Global change effects on humid tropical forests: Evidence for biogeochemical and biodiversity shifts at an ecosystem scale (2016, background): “In Hawaii and Panama, studies on highly weathered soils showed no responses of fine root biomass or root N concentrations to N fertilization after 5 and 14 years, respectively [Ostertag, 2001; Wurzburger and Wright, 2015].”
Foliar nitrogen and phosphorus accumulation responses after fertilization: an example from nutrient-limited Hawaiian forests (2010, background): “This pattern has been reported in several independent studies (Vitousek 1998; Cordell et al. 2001; Harrington et al. 2001; Treseder and Vitousek 2001) and has also been noted for roots (Ostertag 2001).”
A model of biogeochemical cycles of carbon, nitrogen, and phosphorus including symbiotic nitrogen fixation and phosphatase production (2007, methodology): “For the three LSAG sites, we used the estimates of N deposition and P weathering inputs from Vitousek [2004], and then varied the maximum NPP (UC,nf), and maximum uptake rates of soil mineral N (UN,nf) and P (UP,nf) by plants and allocation coefficients to approximate the observed size of C, N and P”
A meta-analysis of mycorrhizal responses to nitrogen, phosphorus, and atmospheric CO2 in field studies. (2004, background): “Root responses to N and P are more variable (Ostertag, 2001), so it is difficult to relate % colonization to mycorrhizal biomass in fertilization studies without specific data from each study.”
N : P ratios in terrestrial plants: variation and functional significance. (2004, background): “However, Ostertag (2001) reported opposite effects for Hawaiian forest: root turnover was slightly faster at the N-limited site than at the P-limited site and was increased by P fertilization.”
Nitrogen limitation of net primary productivity in terrestrial ecosystems is globally distributed. (2008, background): “In fact,N increasedBNPP (R¼1.47, n¼7,P¼0.03) among the four forests and three grasslands in which it was measured (Owensby et al. 1994, Ostertag 2001, Camill et al. 2004, Davis et al. 2004).”
Production and Resource Use Efficiencies in N- and P-Limited Tropical Forests: A Comparison of Responses to Long-term Fertilization (2001, methodology): “When we compare unfertilized plots, we see that the P-limited site had greater root biomass and density (Herbert and Fownes 1999; Ostertag 2001), lower root turnover rates (Ostertag 2001), higher total belowground carbon allocation (Herbert and Fownes 1999), and greater extracellular phosphatase…”
Contrasting Effects of Substrate and Fertilizer Nitrogen on the Early Stages of Litter Decomposition (2005, background): “Indeed, some studies have found positive correlations between litter P concentration and decomposition rate (Berg and others 1987; Vitousek and others 1994; Hobbie and Vitousek 2000; Ostertag 2001).”
Biological and Geochemical Sinks for Phosphorus in Soil from a Wet Tropical Forest (2004, background): “The lower horizon (A) ranged from 10 to 25 cm deep and had a lower root density (Ostertag 2001), greater bulk density, and higher mineral content (Table 1).”
