Mr. Cooper planted 750 acres of cotton. He made three trips over the field to prepare it for planting. He averaged 20 acres per tractor-hour per trip using 0.75 gallon of fuel per acre per trip at $3.18 per gallon. He treated the soil with 2 pints of an herbicide per acre at $98.92 per 2.5-gallon container. Mr. Cooper applied 225-85-155 units of fertilizer per acre using 46-0-0 urea at $509.73 per ton, 18-46-0 DAP at $708.75 per ton, and 0-0-60 muriate of potash at $571.43 per ton. He planted 58,000 seeds per acre with a germination of 88 percent. He had a yield of 2.1 bales per acre. He used a module builder 32 feet long, 7.5 feet wide, and 8 feet high with capacity of 12 bales. At the gin, his cotton was 33 percent fiber (lint).
