Abstract
This research is included in the project "Research of possible causes of sterility in rice panicle”. In a few studies, conducted to determine the etiology of infertility, was reported as possible cause of disease the wrong degradation of the organic matter with consequent production of toxic molecules. The purpose of this thesis was to study the evolution of organic matter in correlation to the different agricultural management that are frequently used in a Italian rice field. The study was conducted in an area that has been divided into four sections through the combination of straw management and water management water. In the soil were placed electrodes for the measurement of temperature, pH, potential Red-Ox. The experiment lasted three years, in every season were carried out five soil sampling at various stages of rise crop. Each sample was investigated chemical and biological parameters. The results obtained indicate that, contrary to as reported in the literature, even in the highly reducing condition, the organic matter is decomposed [...]
