e1“Fourteen years after no applications of broadcast CSP or KCI fertilizers, responses of sweet corn plants to levels of residual P were greater than to residual K in the soil”
e2“Increasing the level of residual P in the soil increased dry weight per seedling from 1.5 to 7.7 g, fresh weight per ear from 278 to 358 g, the concentration of P from 2.9 to 4.6 mg·g −1 dry weight, but decreased K, Ca, and Zn in the leaves”
