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.
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.
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 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.
