Comment:
Fertilized the LTER Main Site Treatment T5 fertilizer microplots (all replications: 1, 2, 3, 4, 5, and 6) located as the north 50 feet of the T5 main plots. Only the microplots corresponding to treatments N4 (50 lbs N/acre, annual applications starting in 2011), and N5 (100 lbs N/acre, annual applications starting in 2011) were fertilized. Fertilized 6 rows of trees in each microplot (going down 5 alleys between 6 trees) with Ammonium Sulfate (21-0-0-24) . For the 50 lbs N/A microplots, the fertilizer was applied in a single pass (going down the 5 alleys) with the spreader applying 2.7 lbs of AMS. For the 100 lbs N/A microplots, the fertilizer was applied in two passes (down and back each of the 5 alleys) with the spreader applying a total of 5.4 lbs of AMS. Weather conditions around application time was mostly sunny, 79 degrees F and 75 % humidity with calm winds. Green push cart spreader was calibrated and set to 14. All microplots were 6 rows of trees wide (approximately 47.8'). The five alleys inside the microplots is the area that was fertilized. The push cart spreader would throw the fertilizer to the outer two rows of trees. Terry Tilley mowed down each of the 5 alleys within the 6 rows of trees for each microplot to enable the push cart spreader make it through.
