Sprayed fertilizer in the GLBRC Main Site Treatment G10, MICROPLOT area only, all replications (replications 1, 2, 3, 5 and 4). Treatment G10 microplots were fertilized with 50 lbs N/A applied as 28% N fertilizer (CAS #57-13-6 Urea, #6484-52-5 Ammonium Nitrate). 28% fertilizer weighs 10.67 lbs / gallon so the 50 lbs N/A worked out to 16.7 gal 28%/A. Each treatment plot was divided into two areas: fertilized microplot areas 15' wide located on the west side of treatment plots [G10R2, G10R3, G10R4, and G10R5] and located on the east side of the treatment plot G10R1; unfertilized areas which were the remaining 76.86' on the east side of the plots [G10R2, G10R3, G10R4, and G10R5] and located on the west side of treatment plot G10R1. The fertilized 15' microplot received 50 lbs N/A. The unfertilized 76.86' was NOT fertilized. Conditions: Cloudy with air temperature 68 degrees F. Relative Humidity was 83%.
