The refractory nature of some portions of forest soil organic matter also provides the slow, gradual release of organic nitrogen and phosphorus to sustain long term forest productivity. Contemporary and future disturbances, such as climatic warming, deforestation, short rotation sylviculture, the invasion of exotic species, and fire, all place strains on the integrity of this homeostatic system of C, N, and P cycling. On the other hand, the CO2 fertilization effect may partially offset losses of soil organic matter, but many have questioned the ability of N and P stocks to sustain the CO2 fertilization effect. Despite many advances in the understanding of C, N, and P cycling in forest soils, many questions remain. For example, no complete inventory of the myriad structural formulae of soil organic N and P has ever been made. The factors that cause the resistance of soil organic matter to mineralization are still hotly debated. Is it possible to "engineer" forest soil organic matter so that it sequesters even more C? The role of microbial species diversity in forest C, N, and P cycling is poorly understood. The difficulty in measuring the contribution of roots to soil organic C, N, and P makes its contribution uncertain. Finally, global differences in climate, soils, and species make the extrapolation of any one important study difficult to extrapolate to forest soils worldwide.Biology, life sciencesbicsscpolyphenolsaluminum accumulatornear natural forest managementchloroform fumigation extractionsoil structuresoil enzymesmanure pelletingmicrobial biomassOxisolbiolabilitysoil nutrientssecond production cyclePLFApyrolysisEucalyptus sp.Cunninghamia lanceolata plantationcarbonthe Three Gorges Reservoirrevegetationcarbon distribution indexclimate changeseasonsannual increment averagetopographyhumic substanceslitter Nsoil fertilityclimate zonenutrient cyclingDaxing’an Mountainscarbon mineralizationnitrification31P nuclear magnetic resonance spectroscopy (31P NMR)organic matterthroughfallforest soildissolved organic carbon (DOC)P speciesstoichiometric homeostasisdissolved organic matter (DOM)soil organic matter fractionvariable-charge soilsammoniumnitratesoil degradationsoil P fractionsseasonal trendsammonia-oxidizing bacterianitrogen dynamicsnet primary productivitysoil microbial communitiesbeech forestssoil pHwood volumetemperaturenorthern temperatemultilevel modelsPinus massoniana plantationammonia-oxidizing archaeaP stockstand densityP resorption efficiencyforest typessoil greenhouse gas fluxenzyme activitiessoil Nalpine forestmoisture gradientclimateclimatic factorssoil available phosphorusmicrobial activitysoil available nitrogenleaf N:P ratiostemflowChamaecyparis forestcharcoalgross nitrogen transformationsprincipal component analysesinformation reviewmanuringstand agetree-DOMBiology, life sciencesQualls Robert G1322911ScCtBLLScCtBLLBOOK9910346854303321Carbon, Nitrogen and Phosphorus Cycling in Forest Soils3041169UNINA
