al., 2013), a detailed N-budgeting ana”
Root-induced changes in nutrient cycling in forests depend on exudation rates (2014, unknown): “Hence, collecting exudates during only one (Smith, 1976) or two (Brzostek et al., 2013) time periods during the growing season may result in artificially low (or high) estimates.”
Rhizosphere priming: a nutrient perspective (2013, background): “First, in soils of low nutrient availability, inputs of energy-rich carbon compounds from roots may be used for the production of extra-cellular enzymes that can release nutrients locked in SOM (Asmar et al., 1994; Brzostek et al., 2012).”
Root exudates increase N availability by stimulating microbial turnover of fast-cycling N pools (2017, unknown): “…al., 2015), comparisons of N-cycling in the presence vs. absence of root inputs (Vitousek et al., 1982; Weintraub et al., 2007; Kaiser et al., 2011; Brzostek et al., 2013), and lab incubation studies of N transformations following additions of microbial substrates (Landi et al., 2006; Kieloaho et…”
Enzymes of importance to rhizosphere processes (2015, background): “Brzostek et al. (2013) showed that the exudation of”
