Solarization is a hydrothermal process which brings about thermal and other physical, chemical, and biological changes the moist soil during, and even after, mulching. Organic matter, the soil is the most important component, emerges as an important parameter in the solarization applications, because it contains many changes and events. The experimental site was located at the University of Suleyman Demirel Research Center in Isparta. Greenhouse experiments were conducted during 2011-2012 in the 60 day period (July-August). The experiments were arranged as a randomized block design, with three replications per treatment, based on a plot size of 2m x 2m. Four soil treatments and control (non-sol) were applied: solarization, biofumigation, bubble solarization and bubble-water solarization. After the experiment, samples of treated soil were taken from 15 and 30 cm depths from the center of each tested plot, immediately after termination of solarization and then soil was tested organic matter. The high organic matter content is determined in Sol treatment according to data from the year 2011. According to these results, it can be said that Sol treatment was the lowest mineralization in applications. Similarly to the first year, in 2012, while amount of organic matter decreased with depth, it was determined that only an increase in BSol treatment. Based on these results, it was concluded that soil organic matter with solarization application convert available nutrition form to plants with decomposition it.
