Soils contaminated with the oil (5-20 g/kg of soil) were purified by addn. of urea (N content 200 mg/kg soil) as well as of compost, bentonite, zeolite (concns. 3%, 2% and 2% by mass, resp.) and CaO (dose equiv. to 1 full hydrolytic acidity). Soils with or without the ...

and it is thought that the temperature sensitivity of decomposing organic matter in soil partly determines how much carbon will be transferred to the atmosphere as a result of global warming1. Giardina and Ryan2have questioned whether turnover times of soil carbon depend on temperature, however, o...
1) soil organic carbon content 土壤有机碳含量1. For analyzing the changes of SOC in 1980-82 and again in 2000,the soil organic carbon content of these samples were analyzed respectively. 通过对我国北方黄淮海平原区、黄土高原区和东北区三个主要农业生态区典型区县土壤有机碳含量的测定, 并与二次...
Soil aggregates are the basic units of soil structure, and their composition and carbon (C) stability directly affect soil fertility. As cementing agents, humic substances play an important role in the formation and stability of soil aggregates. Long-ter
BEIJING, Nov. 23 (Xinhua) -- A group of Chinese researchers issued a data map of the soil organic carbon (SOC) content for global black soil regions, shedding light on the quantification of agro-ecosystems and global food security, according to the recent issue of the journal Remote Sensing...

Soil aggregation is one of the most important factors affecting soil organic carbon (SOC) stabilization, and the stability of aggregates depends in part on soil microbial diversity and composition. Interactions between the soil bacterial community and SOC content in soil aggregates after afforestation ...
Therefore,it is very important to increase the organic carbon content in loessal soil and aeolian soil in ecological reconstruction on the Loess Plateau in the future. 展开 关键词: soils soil organic carbon density soil organic carbon storage the Loess Plateau ...
Abstract The world’s soils store more carbon than is present in biomass and in the atmosphere1. Little is known, however, about the factors controlling the stability of soil organic carbon stocks2,3,4and the response of the soil carbon pool to climate change remains uncertain5,6. We invest...
