Soil testing is a crucial process in agricultural and lawn development processes. There are various processes that can be employed to test the viability of soils for agricultural purposes. Some of the procedures are so extensive and can only be conducted in laboratories. There are others however that are simple and are done in the field, on-site. When one needs Soil Testing California offers the perfect location to visit.
In case an individual has purposed to put their land on large scale farming activities, more extensive soil assessments should be done. However, in case the aim is small scale farming or lawn development, a simple sample test is sufficient. Soil analysis is normally done to ascertain the various elements found in soils like silt/clay and sand fractions. These tests also measure malleability of the soils.
To determine stabilization procedures, it is also vital to know the exact properties of the soils in the area. Some of the simple tests include shine, smell, thread rolling, hand moulding, and color appearance tests. In smell test, water is normally applied to the sample and if it produces a musty odor, it is an indication that it has organic materials. Normally, organic materials are good for agricultural activities. However, soils with organic materials are not good for block making.
Also, another vital test is color appearance. This test indicates that the soil has organic matter if the sample used comprises of dark crumbly humus. Samples that contain brown to black coloring can be stabilized although a small amount of organic matter is contained in it. The presence of a dark brown to reddish color implies that the sample has iron oxide. A yellow color means there is lime-based compounds and sand in the soil. The working of color appearance test is limited to a few cases only.
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.
When it comes to thread rolling test, sufficient water is added to the sample in order to be easily molded by hand. This sample is rolled out using the palm of the hand on a clean surface. In case the sample can be rolled to a diameter of about 3 mm, it is an indication that the sample contains 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 mentioned tests are normally preliminary and can be conducted on-site in the field. In case more extensive testing is needed, samples should be taken to a laboratory for additional tests to be done. To determine different elements and properties, different tests are done for each.
