Adequate acquaintance of soil organic carbon density( SOCD) and soil organic carbon storage( SOCS) are of practically significance for large-scale ecological construction. In this paper,SOCD and SOCS in topsoil( 0- 20 cm) of different soils on the Loess Plateau were estimated based on the data...
Applications of the random-packing model may delineate surface-sealing susceptibility among soils of similar texture, describe the degree of profile devlopment among soils of different orders, and delineate soil profiles or horizons within a profile to pan formation susceptibility....
The oppression of soil invertebrate.fauna in pine forests and meadows with high levels of radionuclides and heavy metals is revealed. Also shown is the decrease in the number and density of different taxonomic groups of invertebrates, reduction of the diversity and spectrum of trophic groups and ...
Organic matter and physicochemical attributes of a cambisol under different agricultural uses in a semi-arid region of Brazil. In semiarid environments, it is possible to verify the fragility of soils in terms of decompos...
The potential effects of these metals on environment and agricultural activities were also assessed. Results indicated that the major sources for the metals’ contamination are emissions from vehicles. High and medium traffic volume impacted more metals of the soils. Zinc, Cu, Cd, and Cr were ...
It is suggested that S can be used as an index of soil physical quality that enables different soils and the effects of different management treatments and conditions to be compared directly. 展开 关键词: Compaction Density Organic matter Root growth Texture Water retention curve ...

Nicholson, in Soil Improvement and Ground Modification Methods, 2015 5.6.1.1 Density Control Tests The two components required to calculate density are volume and dry weight. Traditionally...
It is suggested that reduced plant growth in response to compaction may be occurring at lower bulk density in soils derived from volcanic parent material than those usually reported. 展开 关键词: soil bulk density ryegrass cultivar Lolium perenne mechanical impedance soil compaction root length ...
1). In some exception of rocky part, the area is well covered with vegetation. Tree occurs on most of soils although they are rather sparse and small on many of the bog lands. The usual site for the trees are: Black spruce (Picea mariana) and tamarack in the swamps (peatlands), ...
It is suggested that S can be used as an index of soil physical quality that enables different soils and the effects of different management treatments and conditions to be compared directly. Introduction Soil quality is a subject that is receiving increasing attention (e.g., Wilson and Mali...
