Gas diffusion can be used to quantify soil quality and structural development that is strongly affected by use management practices. There a lack of information about the quantitative effect tillage combined with crop sequences on structure. This study aimed effects bulk density, gas diffusivity, air-filled porosity, resulting pore continuity their dynamic during cropping cycle. A total 288 und...

Yellow River sediment is the potential resource for saline–sodic soil reclamation. Experiments of one-dimensional columns were conducted to investigate upward and downward water transportation characteristics mixed with different addition (0, 10, 20 kg/m2 in top cm layer). The saturated hydraulic conductivity, ratio macroporosity, cumulative capillary adsorption infiltration rate all increased ...

A thorough understanding of how conservation tillage in ̄uences water quality is predicated on knowledge of how tillage affects water movement. This paper summarizes the effects of conservation tillage on water movement and quality mainly based on long-term experiments on Luvisols at the North Appalachian Experimental Watershed near Coshocton, OH, USA. Conservation tillage can have a much larger...

Abstract In the basin of western China, four different kinds lithological reservoirs are developed, including low-permeability sandstone, sedimentary tuff, shale and volcanic rock. There is generally a large difference in micropore structure characteristics distribution laws due to reservoirs. The reserving capacity as well porous flowability, mechanism determined by hydrocarbon Low-temperature...

Porous organic molecular materials represent an emergent field of research in Chemistry and Materials Science due to their unique combination properties. To enhance performance expand the number applications, incorporation hierarchical porosity is required, as exclusive microporosity entails several limitations. However, integration macropores porous still outstanding challenge. Herein, we repo...
