Phaeozem in einigen trockenen Alpentälern der Schweiz
Zeitschrift für Pflanzenernährung und Bodenkunde, 1980AbstractDer Begriff des Phaeozems wurde im Zusammenhang mit der Weltbodenkarte der FAO‐Unesco eingeführt. Kennzeichnend für diesen Boden ist der diagnostische Mullhorizont, der nach Gefüge, Farbe, Gehalt an Kalziumionen und organischem Kohlenstoff, sowie nach Mächtigkeit usw.

[Cu adsorption by phaeozem and burazem].
Ying yong sheng tai xue bao = The journal of applied ecology, 2003Studies on the thermodynamics and kinetics of copper (Cu2+) adsorption by phaeozem and burozem showed that that the adsorption of Cu2+ by these two soils was increased with the increasing concentration of Cu2+ within the range of Cu2+ concentrations used in the experiment, but the amount of Cu2+ adsorbed and fixed on phaeozem was much higher than that ...

Analysis on agro-ecological landscape pattern in Phaeozem land area in Northeast China
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004The spatial structure of landscape is the result of complicated interaction among nature conditions, living organisms and human activities, which changes reflect the interrelationship among them. With remote sensing (RS) images in the same season of different years, we can get the generalized and visualized information of landscape and its changes ...

Partition and characterization of cadmium on different particle-size aggregates in Chinese Phaeozem
Geoderma, 2013Organic-mineral complexations can be isolated from bulk soil by physical disaggregation followed by density fractionation for further examination of the patchy nature of aggregates distributed in soil. Phaeozem, which is a specific regional soil in China with high organic matter, was selected for fractionation into particle-size aggregates with clay ...

[Comparison on desorptive behavior of cadmium in phaeozem and burozem].
Huan jing ke xue= Huanjing kexue, 2007Desorptive behavior of Cd2+ was comparatively studied by the batch method on the two typical soils in northeast China. The results indicated that the two soils exhibit statistically significant sorption-desorption hysteresis. Phaeozem has a longer hysteresis period than the Burozem.

[Comparison on desorptive behavior of copper in phaeozem and burozem].
Huan jing ke xue= Huanjing kexue, 2006Desorptive behavior of Cu2+ from phaeozem and burozem was studied and compared using the batch method. The results indicated that Cu2+ desorbed from phaeozem tested had a longer lag period than that from burozem. When adsorbed Cu2+ for phaeozem was lower than 729.00 mg x kg(-1) (Cu2+ concentration was lower than 40 mg x L(-1)), and on burozem was lower

Soil carbon sequestration of Chinese Loess Plateau and Northeast Phaeozem Region
2011 International Conference on Electrical and Control Engineering, 2011Both Loess Plateau and Northeast Phaeozem Region of China are main ecologically fragile regions in China. The unique climate conditions and intensified human activities may alter the soil organic carbon (SOC) content in these regions, and hence affect the carbon cycle of terrestrial ecosystem and climate change.

Waste Management, 2009
The use of organic wastes in agriculture may increase the production of crops by incorporating organic matter and nutrients into the soil, and by improving its physical characteristics; however, this use may cause environmental problems such as the leaching of certain ions.

The relation between the content of organic phosphorus and latitude in Northeast China phaeozem
Biology and Fertility of Soils, 2005Top phaeozem samples were collected from Nenjiang County (in Heilongjiang province) to Changtu County (in Liaoning province) in Northeast China every 6 km by using global positioning system (GPS) and analyzed for their content of organic C, total N, total P, organic P, and the organic to inorganic P (Po/Pi) ratio.
