The term “soil contamination” gives us an understanding of clean. But there is no definition for clean soil. Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotics chemicals or other alterations in the natural soil environment. We all want clean energy, clean rooms, and clean soil.
What Is Soil Contamination?
Soil contamination occurs when hazardous chemicals are buried or spilled or have migrated into uncontaminated soil. Contamination can take place during improper disposal of hazardous chemicals, during the application of pesticides and fertilizers, or through chemical and industrial processes. Additionally, these substances may be deposited if contaminated water washes through an area or if particles from industrial smokestacks fall from the air and combine with the soil. Materials such as lead, cadmium, arsenic, and fertilizers are several possible ones for urban soil.
Good Topsoil Can Help Define Clean Soil
A good quality topsoil will have a good balance of sand, silt, and clay in order for plant life to obtain the required nutrients to thrive. Topsoil is pretty important – after all, without it, you wouldn’t have any plants! Soil is the foundation of your garden and once you understand it and get to grips with it, you can begin to improve it in time. Topsoil needs to be nutrient and mineral-rich.
Soil pH – What it Means
The pH scale goes from 0 to 14 with pH 7 as the neutral point. As the amount of hydrogen ions in the soil increases the soil pH decreases thus becoming more acidic. From pH 7 to 0 the soil is increasingly more acidic and from pH 7 to 14 the soil is increasingly more alkaline or basic. It is important to know what the soil level is. Clean soil typically falls between 6-8 on the pH scale. If soil is on either side of the 6-8 range it is considered contaminated.
Usually soil companies can give you several blends of soil, such as topsoil, lawn soil, garden soil, and a compost/soil blend. Some will even allow you to custom-make your mix, such as 40 percent compost with 60 percent topsoil. Creating quality soil requires time, labor, and expensive equipment. The cost of soil varies by location, quality, and quantity.
