Soil treatment types can be classified as:
- Organic amendments ( compost, crop residue, animal dung, and sewage sludge among others).
- pH adjusters (such as gypsum and aglime among others).
- Soil protection (pest and weed control).

Seed treatments are the biological, physical and chemical agents and techniques applied to seed to provide protection and improve the establishment of healthy crops. Optimizing production begins with elite genetics and protecting plants from pests and disease.
What is soil treatment for termite?
Pre-construction anti-termite treatment is attracting attention throughout the world. The soil in immediate contact with the foundation and floor structure of a building is treated with an insecticide which kills or repels termites thus forming a toxic barrier which is lethal to termite entry.

A soil profile is a vertical section of soil like the diagram above. It allows you to examine the structure of soil. A soil profile is divided into layers called horizons. The main soil horizons are A, B, C and D. Most important for plant growth, the A and B horizons are the top two layers of the soil.
What is soil treatment?
Soil treatment enables control of the location and the application rate of the inoculant, protects inoculants from the harmful impact of pesticides and fungicides and avoids damage to the seed coats.
Why is soil bad for fungi?
Soil helps to moderate large fluctuations in ambient temperature , which often favours fungal growth and infectivity. One significant potential negative aspect of treating soil with fungi is the occurrence of antagonistic fungi, bacteria and fungal-feeding arthropods and microorganisms.
How to treat fungal spores?
Given the conditions under which fungi thrive, soil treatment of fungal spores is probably the most reasonable application strategy, though it is only suitable if the target insect has a susceptible soil phase. In general, natural soil moisture levels are sufficient to promote conidial germination and mycelial growth, allowing fungal inoculum to be sustained over time. Many agricultural settings irrigate their crops regularly, ensuring that suitable moisture conditions for fungal growth are maintained. Due to concerns about the potential for spores to be leached out of potting medium during watering, Kim et al. (2010c) investigated the downward movement of B. bassiana in potting medium with different levels of moisture and top-watering. They found that the concentration of B. bassiana was greatest in the upper 3 cm of the potting medium, and no significant movement of the spores occurred after 18 days of regular watering.
What is in situ remediation?
In situ remediation refers to a soil-treatment regime in which the soil remains confined to its original location throughout the remediation process. Some earth-moving activities may be required in order to ensure complete exposure of the soil to the remedial treatment.
Does soil moisture help with germination?
In general, natural soil moisture levels are sufficient to promote conidial germination and mycelial growth, allowing fungal inoculum to be sustained over time. Many agricultural settings irrigate their crops regularly, ensuring that suitable moisture conditions for fungal growth are maintained.
What is the best way to treat clay soil?
Soil Treatment for Clay Soil. Soil treatment is essential when trying to break up hard ground, clay and other dense soils. Amending soil is an important component in achieving a successful garden, beautiful lawn and agricultural productivity in clay soil.
Why do people use fertilizers?
Many people have tried fertilizers and other chemicals to help promote health and growth of their plants without getting any improvement in their results. Because of the tendency for runoff with hard clay soil, fertilizer pollution can increase in areas with clay soils.
How does claymend work?
It works to restructure the soil to a more granular texture, which will allow water and air movement throughout making nutrients more accessible. Over time the soil becomes softer and easier to till.

What is the process of removing contaminants from soil and water?
Bioremediation. Bioremediation is the use of biological processes to degrade, transform, or essentially remove contaminants from soil and water. This process relies on micro-organisms including bacteria and/or fungi, which use the contaminant as a food source.
What is the purpose of soil stabilization?
Soil stabilisation involves the addition of immobilizing agents to reduce a contaminants’ leachability. Physical methods, like soil washing, use water to separate or remove contaminants.
What is bioremediation?
Bioremediation is the use of biological processes to degrade, transform, or essentially remove contaminants from soil and water. This process relies on micro-organisms including bacteria and/or fungi, which use the contaminant as a food source. For this reason, bioremediation is widely used to remediate organic contaminants and can be an effective means of mitigating: 1 hydrocarbons 2 halogenated organic solvents 3 halogenated organic compounds 4 non-chlorinated pesticides and herbicides 5 nitrogen compounds 6 metals (lead, mercury, chromium) 7 radionuclides
How does soil washing work?
Soil washing eliminates hazardous contaminants by washing the soil with a liquid wash solution. During this process, fine grained soils, such as silts and clays, are washed away along with contaminants, which are more prone to bind to fine soils. Thus, contaminated fines are separated from cleaned coarse grained soils, such as sands and gravels, which can be safely re-used. Soil washing does not destroy or remove the contaminants and therefore the contaminated soil must be disposed of in a licensed facility.
How can humans be exposed to soil?
People and animals can be exposed to soil contaminants in several ways: by ingesting soil; by breathing violates and dust; by absorbing contaminants through the skin; or by eating food grown in contaminated soil.
How does stabilization reduce the risk of contamination?
It can be achieved in two ways: firstly, by modifying the contaminant in the ground to a less dangerous form; secondly, through solidification, by reducing the mobility of the contaminant and binding it in place so it can’t reach any receptors.
How long does it take to dispose of halogenated organic solvents?
non-chlorinated pesticides and herbicides. nitrogen compounds. metals (lead, mercury, chromium) radionuclides. Often, bioremediation presents a more economic option to disposal, however it can take anything from one to several months to carry out.
In winter, your garden can still be working, creating rich beds for spring planting. From compost to cover crops, here are some soil treatment ideas

What is Soil Treatment?
Soil treatment remediates or fixes soil by adding nutrients and organisms to make it more viable for plants to live. It can also rid soil of harmful chemicals, or amend it if it’s too acidic or has too much clay, sand or rocks.
Soil Treatment Methods
To keep your soil healthy over winter, don’t till it or break it up. That’s better left for early spring. Doing so before the winter disrupts healthy soil structure and biodiversity.

Which Soil Treatment Is Best for Winter?
Whichever ones you can get around to implementing before the snow flies. The more you do, the more your garden will flourish come spring and summer.
When To Apply Soil Treatments?
Most of these treatments are best to do before your soil freezes. Sow seeds of cover crops and add compost so it has time to start the breakdown period. You can mulch anytime, but the earlier the better, as it keeps soil warmer and protected longer. That encourages soil microbes, worms and other organisms to stay awake later.
How to treat wood for termites?
Some of the methods for a termite treatment on wood include pressure-treatment. Pressure-treating the wood and the soil around it makes your structures to be termite and carpenter ants resistant. The treatment involves the application of a chemical preservative through the use of high pressure.

Use Termidor SC to pre-treat the concrete slabs, and this would work better if you apply the insecticide under the selected concrete slab – this is before pouring. But for a slab that’s already installed – you’ll have to inject the chemical termite killer via a drill hole.
Can you use Termidor SC on foundation walls?
For this, you’ll need to use a termiticide such as Termidor SC to pre-treat the foundation walls at their soil level for termites. But pre-treat the soil before pouring the slab – for new construction.
