Study on Potential Impacts of Genetically Modified Cultivation on Soil Physical and Chemical Properties
Year: 2012
Type: article
Abstract: With the application and promotion of genetically modified crops, the safe of Bt-transgenic crops on soil had become one of the hot spot. In present study, two parallel experiments were conducted to compare the impacts of transgenic cotton on the rhizosphere soil properties in northern China. The results showed that the pH value increased, except for the cotton 33B. Furthermore, the change extent varied with Bt transgenic cotton and non Bt cotton. In addition, organic total carbon、 total nitrogen and available nitrogen decreased, while these of GK-12 increased. In general, the effect was different from cotton cultivar. Available P and K in the rhizosphere zone increased among all cotton cultivars tested, and no significant difference was found between Bt and non-Bt cotton
