Soil solarization is the third approach for soil disinfestation; the two other main approaches, soil steaming and fumigation; were developed at the end of the 19th century. The idea of solarization was based on observations by extension workers and farmers in the hot Jordan Valley , who noticed the intensive heating of the polyethylene-mulched ...
Cool season weeds are more susceptible to soil solarization than are warm season weeds. [4] Using black plastic as a cover excludes light which can help to control plants that are growing whereas clear plastic has been shown to produce higher soil temperatures. [6]
In solarization, the soil is mulched and covered with a tarp to trap solar radiation and heat the soil to a temperature that kills pests. Biosolarization adds the use of organic amendments or compost to the soil before it is covered with plastic, which speeds up the solarization process by decreasing the soil treatment time through increased ...
With soil solarization, the seed bed is covered with a clear plastic sheet which heats the soil to a temperature that kills pests, pathogens, and weeds. With occultation, black plastic or silage tarps are laid over the soil, creating a moist and warm environment in which weed seeds germinate, and then die due to lack of light.
Since the 19th century soil steam sterilization has been used to clean weeds completely from soil. Several research results confirm the high effectiveness of humid heat against weeds and its seeds. [9] Soil solarization in some circumstances is very effective at eliminating weeds while maintaining grass. Planted grass tends to have a higher ...
A greater diversity of plants in a soil leads to a greater diversity of microbes in the rhizosphere and furthermore can lead to greater suppression of soil diseases. [9] Management, such as informed crop rotation and soil solarization, can create suppressive soils that naturally suppress pathogens. [10]
