Clay mineralSoilThe effect of clay mineral composition on Cs adsorption behavior of silt and clay fractions (SC-fractions) of soil was investigated. Surface soil samples were collected within 2 km of Kori and Wolsong nuclear power plants in South Korea, and SC-fractions (<20 渭m) were ...
Soil TextureNatural RadionuclidesIn this research, a gamma ray sensor (The Mole) was used to get the natural radionuclides concentration in in the surface layer of cultivated soils. For sand, silt and clay predictions, an adaptive neuro fuzzy inference system (ANFIS) was performed to predict ...
Sands have small surface areas and have an almost negligible role in the chemical activity of the soil, i.e. they are chemically insert or inactive. Sand acts as the framework for the active particles, i.e.: silts (fine) and clay. Sand does not hold much water because the particles ...
Ammonium acetate lactate-extractable K (K-AL) was rapidly depleted, and in K0 the K-AL level stabilized at 30 and 100 mg K kg -1 in the silt and clay soil, respectively. Corrected for different ''minimum'' values, the K-AL value predicted the K uptake by ryegrass from AL extractable...
When studying carbon (C) sequestration in soil, it is necessary to recognize the maximal storage potential and the main influencing factors, including the climate, land use, and soil properties. Here, we hypothesized that the silt and clay contents in so
4.For example, the strength of the cement soils from loam and silt are 1.45～4.5 times as large as the soil from clay.亚粘土和粉土的水泥土强度分别为粘土水泥土的1.45～4.50倍; 5.On long-distance subsurface excavated construction in twin-track tunnels of silt and silty fine sand stratum粉土粉...
Silt and clay not only protect microbial carbon from decomposition but also enhance its production in dryland soils.Silt and clay relieved environmental stress on microbes by increasing soil water content and pore spaces.Microbial processing interacts with plant inputs to control the contribution of MAO...
3) silty clay loam 沉泥质黏壤土4) recently deposited muddy soil 新近沉积淤泥质土 1. In this paper a series of seismic settlement tests of recently deposited muddy soil in Nanjing city were performed by WFI dynamic cyclic triaxial apparatus made in England. 本文通过英国WFI振动三轴仪对...
Without a microscope, sand, silt, and clay soil particle sizes are impossible to measure directly so sediment testers determine the coarse fractions by separating the size grades with precision sieves and weighing them. For the smaller particles, they use tests based on how fast the different size...
