[Comparison on desorptive behavior of cadmium in phaeozem and burozem].

Huan jing ke xue= Huanjing kexue, 2007
Desorptive 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, 2006
Desorptive 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

Nitrate and phosphate leaching in a Phaeozem soil treated with biosolids, composted biosolids and inorganic fertilizers

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.

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), 2004
The 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 ...

Determination of spatial variability of some magnesium forms in Phaeozem using geostatistical methods

Journal of Elementology, 2014
The spatial variability analysis of soil properties facilitates the prediction of their contents across various sites, useful for design of site-specific farming practices. Intrapopulation and spatial variation of soil available (Mg-A), exchangeable (Mg-E) and water-soluble (Mg-H2O) magnesium forms was evaluated in a field on Phaeozem soil, located in ...

[Combined ecological effects of acetochlor and copper sulphate on microorganisms in phaeozem].

Huan jing ke xue= Huanjing kexue, 2008
In order to explore the combined ecological effects of acetochlor and copper sulphate on soil microorganisms, the traditional toxicological methods and BIOLOG were employed. The results indicate that the combined application of acetochlor and copper sulphate has acute inhibitory effects on the amount of culture-dependent viable bacteria, actinomycetes ...

[CH4 and N2O emissions from phaeozem rice field and their mitigative measures].

Ying yong sheng tai xue bao = The journal of applied ecology, 2004
Determinations on the CH4 and N2O emissions from phaeozem rice field showed that their emission amount in rice growing season was much lower than any other regions in China. There was trade-off relationship between CH4 and N2O emissions(r = -0.513, P < 0.05).

[Adsorption behavior and speciation transformation of Ag+ in phaeozem and red soil].

Huan jing ke xue= Huanjing kexue, 2011
The batch equilibration experiments were carried out to study the adsorption characteristics of Ag+ and the effect of pH on the adsorption process in two typical Chinese soils, which the phaeozem from Northeast China and the red soil from Hunan province.

[Effects of methamidophos and copper on ecological detoxification of acetochlor by earthworm in phaeozem].

Ying yong sheng tai xue bao = The journal of applied ecology, 2007
By using microcosm culture method, this paper studied the dynamic changes of acetochlor degradation by earthworm in phaeozem with methamidophos or copper addition, aimed to approach the feasibility of using earthworm to intensify the detoxification of acetochlor.
