Effects of Nitrate and Labile Carbon on Denitrification of Southern Temperate Forest Soils [PDF]

Chilean journal of agricultural research, 2010
The pressure for anthropogenic land use changes and logging of temperate forests in southern Chile is rapidly increasing, with its potentially high impacts on the capacity of soils to retain important limiting elements. We tested the hypotheses that logging increases the denitrification rates and nitrate and C limitation of denitrifiers activity would ...

Biochar Aged for Five Years Altered Carbon Fractions and Enzyme Activities of Sandy Soil

Land, 2023
Biochar applied to soil has been considered as an effective tool for mitigation of atmospheric carbon dioxide emission and enhancement of carbon storage in soil, which may also enhance soil quality.

Labile carbon in biological soil crusts in the Tabernas desert, SE Spain [PDF]

Soil Biology and Biochemistry, 2013
Decomposition processes are extremely important in biological soil crusts (BSCs). Although the effects of temperature and moisture on such processes have been widely studied, little is known about the influence of the readily metabolizable substrate (labile C) and how this substrate varies in different types of BSCs.

Effect of Biochar on Labile Organic Carbon Fractions and Soil Carbon Pool Management Index

Agronomy, 2023
Biochar is useful for soil organic carbon (SOC) sequestration. However, the effects of biochar aging and addition rates on SOC stabilization are unclear. A field experiment with four biochar application rates (0% (control), 1% (LB), 2% (MB), and 4% (HB) of dry fluvo-aquic soil) was conducted.

Biologically labile photoproducts from riverine non-labile dissolved organic carbon in the coastal waters

, 2015
Abstract. In order to assess the production of biologically labile photoproducts (BLPs) from non-labile riverine dissolved organic carbon (DOC), we collected water samples from ten major rivers, removed labile DOC and mixed the residual non-labile DOC with artificial seawater for microbial and photochemical experiments.
