Effects of biochar and dicyandiamide combination on nitrous oxide emissions from Camellia oleifera field soil.

Greenhouse gas emissions from agricultural soils contribute substantially to global atmospheric composition. Nitrous oxide (NO) is one important greenhouse gas induces global warming. Nitrification inhibitors (NI) or biochar can be effective soil NO emission mitigation strategies for agricultural soils.

[Carbon, nitrogen and phosphorus contents and their ecological stoichiometry in litters and soils on meadow of Wugong Mountain, Jiangxi, China at different altitudes.].

Carbon (C), nitrogen (N) and phosphorus (P) contents and ecological stoichiometry and their correlations of litter and soil along 1500-1900 m on Wugong Mountain meadow were studied. The results showed that litter C, N and P contents varied in the range of 397.5-458.
