Comment:
Fertilized the LTER Main Site Treatment T5 fertilizer microplots (all replications: 5, 1, 2, 3, 4, and 6) located as the north 50 feet of the T5 main plots. Only the microplots corresponding to treatments N2 (50 lbs N/acre, single application in 2011), N3 (100 lbs N/acre, single application in 2011), N4 (50 lbs N/acre, annual applications starting in 2011), N5 (100 lbs N/acre, annual applications starting in 2011) were fertilized. Fertilizer was applied as granular CAN27 which is a 27% ammonium nitrate + calcium fertilizer. For the 50 lbs N/acre microplots, the fertilizer was applied in a single pass of the applicator. For the 100 lbs N/acre microplots, the fertilizer was applied in two passes of the applicator. Applied using the JohnDeere 4400 garden tractor and the small Gandy air-seeder. The Gandy was calibrated to apply the equivalent of 8' of width of fertilizer, but into a 6' wide pass. All microplots were 6 rows of trees wide (approximately 47.8'). The five alleys inside the microplots received the full amount of fertilizer. The two outside alleys received only 1/2 rate of the fertilizer and then only on the 1/2 of the width of the alley corresponding to that microplot.
