Soil solarization is a technical system to control soil-borne pathogens and pests under the soil without using chemicals. This systemwas developed in 1979 [1]. It is an easy technique which can
be used for both small and huge plantation areas, with low expenses and no pollution to the environment. In addition, it helps the crops grow faster and yield better quality produce. A polyethylene plastic sheet is used to cover the soil to increase the heat accumulated under the plastic sheet to its highest possible degree. The soil used in the solarization process must be wet or moist; therefore, water has to be dropped down into the soil to increase moisture when the soil moisture is less than 50% [2]. A plastic sheet is needed to cover the soil continuously for 4–6 weeks in order to enforce the accumulated heat to the deeper levels of the soil. This
process will increase the soil temperature higher enough to destroy or to inhibit soil-borne plant pathogens, weed seeds and seedlings, nematodes, and soil residing mites. In addition, there are several factors concerning the heat which is transferred down to the different depths of soil: the length of heat receiving time, heat flux, environment temperature, soil moisture, thermal conductivity levels, and soil capacity degree of maintaining water [3]. Furthermore,
this process also increases the essential minerals for plants [2].
