That was my first thought Denny but the results surprised everyone. This year for example near Batavia NY which was on the droughty side we ended up with 14 ton from the planted plot at 37,000 ppa and 13.4 ton from the broadcast plot at 29,000 ppa. This picture tells another story. Tonnage is one thing nutrient value is another.
The 6 cobs on the left of the tailgate were plucked from 6 plants in the planter plot. The 10 cobs on the right side of the tailgate came from 6 plants in the broadcast plot.
The tool we used to broadcast was this one shown below
It is hard to switch from one system to another and this is the kind of thing where you dont do it without trying it first. The cool point is that you don't need anything fancy... you just have to keep your head about you because we have all been doing this long enough to know when we have a good seed bed and when we dont.
