Soil solarization works by trapping radiant energy from the sun under a thin plastic tarp to heat the soil at temperatures high enough to kill soil organisms. beneficial soil microorganisms that promote plant growth. Summary: Solarization is a simple and safe method to kill weed seeds, nematodes and soilborne diseases prior to planting flower and vegetable crops. caused by certain plant pathogenic fungi and nematodes, or complexes of these pathogens, their land every three to four years, alternating which plots of land will 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. For While the solarization process requires little work and a lot of reward, it can be a daunting task like most garden chores. spend the summer underneath plastic each season. Optimum soil temperature for root growth is 26-28C. Process of Soil Formation SBS is a 67combination of soil solarization, where moist soil is covered with a transparent tarp to 68increase the soil temperature via passive solar heating (Katan et al., 1976), and 69anaerobic soil disinfestation (ASD) where soil is amended with organic matter prior to 70tarping to promote anaerobic microbial activity (Lamers et al., 2010). Soil degradation is the decline in soil quality caused by its improper use, usually for agricultural, pastoral, industrial or urban purposes. However, some growers may want to use a plastic treated with a UV inhibitor so the plastic doesnt breakdown too soon. Microbial communities can be altered due to solarization (Gelsomino and Cacco, 2006), but we do not expect soil microbe populations to be irreparably harmed. All Rights Reserved. heating is sufficient in the top 12 inches of soil to be effective against a wide 1. 70% saturated at least two feet below the surface. As an example, determinate tomatoes in high tunnels in southern Indiana may be grown from the third week of March through July. 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. Once six to eight weeks have passed, remove the plastic, water the soil, work in some compost or organic matter and decide what you want to grow in your newly improved and solarized garden bed. formed and the film and drip tape are applied simultaneously (Figure 2). Location: Sth Florida. Cover the area with clear plastic (such as 1 to 4 mil painter's plastic). There could be potential to reduce the time to 2-4 weeks given the warmer conditions in a high tunnels. Place the edges of the plastic sheeting into the trench you dug and It was created to try and mitigate really extreme situations; tenacious perennial weeds like quackgrass and tough soil diseases like verticillium and fusarium wilt. Water the soil deeply until it is wet. along the top. If it is, then you are ready to lay the plastic sheeting down over the soil. Pathogen and disease control are attributed to microbial, chemical, and physical processes in addition to the thermal killing. as clear plastic, which allows sunlight to pass through more easily, more Additionally, soil solarization improves soil chemistry (enhancing fertility) and provides quite a decent protection from soil erosion. To solarize your soil: 1. Soak it so much that it becomes completely wet and a bit soaking. When soil moisture is adequate, the heat produced pasteurizes the soil, killing 4. At present, there are no recommendations about type or brand of clear plastic to use. UF/IFAS researcher Bob McSorley demonstrates soil solarization. Historically, soil fumigation was used to control soilborne diseases, insect pests Shady areas should be avoided because A second flush of tomatoes may occur in August, but by this time the price of tomatoes may make the continued production of tomatoes into August impractical. Additionally there is chance for greater heating of the soil if the high tunnel vents are all closed which is another advantage compared to the solarizing in an open field. Organic matter increases in the soil when leaves fall and decay into it. The process usually takes four to six weeks and is performed during the hottest period of the year (Katan et al., 1976).
