Other claims from this paper (6)
- Observation Bt protein concentration in the rhizosphere of corn variety 34B24 fluctuated between 46.593 and 76.943 ng dry soil g(-1) through the season.
- Observation Bt protein concentration in the rhizosphere of corn variety 1246×1482 increased steadily from 21.63 to 62.53 ng dry soil g(-1) through the season.
- Intervention effect Total and available N/P/K in soil did not differ significantly between Bt and non-Bt corn soils.
- Observation Sucrase, protease and acid phosphatase activities differed significantly at only one sampling time and for two treatments that did not correspond to Bt versus non-Bt.
- Observation Dehydrogenase and urease activity and soil respiration differed significantly among several corn treatments at most sampling times.
- Association Soil respiration of corn cultivars 34B24 and 34B23 was higher than that of the other cultivar set throughout the growing season.
