Comment:
Fertilized GLBRC Main Site treatments G2 (5, 3, 2, 1, and 4) sorghum plots. Knifed in 30 gallons/A of 28% liquid fertilizer. 28% fertilizer weighs 10.67 lbs per gallon so this equals about 90 lbs of actual N/A per pass. Knifed on 30 inch centers 6-8 inches deep, in two passes for the 15 inch rows. Both passes mistakenly made at 30 Gallons/A of 28%, meaning each plot was fertilized with 160 lbs of actual Nitrogen. The no Nitrogen Micro-plots were also mistakenly fertilized at the same rate as the rest of the plot.
