When soil is no longer fertile, decontamination is a great way to revive it. Finding out what exactly is contamination the soil is the first step in fixing the problem. There are a few steps that you can follow to figure out what agents are contaminating your soil.
Soil that has a 50 ppm or greater or VOC concentration is considered contaminated. VOC which stands for Volatile Organic Compounds, can make growing anything dangerous or impossible. Getting rid of these compounds is possible. It can also help to restore the soil to its fertilizer state.
Generally, decontamination soil involves using an organic solvent to cleanse the soil. The solvent dissolves the explosives or other harmful materials. The materials that are volatile will become weakened and vulnerable to natural bacteria. The bacteria will work to break the chemicals down and return the soil to a fertile state.
An organic nutrient composition is also generally added to the soil to help ease decomposition. This process happens directly in the soil. This is good because it means that you do not have to worry about removing any of the soil to get it back to normal. Once it is treated, the bacteria just needs time to do its job. Once completed, the soil will become usable again.
Thermal soil remediation is a process that destroys the petroleum distillates and other oil-based substances. This may be the thing that you need to get your soil back to normal. This will require local or state professionals to come in and treat your soil with extreme heat.
You can also try to use mild solvents to get the contaminates out of the soil. By gathering soil and agitating it you can see if it separates the soil from the contaminating agents. This is a simple and less expensive means to solve soil issues. Iron remediation takes the contaminated soil and removals pesticides or herbicides from it. A certain amount of iron is used to wash the soil. The chemicals that are in the soil are broken down. Next the soil is removed and replaced in the affected area. A sheet of plastic is put over the soil to help turn it back into fertilizer, useable soil.
To soak up contaminates, you can plant genetically altered cottonwood of poplar trees. They work to absorb mercury from the soil and release it back into the air. Another method of decontamination is to spread a large tarpaulin over the soil that needs to be decontaminated. Wet the ground and allow it to sit for a number of months before you check it again. If you are dealing with a small area that needs to be decontaminated, you can follow a few smaller steps. Take activated charcoal and spread it around the contaminated area. This will work to immediately decontaminate the soil and return it to a fertile state.
If the contamination is bad, you will need to contact the local county soil decontamination professionals. They will be able to assist you with genetically altered tress and cleaning supplies. If you are determined to solve the problem yourself you will need to get rid of the contaminated soil in a proper manner. Find out what the state and local codes are concerned contaminated soil.
Contaminated soil is not something you want to take lightly. It is very important to make sure that you do not grow plants and flowers in soil that is not good. Of course, many times, contaminated soil will yield no growth. Be sure that you are growing your garden in healthy soil.
