If wetting soil beforehand, place plastic covers over the site as soon as possible after the water has been applied to reduce evaporation. Pest Notes: Weed Management in Landscapes, Soil Solarization: A Nonpesticidal Method for Controlling, Diseases, Nematodes, and Weeds. Multiple beds can be covered by a single sheet of plastic, but heating may be reduced and the plastic may sail when it is windy. The effect of solarization is greatest at the surface of the soil and decreases at deeper soil depths.

The technique is unlikely to be helpful against late blight (which is air-borne), but may be effective against early blight (which is soil-borne) if done correctly.

Stapleton JJ, Dahlquist-Willard RM, Achmon Y, Marshall MN, VanderGheynst JS, Simmons CW. To answer your first question, it is suggested to solarize your soil for a minimum of 4 weeks, as long as the soil temperatures reach 108-131 degrees. The method involves heating the soil by covering it with clear plastic for four to six weeks during a hot period of the year and when the soil will receive the most direct sunlight. It has also been used successfully in the cooler coastal areas of California during periods of high temperature and no fog. Statewide IPM Program, Agriculture and Natural Resources, University of California You can also do a fall cover crop that will winter kill and provide organic biomass and natural mulch. Thin plastic provides greater heating, but is also more susceptible to tearing from wind or animals walking on it (1 mil). While you may be able to find success with winter solarization in warmer areas, those in cooler climates likely wont be able to take advantage of solarization until spring or even early summer. French Leaving the plastic in place more than 8 weeks could be. -

Nondiscrimination Statement. The goal is to maintain daily maximum temperatures in the top 6 inches of soil at or above 110 to 125F. I dont think it will take much to reach these temps in peak summer, especially if your garden is mostly in direct sun. Conversely, during very hot weather, pests may be controlled with a shorter period of solarization. The process is simple enough: So what are the benefits? 2016.

Soil Solarization in Southern European Countries, with Emphasis on Soilborne Disease Control of Protected Crops (Angelo Garibaldi and M. Ludovica Gullino). Control of soil pests is usually best for organisms found in the upper 6 inches of earth. Plants often grow faster, with higher and better-quality yields, when grown following soil solarization. I had some problem with blight the past few years. While some weed species seeds or plant parts are very sensitive to solarization, others are moderately resistant and require optimum conditions for control; that is, good soil moisture, tight-fitting plastic tarps, and high solar radiation. 
After solarization, the plastic may be removed, taking care not to disturb the underlying soil to avoid bringing up viable weed seeds from untreated edges and furrows or from deep layers that did not reach lethal temperatures.

The degree to which various pests can be controlled is related to the intensity, depth, and duration of the elevated soil temperatures, as well as to the sensitivity to treatment of each pest species. Highest soil temperatures occur when days are long, air temperatures are high, skies are clear, and wind is minimal. Bulgarian See our Home page, or in the U.S., contact your local Cooperative Extension office for assistance. For instance, most soilborne pests will be controlled after only 4 weeks of solarization during June through September in Californias Central Valley and desert regions. It is suitable for solarizers, researchers working with soil-borne pathogens and soil microbiology, plant protection experts, and other plant researchers and extension specialists.

Czech Stapleton JJ. 
Soil within most regions of California, except high elevation areas and some coastal valleys, can be reliably solarized if treatment is instituted during the period of late June through August. The sun heats the soil to temperatures that kill bacteria, fungi, insects, nematodes, mites, weeds, and weed seeds.. In cool, windy, or cloudy locations, or if there are pests present that are difficult to control, it may be necessary to leave plastic in place up to 8 weeks. 0000048565 00000 n

Romanian l staked down the plastic and checked the soil temperature under the plastic on a regular basis. Like I mentioned before, mulching will also help build the soil and keep weeds more under control. When properly done, the top layers of soil will heat up to as high as 140F, depending on the geographic location. 
The double layer of plastic can increase soil temperatures by up to 50F, and placing containers on pallets allows for heating from all sides of the soil mass. German (Switzerland), Spain In this case, the black plastic should be left in place for several weeks during the hottest part of the year. The process involves covering the ground with a tarp [] to trap solar energy. 2018. 0000017619 00000 n
Four to six weeks of soil heating during the warmest time of the year is usually sufficient to control most soil pests. If the soil will be cultivated prior to planting, the cultivation should be shallow (less than 2 inches deep) to avoid bringing viable weed seeds and pathogens to the surface. If a longer solarization period is desired, small areas can be covered again with fresh plastic.

ANR ASSOCIATE EDITOR: AM Sutherland - Unless the soil gets dry during the course of soil solarization, or you are aiming to do an ASD treatment, do not irrigate again, as this will lower the soil temperature and lengthen the time required for successful solarization. Slovak Granberry). Solarization seems to have long-term success in controlling weeds. Soil Solarization explores the effects of soil solarization, covering such points as biological control, changes in soil chemistry involving mineral elements, as well as other changes, such as soil salinity and soil structure. As long as youre aware of the drawbacks, it could make your future gardening endeavors much more successful. July is the most reliable time to solarize, except for coastal areas, where persistent, warm, fog-free periods may not occur until August or September. The maximum temperature of soil solarized in the field is usually from 108 to 140F at a depth of 2 inches and from 90 to 99F at 18 inches. Unfortunately, we cannot provide individual solutions to specific pest problems. Soil solarization improves soil quality as the heat helps break down organic material into nutrients more readily absorbed by plants, according to the. Alternately, treated soil may be detoxified via irrigation, leaching organic acids and other toxins below the root zone. Air pockets between the plastic and the soil can greatly reduce soil heating and promote sailing of the plastic in the wind. 0000003816 00000 n
