Prepared By Bill Copeland
My Personal Predictions for Plots Before Harvest
• Preplant would out perform Sidedress• nH3 would out perform 28%.• N Serve would make no difference.• Boron would make no difference.• No Idea what to expect on N RX.• OptRx would not works as well.• Higher Rates of N would produce more corn.

How the Plot Data Will Be Presented• Summary of Plot Will Be Shown First.• Followed by a chart showing deeper analysis.a) Layout of Plotsb) Consistency of Performance
