Organic compounds extracted with ethanol (OCEWE) from soybean rhizospheic soil on continuous and alternate cropping at pod-string were identified by gas chromatography-mass spectrometry (GC-MS). The results showed the compounds mainly include organic acids, alcohol, acetone, aldehyde, naphthalene phenyl and furan hydrocarbon, many of which were reported as allelochemcals. Under this experiment condition, OCEWE did not show any allelopathy on soybean seed germination and radicle growth, which might be related with their critical toxicity concentrations. In addition, the relationship between allelopathy and barrier on soybean continuous and alternate cropping was also discussed.
