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 Soil Testing California should be visited.
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.
Finding out the properties of soils is important in order to determine stabilization procedures. Some tests are really simple. Examples of simple tests are smell, shine, color appearance, thread rolling, and hand moulding tests. Smell test usually involves applying water to a sample and if it emits a musty odor, it means that it contains organic materials. Organic materials are usually good for agricultural purposes, but soils that contain it are unsuitable for block making.
Color appearance is also an important test. If the sample contains dark crumbly humus, it means that it contains organic matter. In case the sample contains light brown to black coloring, it means that it can be stabilized even though it contains organic matter to a small proportion. Reddish to dark brown color means that the sample contains iron oxide. Presence of sand and lime-based compounds is indicated by a yellow color. Color appearance test does not however work in all cases.
Shine test on the other hand is performed by rubbing a sample of soil with the back of the finger nail. This is usually done to identify the constituent elements that dominate in the sample. If it is determined that the sample is rough to the touch, it is an indication that sand and silt exist in large quantities in the sample. Samples that contain clay normally have a smooth feel 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.
On the contrary, if the sample breaks before reaching 3 mm in diameter, then it means that it has some amount of sand. The plastic limit of the sample can also be determined using this method. Hand moulding test is done to determine the mouldability and adhesion of the sample in question.
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.
