Abstract The character of pure or mixed forest canopies and their litterfalls contribute to different forest-floor properties. These organic layers also subjacent topsoil were studied at three study sites covered by treatments such as beech–spruce, beech–fir, spruce–fir two monospecific beech spruce treatments. age the stands ranged from 11 15 years when sampled. All used meadows afforested; th...

The use of the Mehlich-3 (M3) soil test procedure to assess plant availability numerous macro and micronutrients has become common at testing labs across US. is used for tests phosphorus (P) potassium (K) in Kansas; however, data other base cations existing methods are scarce Kansas soils. objective this study was investigate relationship between M3 ammonium acetate (AA) extractable calcium (Ca...

Soil cation exchange property (SCEP) is important in soil development and environmental buffering. However, the variations SCEP its correlation with soil-forming factors subsurface are not fully understood. In this study, we quantified surface as a function of parent material, vegetation, hillslope position, type. Fifty upland profiles from mid-subtropical China were selected. The capacity (CEC...

Pressure swing adsorption (PSA) technology is used in medical oxygen concentrators for selective of nitrogen under pressure from air to produce oxygen-enriched breathing. The functional material aluminosilicate zeolite like Li-13X, 5A (LTA) with a relatively high Al-content. It selectively adsorbs the into their molecular sieves due strong quadrupolar interaction between adsorbed and electrical...

Understanding the long-term effects of tree species on soil properties is crucial for development forest restoration policies in relation to choice that meet both environmental and local livelihood needs. This study was performed Arboretum Ruhande, Southern Rwanda, where monocultures 148 deciduous 56 conifer have been established 0.25 ha replicated plots from 1933 onwards. We investigated six e...
