2011-10-18Increased Phosphorus Availability Mitigates the Inhibition of Nitrogen Deposition on CH4 Uptake in an Old-growth Tropical ForestMore and more studies indicate that,nitrogen deposition inhibites forest soil methane(CH4)uptake. MO Jiangming from ecosystem management group of South China Botanical Garden(SCBG).Recently,Dr. This work was guided by Prof. MO Jiangming from ecosystem management group of SCBG and Prof. This finding firstly revealed the effects of N/P interaction... More and more studies indicate that, nitrogen deposition inhibites forest soil methane (CH4) uptake. Consequently, nitrogen (N) deposition increases atmospheric CH4 concentration due to weaken the function of forest soil as CH4 sink. This standpoint has been supported by Dr. ZHANG Wei (Zhang et al., Journal of Geophysical Research-Atmospheres, 2...Read More
