摘要: Despite the recent interest in organic agriculture, little research has been carried out this area. Thus, objective of study was to compare, a dystrophic Ultisol, effects and conventional agricultures on soil organism populations, for tomato (Lycopersicum esculentum) corn (Zea mays) crops. In general, it found that fungus, bacterium actinomycet populations counted by number colonies media, were similar two cropping systems. CO2 evolution during season higher, up double agriculture system as compared conventional. The earthworms about ten times higher system. There no difference decomposition rate matter microartropods always plots relation ones, reflectining Shannon index diversity. insect population belonged Collembola order, case mites, superfamily Oribatuloidea. Individuals groups Aranae, Chilopoda, Dyplopoda, Pauropoda, Protura Symphyla occasionally collected both
