Fertilized Soybeans Increase Corn Yield

In a recent 6 year study conducted at the Agronology 10 Research Center in Walcott, IA, dribble banded soybeans increased corn yields by 8.4 Bu/A vs. the non-fertilized soybeans.  When a 17-40-80-10s was fall, dribbled for soybeans on a very high testing P&K soil, corn yields were increased on average from 207.4 Bu/a to 215.8 Bu/A for the 6 year period.  The average soil test value on this very high testing soil was a P1 of 35 ppm and Exchangeable K of 239.
