SNitrogen-36 pounds of nitrogen is equivalent to the nitrogen in 180 pounds of sulfate of ammonia per acre.
The nitrogen was applied annually, the other minerals are total amounts applied during 4 years.
 Phosphorus-144 pounds phosphoric acid is equivalent to the phospho us in 800 pounds of 18% superphosphate.
 Potash-50 pounds is equivalent to 100 pounds of 50% muriate of potash.
2 Leon and Plummer fine said in Alachua County; Bladen fine sand in Duval County; and Fellowship fine sand in Hernando County.
