2. Soil test - Wikipedia

   en.wikipedia.org/wiki/Soil_test

   A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.

3. Standard penetration test - Wikipedia

   en.wikipedia.org/wiki/Standard_penetration_test

   The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide. The test procedure is described in ISO 22476-3, ASTM D1586 [1] and Australian Standards AS ...

4. Cone penetration test - Wikipedia

   en.wikipedia.org/wiki/Cone_penetration_test

   CPT and CPTU testing equipment generally advances the cone using hydraulic rams mounted on either a heavily ballasted vehicle or using screwed-in anchors as a counter-force. One advantage of CPT over the Standard Penetration Test (SPT) is a more continuous profile of soil parameters, with data recorded at intervals typically of 20 cm but as ...

   Unseasonably warm temperatures have many Ashland County residents itching to get their hands in the dirt and get to work on their gardens and flower beds.

6. Base-cation saturation ratio - Wikipedia

   en.wikipedia.org/wiki/Base-cation_saturation_ratio

   Base-cation saturation ratio (BCSR) is a method of interpreting soil test results that is widely used in sustainable agriculture, supported by the National Sustainable Agriculture Information Service (ATTRA) [1] and claimed to be successfully in use on over a million acres (4,000 km 2) of farmland worldwide.

   To collect soil samples, gather soil from 10 to 12 spots in a yard or garden. For lawns, dig three inches deep; for gardens, at least eight inches. Combine the samples in a container, break apart ...

8. Oedometer test - Wikipedia

   en.wikipedia.org/wiki/Oedometer_test

   An oedometer is fundamentally made out of three components: a "consolidation cell" to hold the soil sample, a mechanism to apply a known pressure over the sample, and an instrument to measure the changes in the sample's thickness. [12] The equipment required to perform an oedometer test is sometimes called an "oedometer test set".

9. Soil science - Wikipedia

   en.wikipedia.org/wiki/Soil_science

   A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
