Sand-based systems will drain multiple inches of water within a short period of time. This allows a sporting event to be played through a rain or after a short delay. Native soil fields, on the other hand, do not drain well and many games have to be cancelled or postponed due to puddling on the field. The good drainage of a sand-based system ...
The sand equivalent test quantifies the relative abundance of sand versus clay in soil. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 933–8. [1] The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not. A higher sand equivalent value indicates that there ...
The layer depths are determined by the depth of the limiting layer of the soil, which may be a seasonal water table, bedrock, fragrant, or glacial till. Standards created by Ohio State University state that 24 inches of soil should be above the limiting layer in the soil. A 24-inch layer of specifically sized sand is placed on top of the soil.
Drainage is the equilibrium soil-to-geosynthetic system that allows for adequate liquid flow without soil loss, within the plane of the geosynthetic over a service lifetime compatible with the application under consideration. Geopipe highlights this function, and also geonets, geocomposites and very thick geotextiles.
A simplified version of the Emerson soil dispersion test [3] can be completed in the field on a 20-minute to two-hour timescale. Laboratory tests used to diagnose a soil as dispersive focus on the cation exchange capacity of a soil sample and its cation breakdown. Soil cations are dominated by Ca 2+, Mg 2+, K +, and Na +, as well as H + in ...
If the percentages of sand, clay, and silt in the soil sample are known, then the triangle can be used to determine the soil texture classification. For example, if a soil is 70 percent sand and 10 percent clay then the soil is classified as a sandy loam. The same method can be used starting on any side of the soil triangle. If the texture by ...

This is done by adding select clay materials, such as calcium-bentonite, to give the soil more surface area per unit volume and improve soil mineralogy supporting aggregation. A hydrophobic barley field increased crop yield from 1.7 to 3.4 t/ha, and a field of lupins increased the yield by 1 t/ha within 2 years of claying.
