density ranged between 0 to 1.78 kg·m-2.(3) The soil organic carbon content and density in forest land decreased with increasing altitude,and those in urban construction land and unused land were very low.(4) The land use change could affect the storage and distribution of soil organic ...
The density of soil is crucial in engineering, construction, and research. Standard methods to determine density use procedures, equipment or expendable materials that limit their effectiveness in challenging field conditions. Some methods require burdensome logistics or have time requirements that limit ...
The relative density of lunar soil The specific gravity and minimum and maximum bulk densities were determined for three one-gram lunar soil samples containing particles less than 1 mm in diameter: 14163,148; 14259,3; and 15601,82. The specific gravity varied from 2.90 to... WDI Carrier,JK...
Soil scientists and engineers commonly require bulk density (Db) data as parameter input of simulation models predicting a wide range of soil processes. Field methods exist to measure Db, but are labor intensive and time consuming. Much effort has been recently devoted to evaluate alternative proced...
A METHOD OF MEASURING THE BULK DENSITY OF SMALL SOIL CONGLOMERATES. APPLICATION TO THE ANALYSIS OF POROUS SOIL SYSTEMS THE IN-SITU ANALYSIS OF THE HETEROGENEOUS POROSITY OF SOIL REQUIRES THE MEASUREMENT OF BULK DENSITY ON SMALL CONGLOMERATES. A MEASURING TECHNIQUE, IN WHICH... G Monnier,P Stengel...
In a 2-year study we investigated soil macro-arthropods (Opilionida, Araneida, Pseudoscorpionida, Isopoda, Diplopoda, Chilopoda, Coleoptera) in a forest where forestry management is nature oriented and includes the accumulation of about 10 m 3 deadwood per ha. We focused on soil arthropod densi...
Particle density of soils is defined by the ratio of soil particle mass and soil particle volume. Depending on soil types, the range of variation of soil particle density varies not significantly, i.e. by 4%. Therefore, it may not be worthwhile to order laborator...
The aim of this study was to assess the influence of different long-term agricultural practices on the mineralogical, physical and micromorphological composition of soils along the Austrian-Hungarian border, where Austrian and Hungarian agricultural soils (3 transects with different soil type and cultiv...
Controlling livestock grazing density and implementing environmental restoration are important measures for soil andconservation in Iceland. 控制放牧密度和开展环境修复是冰岛最主要的水土保持措施. 来自期刊摘选 20. Enclosure Gel filled, ultrasonically welded, high density ABS housing. 附胶体填充, 超声焊接, 高...
