For Good Soil Testing California Offers A Recommendable Destination
by Kimberly Campbell
Soil testing is a very important procedure for agricultural and lawn-making processes. There are several different processes that can be used to test the suitability of soil for agricultural processes. Some of these methods are very comprehensive and can only be conducted in a laboratory setting. Others however, are very simple and can be conducted on-site. When in need of <a href="https://www.advancedgeotechnical.com/about/">Soil Testing California</a> should be visited.
One must use more comprehensive techniques of assessing soils if they want to utilize the land for large scale agriculture. However, if the intention is to use the land for installing a lawn, simple tests should be sufficient. In this case, determining the soil components like clay/silt and sand fractions is normally the reason for conducting the tests. Also, the tests can assess for mouldability.
Assessing soil properties is vital so as to determine the procedures needed to stabilize it. There are tests that are quite simple to conduct such as shine, color, appearance, smell, hand molding and thread rolling tests. Smell tests normally work by adding water to samples and if the smell emitted is musty, it means that the soil has organic matter. Presence of organic matter is normally good for agriculture, but such soils may not do well with block making.
The color appearance test is equally important. A sample containing dark like matter is an indication of the presence of organic matter. When the sample has light brown to black hue, it implies that even though it has some organic matter, it can be stabilized. Soils that contain iron oxide are normally reddish or dark brown in color. Yellow color in a sample is an indication of lime-based elements. However, the color appearance test does not always work in all cases.
Shine test is conducted by rubbing a small sample of the soils with the back of a finger nail. This is done to identify what components dominate in the sample. If the surface of the soil is abrasive to the touch, then it means that sand and silt exist in great amounts. If the sample contains clay, it will be smooth to the touch.
Sufficient volume of water is added to a sample in thread rolling test. This is done in order to make the sample easy to mould by hand. One then rolls out the sample with the palm on a flat and clean surface. In the sample can be rolled to a diameter of 3 mm without breaking, it means that it has a lot of clay in it.
In the event that the sample breaks before it can be rolled to 3 mm, it implies that there is a lot of sand in it. Also, the elasticity limit of the sample can be tested using thread rolling. Properties that can be tested for using hand moulding include malleability and stickiness of a sample.
All the tests mentioned above are preliminary and can be done in the field, on-site. In the event that more complex testing is needed, one must take the sample to the laboratory for further assessment. Different tests that are intended to determine different properties and components exist too.
