Nitrogen alters carbon dynamics during early succession in boreal forest
Boreal forests are an important source of wood products, and fertilizers could be used to improve forest yields, especially in nutrient poor regions of the boreal zone. With climate change, fire frequencies may increase, resulting in a larger fraction of the boreal landscape present in early-successional stages. Since most fertilization studies have focused on mature boreal forests, the respons...
متن کاملSummary Soil nitrogen can alter storage and remobilization of carbon and nitrogen in forest trees
of carbon and nitrogen in forest trees and affect growth responses to elevated carbon dioxide concentration ([CO2]). We investigated these effects in oak saplings (Quercus robur L.) exposed for two years to ambient or twice ambient [CO2] in combination with low(LN, 0.6 mmol N l) or high-nitrogen (HN, 6.1 mmol N l) fertilization. Autumn N retranslocation efficiency from senescing leaves was less...
متن کاملCarbon : nitrogen stoichiometry in forest ecosystems during stand developmentgeb
Results The C : N ratio in plant tissue, litter, forest floor and mineral soil exhibited large variation across various sequences, with an average of 145.8 9.4 (mean SE), 49.9 3.0, 38.2 3.1 and 18.5 0.9, respectively. In most sequences, the plant tissue C : N ratio increased significantly with stand age, while the C : N ratio in litter, forest floor and mineral soil remained relatively constant...
متن کاملSoil warming, carbon-nitrogen interactions, and forest carbon budgets.
Soil warming has the potential to alter both soil and plant processes that affect carbon storage in forest ecosystems. We have quantified these effects in a large, long-term (7-y) soil-warming study in a deciduous forest in New England. Soil warming has resulted in carbon losses from the soil and stimulated carbon gains in the woody tissue of trees. The warming-enhanced decay of soil organic ma...
