“…Sites with greater reserves of soil organic matter and nutrients and a favorable climate for plant growth are likely to be more resilient to biomass removals than sites lacking these characteristics. Residue retention can conserve nutrients by reducing nutrient losses from leaching (Blumfield and Xu 2003, Carlyle et al 1998, Jurgensen et al 1992.…”

“…Residue retention in a radiata pine (Pinus radiata D. Don) stand resulted in 43 percent more total N mineralized over 4 years, but much of the mineralized N leached below the rooting zone (Smethurst and Nambiar 1990). In subtropical Australia, retention of residues resulted in reduced net N mineralization and N loss from leaching for 2 years after harvest (Blumfield and Xu 2003). Doubling the amount of harvest residues increased nonsymbiotic N-fixation by 73 percent on conifer sites in the northern Rocky Mountains during 2 years after harvesting (Jurgensen et al 1992).…”

“…Residue retention usually contributes to the conservation of soil water although effects can be short lived and restricted to the upper soil layers (Blumfield andXu 2003, O'Connell et al 2004). Residue retention can also significantly moderate surface soil temperatures.…”

“…Hoop pine (Araucaria cunninghamii) is an N demanding, indigenous Australia softwood species with plantations currently covering about 45,000 ha in Southeast Queensland, Australia (Mathers et al 2003;Blumfield et al 2005;Xu et al 2008b). The typical rotation length of hoop pine plantations is about 50-60 years, and all current harvesting is of first rotation (1R) plantations and plantings are on second rotation (2R) sites (Pu et al 2001(Pu et al , 2002Blumfield and Xu 2003;Blumfield et al 2005). Many researchers studied soil microbial biomass in early stages of hoop pine plantation (Chen et al 2003) or effects of residue management on soil mineral N dynamics (Pu et al 2001(Pu et al , 2002Blumfield and Xu 2003).…”

Background, aim, and scope Hoop pine (Araucaria cunninghamii) is a nitrogen (N) demanding indigenous Australia softwood species with plantations in Southeast Queensland, Australia. Soil fertility has declined with increasing rotations and comparison study of N cycling between hoop pine plantations, and adjacent native forest (NF) is required to develop effective forest management for enhancing sustainable forest production and promoting environmental benefits. Field in situ mineral 15 N transformations in these two forest ecosystems have not been studied. Hence, the present study was to compare the differences in soil nutrients, N transformations, 15 N fluxes, and fate between the hoop pine plantation and the adjacent native forest. Materials and methods The study sites were in Yarraman State Forest (26°52′ S, 151°51′ E), Southeastern Queensland, Australia. The in situ core incubation method was used in the field experiments. Mineral N was determined using a LACHAT Quickchem Automated Ion Analyzer. 15 N were performed using an isotope ratio mass spectrometer with a Eurovector elemental analyzer. All statistical tests were carried out by the SPSS 11.0 for Windows statistical software package.Results Soil total C and N were significantly higher in the NF than in the 53-year-old hoop pine plantation. Concentrations of NO 3 -were significantly higher in the NF soil than in the plantation soil. The plantation soil had significantly higher 15 N and 13 C natural abundances than the NF soil. The NF soil had significantly lower C/N ratios than the plantation soil. NO 3 --N was dominated in mineral N pools in both NF and plantation soils, accounting for 91.6% and 70.3% of the total mineral N pools, respectively. Rates of net nitrification and net N mineralization were, respectively, four and three times higher in the NF soil than in the plantation soil. The 15 NO 3 --N and mineral 15 N were significantly higher in the NF soil than in the plantation soil. Significant difference in 15 NH 4 + -N was found in the NF soil before and after the incubation. Discussion The NF soil had significantly higher NO 3 --N, mineral N, total N and C but lower δ 15 N, δ 13 C, and C/N ratios than the plantation soil. Moreover, the rates of soil net N mineralization and nitrification were significantly higher, but ammonification rate was lower in the NF than in the plantation. The NF soil had many more dynamic N transformations than the plantation soil due to the combination of multiple species and layers and, thus, stimulation of microbial activity and alteration of C and N pool sizes in favor of the N transformations by soil microbes. The net rate of N and 15 N transformation demonstrated differences in N dynamic related to the variation in tree species between the two ecosystems.Conclusions The change of land use and trees species had significant impacts on soil nutrients and N cycling processes. The plantation had larger losses of N than the

“…E. globulus bark showed a clearer tendency to immobilize N than the other residues despite its lower decomposition rate. Nevertheless the N immobilization produced during decomposition of harvest residues can have a positive effect in terms of N economy, preventing mineralized N to be leached through the soil profile (Blumfield & Xu, 2003).…”
