How to Do a Wash Test to Determine the Value of Your Soil

A soil wash test will tell you a great deal about your soil and its value. The nutritional value of your garden soil is difficult to determine by visual inspection alone.

When you guess what is in your soil without testing first you usually guess wrong. The only true way to be sure about your soil's value is to make a wash test. Light sandy soils are the easiest to test. They generally contain little clay. Heavier soils with higher clay content are harder to test because of the strong electrical attraction developed by the acid clay particles for lime. There are some alkaline clay soils, but most are acid. The bond between the clay and lime in the soil can be broken by adding two tablespoons of ordinary nitrate of soda fertilizer to the test.

To do a wash test to determine the value of your soil; take a clean, clear half gallon size container and fill it halfway up with water. Add a half a cup of your garden soil to the jar. Screw the lid on tightly and swirl the water around in the container rapidly for approximately one minute. Let everything settle and repeat this process several times. Afterwards allow the container to stand until the water clears. Clay particles are very fine and may take up to a week to settle.

When the water has cleared and settled, the various sized particles contained within in the soil will settle in layers according to their density. On the very top will be the clay particles and on the bottom you will see sand, fine gravel, and other larger bits of mineral. Between each layer will be silt. Organic matter will make up less than 5 percent of the volume of most soils. No mixture of clay, sand, and silt can be called real soil unless it contains some organic matter.

The organic mater will not be very conspicuous in the wash test results because at best, it makes up less the 5% of the volume of most soils. However, it is extremely important to the overall mix of the soil because of the two crucial rules it plays in the plants development. First it acts as an absorbent, allowing the plants to soak in the nitrogen, phosphorus, potash, and other nutrients. Second it provides a home for the billions of microorganism that exist in the soil.

Soil is alive. In order for your garden to thrive it is important to add and maintain its organic matter as they are vital to the proper feeding of the plants. Adding fertilizer alone is not sufficient. Actually adding fertilizer to soil that is missing organic matter is a waste. One of the best ways to add organic matter to soil is the addition of a healthy compost mixture.The water test separates the soils components, allowing you to determine its make up. Once you are aware of the ratio of clay, sand, gravel, minerals, and silt in your soil, you can determine what you need to do to make the soil suitable for the gardening purpose you intend. Adding fertilizer to the soil is one way to improve the value of your soil. Adding top soil is another alternative that will add benefit to the soil and make it more adaptable. However, the addition of organic matter will elevate the soils value and enhance its properties far better than either of these two methods.
