Plant respiration | Carbon Tree

http://www.carbontree.fi/articles/plant-respiration

Skip to main content. The importance of forests. Year in a forest. Lifetime of a forest. Plant needs energy for growth, transport and maintenance of vital functions as animals do. To get the energy required, they oxidize (i.e. burn the photosynthetically fixed sugars). At the same time, water and carbon dioxide are released as waste products. Respiration occurs in all living plant parts (i.e. in the leaves, trunk and roots). Department of Forest Sciences.

Photosynthesis | Carbon Tree

http://www.carbontree.fi/articles/photosynthesis-0

Skip to main content. The importance of forests. Year in a forest. Lifetime of a forest. Photosynthesis is the most fundamental process in plants because it provides raw material for growth and stores energy for later use in vital functions. In photosynthesis, the energy of solar radiation is converted into chemical form using atmospheric carbon dioxide and soil water. Meanwhile, oxygen is released into the air. The exchange of gases between the plant and the atmosphere happens via the stomata.

Abiotic environmental factors | Carbon Tree

http://www.carbontree.fi/articles/abiotic-environmental-factors

Skip to main content. The importance of forests. Year in a forest. Lifetime of a forest. The movements of Earth in relation to the Sun generate a strong annual cycle of radiation and temperature that further affects other environmental factors such as soil moisture and air humidity. Environmental factors affect physiological processes and therefore, identification and understanding of their nature is needed in order to understand and predict the biological actions of a forest.

Skip to main content. The importance of forests. Year in a forest. Lifetime of a forest. Metod för att mäta markrespirationen är ganska enkel. Vi satt kammaren på market och följer med hur koldioxidhalten förändras i kammarens luftrum. Om markvegetation binder koldioxid till sig, koldioxidhalten sjunker i kammaren. Koncentrationen stiger däremot eftersom växter och marken samtidigt andas ut koldioxid. Department of Forest Sciences.

How to model soil respiration? | Carbon Tree

http://www.carbontree.fi/articles/how-model-soil-respiration

Skip to main content. The importance of forests. Year in a forest. Lifetime of a forest. How to model soil respiration? REW stands for Relative Extractable Water , and it refers to the amount of water in the soil available to plants and soil microfauna. Soil microbes that decompose soil organic matter function in soil water. In drying soil, the microbes have more difficulty accessing soil organic matter and the decomposition process gets slower. Root respiration also declines in very dry soil.

Skip to main content. The importance of forests. Year in a forest. Lifetime of a forest. Years of measurements have produced a lot of information on plant respiration. We know more or less how the respiration rate is related to the changing environmental conditions. In principle, respiration exponentially follows temperature. The temperature dependence, however, decreases in low soil water (REW). R = Max { 0, f(REW) * r. R means the rate of respiration (i.e. the CO. F(REW)= Min {1, Max { 0, (REW d.

Skip to main content. The importance of forests. Year in a forest. Lifetime of a forest. The carbon bound in net primary production is eventually transferred to the soil in litter fall, root turnover and death of individual plants. In addition, trees notably allocate carbon to the root systems for root growth and root maintenance. Carbon is also added to the forest floor from leaching of dissolved organic matter from the canopy. In our studies we have observed that the annual CO.
