Soil mixing of stratified contaminated sands

Journal of Hazardous Materials, 2000
Validation of soil mixing for the treatment of contaminated ground is needed in a wide range of site conditions to widen the application of the technology and to understand the mechanisms involved. Since very limited work has been carried out in heterogeneous ground conditions, this paper investigates the effectiveness of soil mixing in stratified ...

Enantioselective dissipation of pyriproxyfen in soils and sand

Chirality, 2017
AbstractUnder normal conditions, the environmental behaviors of pesticides are affected by complex environmental factors and the manner of administration together with constraints. In order to meet the actual needs, we imitated the experiment and found that the degradation rate of pyriproxyfen in soils rendered complex changes.

Sand Content of Sand‐Soil‐Peat Mixtures for Turfgrass

Soil Science Society of America Journal, 1979
Abstract Soils subjected to intensive foot‐traffic in areas used for sports usually require modification in order to maintain physical properties conducive to turfgrass growth. Commonly this is achieved by mixing soil with large quantities of sand and often some peat.

Computer aided determination of proportion of sand in a soil

2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015
Determination of soil texture has always been very important for agricultural researches. Since determination of proportions of sand, silt, and clay in a soil by traditional methods requires more effort, in this study, we focus on performing soil analysis by an automated computerized system.

Phosphate Removal by Sands and Soils

Groundwater, 1977
ABSTRACT Phosphate retention by soils is especially important for tile fields and rapid infiltration systems near lakes where eutrophication is a problem. The use and application of the phosphate adsorption isotherm test to estimate a soil's phosphate removal ability will be discussed.

Acoustic Absorption in Sand and Soil

The Journal of the Acoustical Society of America, 1948
The acoustic absorption properties of sand and soil with varying amounts of water, ranging from dry to saturated, have been investigated. In most of the work the frequency range was 10–30 kc, although data were obtained at as high as 150 kc. Two methods were used.
