title: [Changes of nutrients in soil of transgenic Bt crops].
abstract: Pot experiment showed that after 30 days of transgenic Bt rice planting and by the end of the growth season of transgenic Bt cotton, the contents of soil total C, total N, alkali-hydrolyzable N, and available P and S had no significant difference with the control, which suggested that there was a little disturbance in the cycle and balance of soil nutrients after a short period of transgenic Bt crops planting.
