Quick facts
- Solarization is the process of placing a clear plastic tarp over an area to heat up the soil underneath.
- Occultation uses opaque coverings instead of clear. Occultation takes longer.
- The plastic traps heat and moisture, which encourages seed germination and plant growth.
- By blocking access to water and heating up the soil, the process eventually kills the vegetation underneath.

When should I solarize my soil?
Solarization is most effective during the hot summer months when the soil receives the maximum amount of sunlight, as this will kill weed seeds and soil pathogens deep down in the soil.
What is Solarisation in plants?
Solarization is a chemical-free way of controlling pests such as pathogenic microorganisms (mainly fungi, bacteria, and nematodes), insects, and wild plants in the soil before crops planting (Katan, 1987; McGovern and McSorley, 1997; Gill et al., 2009).
What is soil Solarisation write the procedure of soil Solarisation?
Soil solarization weakens and kills fungi, bacteria, nematodes, and insect and mite pests along with weeds in the soil by mulching the soil and covering it with a tarp, usually with a transparent polyethylene cover to trap solar energy.
What can we do after solarization?
Planting your garden after solarization After removing the plastic, you can sow seeds or plant transplants like normal. To avoid bringing any surviving weed seeds to the surface, stick with shallow plantings and practice no-dig gardening methods.
Should I add compost before solarization?
When you are solarizing open soil, try incorporating compost before solarization. Many studies suggest this can increase pest control. Controlling perennial weeds will likely require far more than two weeks of solarization.
How long does soil solarization last?
The soil surface is covered with clear plastic, which allows sunlight to pass through and heat up the soil to temperatures that are lethal to many of these pests. If effective, solarization can reduce population levels of these pests for 3–4 months, sometimes longer.
Can I solarize soil in winter?
Solarization is sometimes used to destroy weeds, and it could be used to kill certain kinds of lawn, but not over the winter, because the method relies on heat.
Where is soil solarization used?
Soil solarization can be used to reduce soil populations of many species of nematodes. This is particularly useful for organic and home gardeners. However, soil solarization is not always as effective against nematodes as it is against fungal disease and weeds.
Why do we solarize soil?
If weeds, soil-borne diseases and pests are posing a serious problem, learning to solarize your soil surface can help. This all-natural technique utilizes the sun to heat the soil, kill lawn weeds and fight off a variety of different issues, including a pest problem or soil-borne pathogen issue.
How does Solarisation control weeds?
Solarization is the process of covering an area with clear plastic to heat the soil and kill weeds and seeds in the top six inches of soil. If done properly, the use of chemicals to control weeds is not necessary.
What do you use for solarization?
Plastic Tarp Choice In general, transparent or clear plastic is most effective for solarization, as the heating rays from the sun will pass through the sheet and be trapped to heat the soil below.
What is solarization in radiography?
Solarization refers to a phenomenon in physics where a material undergoes a temporary change in color after being subjected to high-energy electromagnetic radiation, such as ultraviolet light or X-rays.
How does Solarisation control weeds?
Solarization is the process of covering an area with clear plastic to heat the soil and kill weeds and seeds in the top six inches of soil. If done properly, the use of chemicals to control weeds is not necessary.
What does the Solarize filter do?
The Solarize filter lets you set a lightness value above which image colors are inverted. Solarize used with a blend mode of Subtract to create a stark contrast between shadows and highlights.
What is solarization in soil?
Soil solarization is a technique that uses the sun's energy to battle pests and diseases in your soil. It's especially effective against nematodes, tiny worms that feed on the roots of plants. With soil solarization, a sheet of plastic is used to cover the soil surface, allowing the soil to reach temperatures that are lethal to many pests and weeds.
How long does solarization last?
When done effectively, soil solarization can reduce pest populations for three to four months, and in some cases even longer.
How long does it take for soil to be solarized?
A sheet of plastic is used to cover the soil surface for six to eight weeks. Clear plastic is used so that sunlight is able to pass through it. The soil warms and the plastic traps the heat allowing the soil to reach temperatures that are lethal to many pests and weeds. When done effectively, soil solarization can reduce pest populations for three to four months, and in some cases even longer.
How long does it take for weeds to go away from a solar system?
If your solarization has been successful, you should see a reduction in weeds and soil pests for the next three to four months —long enough to grow a fall garden! Follow these links more information on soil solarization, or contact your local Extension office.
What is the best soil for solarization?
Moist soil is best for solarization as moisture helps to conduct heat. If possible, apply your plastic the day after a rain or irrigation. Solarization will not work as well on very dry soil or, alternately, very wet soil.
How to prepare a site for solarization?
To prepare your site for solarization, you'll want to clear the area of weeds and debris and incorporate any soil amendments that you plan to add. You can till into the top six inches of soil to help increase heat penetration, although this isn't necessary.
How thick should a plastic sheet be?
The plastic sheet should be a little larger than the area you are treating. It should be at least 1.5 millimeters thick to prevent the plastic from eventually hardening and shattering into thousands of little pieces by the end of the process.
Soil solarization
To avoid negative consequences, many non-chemical methods have been researched and applied to control pests and diseases. One such method is exposing the soil to the sun. Soil solarization is a pest control technology that uses radiant heat from the sun to kill many soil-borne pathogens.
Greenhouse
It is very similar to a greenhouse. Because heat is captured and used, this method causes some physical, chemical, and biological changes in the soil in the most natural way. These changes lead to the control or suppression of soil-borne pathogens and diseases.
Weeds
This technique works best in sunny and high temperature areas. However, recent revisions indicate that it can also work in colder areas and colder times of the year. Pathogens and weeds that are not controlled by the sun have also been detected.
Long term effects
Long-term effects, including biological control and increased growth response, have been verified in various climatic regions and soils, demonstrating the universal applicability of solarization.
Disease control
What is soil solarization? and what is pros and cons Sun exposure to soil cannot completely eradicate soil pathogens and diseases. However, studies have shown that pathogens can re-infect sun-dried soil at a slower rate than untreated soil.
Weed control
What is soil solarization? and what is pros and cons? Sunlight from the ground can control various weeds because many of them are sensitive to soil moisture and high radiation. After a year of treatment, this aspect is usually evident.
Nematode control
In part, sun exposure of the soil can reduce nematode populations. Nematodes are a family of parasitic worms, which includes hookworms and pinworms, and are generally found in soil. Because nematodes are generally heat resistant, sun exposure is most effective and economically feasible for shallow-rooted crops and gardens.
What is solarization in soil?
Soil solarization is a preventive, organic method of killing weeds before weed seeds even sprout. 1 But the advice below is also meant for homeowners wishing to start a garden with a clean slate, reclaiming a patch of land where weeds have taken over, in such a way as to reduce to a minimum the hassle of future weed control.
How to solarize soil in the Northern Hemisphere?
If the raking mentioned above was done diligently enough, there will be no sharp objects sticking up to puncture the plastic. The sheet of clear plastic can be anything from 1 to 6 mil. in thickness. In the Northern hemisphere, the best time for soil solarization is June and July, when the sun is at its peak. UIE recommends keeping the sheet of clear plastic tightly stretched out over the area for about 2 months. During that time, the sun will be killing weeds for you—"cooking" them before they have a chance to sprout. Plant pathogens will be killed, to boot.
How to remove a stump from a tree?
If you are looking for a cheap way, use a tool called a "mattock." Dig and chop your way with the mattock under the root-ball to access and remove the taproot. Warning: this is hard work and may be feasible only for smaller stumps.
How to prepare soil for solarization?
The final preparation for soil solarization will require the use of a garden hose. According to the University of Idaho Extension (UIE), you should moisten the area that you have just raked to "conduct and hold heat, to stimulate weed seed germination, and to prevent dormancy of below-ground vegetative plant parts.".
How to keep plastic from blowing away?
Cover the raked, moistened area with a clear polyethylene sheet. The edges of the sheet can be held down by cinder blocks to keep the plastic from blowing away. If the raking mentioned above was done diligently enough, there will be no sharp objects sticking up to puncture the plastic.
When is the best time to solarize soil?

UIE recommends keeping the sheet of clear plastic tightly stretched out over the area for about 2 months. During that time, the sun will be killing weeds for you—"cooking" them before they have a chance to sprout.
Can mulch be used to kill weeds?
Of course, if you use an organic mulch (such as a bark mulch), it will eventually decompose anyhow, becoming fertile ground for weeds. What can you do? Well, you had better keep new weeds pulled, faithfully. Vigorous roots pushing downwards can stress landscape fabric and breakthrough. On the bright side, these weeds should be relatively easy to pull, since mulch is a lot looser than dirt, and weed roots will not become impossibly entrenched.
Soil Solarization: An Organic Soil Treatment Method
Soil solarization is an organic soil treatment method that helps control pests residing in the soil. The health of the soil is a major concern in crop production. Farmers face huge problems resulting from the poor state of the soil, thus, this leads to reduced yield in crop production.
What is soil solarization?
Soil solarization is the use of sunlight rays to control or eliminate pests: seed weeds, insect eggs, and larvae; residing in the soil. Soil sterilization is the application of heat to the soil to eliminate pest residing in the soil. The two are methods of soil treatment.
What Is Soil Solarization?
The process suggests covering weed-clean earth with a transparent air-proof substance (typically plastic) to accumulate solar energy, which raises soil temperature. The major purpose of soil solarization is to kill weeds and all sorts of pests with the obtained heat. Depending on location, the temperature in the 5-cm (2-inch) topsoil under solarization may range from 108-140°F (42-60°C).
Does Soil Solarization Kill Beneficial Bacteria And Other Microorganisms?
Solarization kills many bacteria and may threaten beneficial biota, too. This is why it is important to restore the balance by adding organic matter after completion.
Why is soil testing important?
Soil testing matters because the soil solarization method is not equally efficient for all types. It works better in soils with good water retention properties (containing clay or loam).
How long does it take to solarize soil?
Typically, the process lasts from four to eight weeks. It should be enough time to conduct soil solarization before planting fall crops. Provided all the requirements are met, the earth treatment spares agronomists the trouble of pests for three to four months.
How long does it take for a pest to die from solarization?
The treatment duration is different, depending on species. While some will die just in several days, only 4-6-week sun exposure will be lethal to others.
What is the best material for heating?
The thinnest polyethylene (1 mil) is the best to get maximum heating, but it is damaged easily, too. In windy areas, 1.5-2 mils polyethylene is typically used. Smaller territories are sometimes covered with thicker plastic (4 mils).
Why is it important to fit plastic to the ground?
It is important to fit the plastic as tight to the ground as possible as air space reduces heating and will cause plastic “waves” on windy days, which will dissipate heat.
What is Solarization?
In very simple terms, solarization means using the heat from the sun to kill the weed in your garden. In this method the gardening area is covered with clear polyethylene then it is exposed to the full hot sun so that the light and heat can reach to the ground and cook the weed seeds which remained hidden inside the soil.
Why is water important in solarization?
Water is a very important element in solarization process. It helps in heat conduction. Avoiding water will not give you your desired result.
