The results show that thepercentageof rock fragments in fallow plot is the highest and the percentageof rock fragments in wasteland is the smallest. Provided the percentage of rock fragments in the samples of wasteland was known at a normal value, and the soil textureindex was expressed with ...
With respect to the hydraulic properties, the cover beds vary mainly in texture, especially regarding coarse clasts, and bulk density (Kleber et al., 1998b). An important property, which is unique to rock that weathers to platy clasts, is its imbricate structure. This is the result of the...
The microbial community in the Florida soil is likely adapted to moisture extremes, since the field site regularly cycles between wet and moist, but its soils also drain well due to the sandy texture. Since these microbes are presumably adapted to moisture fluctuations, it is likely that this ...
Understanding the effects of plastic pollution in terrestrial ecosystems is a priority in environmental research. A central aspect of this suite of pollutants is that it entails particles, in addition to chemical compounds, and this makes plastic quite d
Usually, the pore water pressure varies with the groundwater level and pore air pressure varies with the environmental changes which create unsaturated soil conditions. The curve can be divided into three distinct stages- boundary effect stage, transition stage and residual stage. There is a drastic...
Still, earthworm distribution varies because of their species-specific traits and food preferences [4]. Earthworms feed on mineral soil and associated soil organic material (SOM), such as litter from fine roots, fallen leaves, and branches [5]. Hence, forests and grasslands that yield year-...
texture. Their surface area and influence on soil properties (nutrient and retention) is considered to be minimal. Sand particles lie between 2.00 and 0.05 mm: silt particles fall between 0.05 and 0.002 mm:and clay is everything less than 0.002 mm. Each of the size fractions is ...
By changing soil properties, plants can modify their growth environment. Although the soil microbiota is known to play a key role in the resulting plant-soil feedbacks, the proximal mechanisms underlying this phenomenon remain unknown. We found that benz
Increase in soil organic-matter content, improved aggregation and water infiltration渗透, a decrease in bulk density容积密度and soil crusting土壤板结following the addition of large amounts of manure to the soil have been reported. The chemical composition of the manure varies, according to the ...
Although macropore volume or macroporosity has been found to be a sensitive indicator, its definition varies. Macroporosity describes the volumetric percentage of pores greater than 30 μm diameter (McLaren and Cameron, 1996). It is primarily soil macropores that are responsible for adequate soil...
