Summary of 2012 N Plotsin a Drought Year

• No Difference in Pre vs. Sidedress.• No Difference in NH3 vs. 28%.• No Difference in N Serve.• Boron worked very well in both plots.• Inconsistant performance for RX but saved N.• OptRx performed better in heavy soils.• It appears that 160 lb. rate worked best.
