Suggested Method for Performing the Borehole Shear Test
ASTM Committee D18.02 on Sampling and Related Field Testing for Soil Investigation (Mr. Ralph Brown, Chairman) suggested that this proposed suggested method be published herein to provide exposure and solicit comments for users. The purpose is to improve its clarity, accuracy, and acceptibility, so that in the future, Committee D18.02 may submit it for publication in the Annual Book of ASTM ...

Portable soil sensors can monitor soil parameters
Summary: Compared with the traditional agricultural planting in the past. In modern agricultural planting, people often use a variety of advanced instruments and equipment to detect the various conditions of soil information. And the appearance of portable soil sensor, so that people can detect the content of various substances in the soil anytime and anywhere. So as to meet the high demand for ...

Response of corn and cotton to starter phosphorus on soils testing very high in phosphorus
Phosphorus from agricultural lands poses a problem in water resources. In 2003, more than 48% of soil samples submitted to the North Carolina Department of Agriculture and Consumer Services (NCDA&CS) soil testing laboratory tested very high in soil P (>120 mg dm–3 P). As soil test P increases, off-site P loss increases, through erosion, soluble P runoff, or leaching. On soils testing above high ...

New Field Test for Lead (Pb2+) in Soil
Field tests for the detection of lead in soil are not frequently accepted, since the tests are rather cumbersome or not reliable for screening determinations. Recently, we developed the LEADQuick field test kit for the detection of lead in water with 3 g/L sensitivity. This test is further modifiedto detect lead in soil with a sensitivity 0.03 g. We developed an extraction protocol using ...

The Vane Cone: A New Device for Soil Shear Strength Measurement
A considerable number of in-situ tests have been devised for measuring field soil shear strength parameters. These tests include, among many others, cone penetration and vane shear devices. The conventional form of each of these two devices controls the type of soil deformation, which may limit the use of the measured soil shear resistance data. In this study both vane and cone devices were ...

Field Hydraulic Conductivity Tests for Compacted Soil Liners
Field hydraulic conductivity tests are required to determine the in situ hydraulic conductivity of compacted clay soils used in the liners for hazardous waste management facilities. The test must be capable of measuring hydraulic conductivities of 1 × 10-9 m/s or less, and the values obtained must be representative of the overall soil liner. Few of the methods available are capable of both ...

The potentiation of zinc toxicity by soil moisture in a boreal forest ecosystem
Northern boreal forests often experience forest dieback as a result of metal ore mining and smelting. The common solution is to lime the soil which increases pH, reducing metal toxicity and encouraging recovery. However, in certain situations, such as Flin Flon, Manitoba, Canada, liming has only yielded moderate benefits with some locations responding well to liming and other locations, not at ...

Edible Oil Barriers for Treatment of Perchlorate Contaminated Groundwater
An EOS® biobarrier was designed and implemented to remediate perchlorate contaminated groundwater. The report describes the site characterization, design steps, implementation, monitoring results and lessons learned from this effective remedial approach. EXECUTIVE SUMMARYThis final technical report documents the demonstration of emulsified edible oils for remediation of perchlorate in ...
