摘要

Common wisdom that soybeans don't respond to fertilizer is dead wrong. So is the widespread perception that potas-sium fertility is likely more limiting than phosphorus.That's according to Fred Below, a University of Illinois plant physiologist. Recent research he conducted with graduate students to break the100-bushel soybean yield barrier suggests both notions are in error."It's a myth that soybeans don't respond to fertilizer," says Below, who adds that "wisdom" may be a carryover from research on soybean nitrogen fertility, which shows inconsistent response to extra N.
