Solarization affects all living organisms that are present in the upper 30 cm (11.8 in) of the soil. It can be used to manage weeds, diseases caused by soil-borne pathogens, and nematodes. Effectiveness of solarization can be somewhat variable when methyl bromide is the standard with which it is compared.
Light colored surfaces reflect a large amount of solar radiation.On the surface of the ground, solar radiation is reflectedback into the atmosphere. In a confined space, such as a solar box cooker, solar radiation can be reflectedagainst other surfaces, as shown below. This type of heat transfer is called radiation.Solar radiation reflected and absorbed Heat is mainly transferred through conduction and convection.owever, heat can also be lost via conduction through the bottom of the cooker. To reduce this, a plate with spacers can be added to the bottom of the box. Conduction Radiation While most of the radiation in a solar cooker comes from the sun, the interior of the box, pots, and bottom plates, also radiate heat.
