Evaluation of Ammonium Sulfate and Ammonium Nitrate Fertilization on Beef Cattle Stocking Rate, Animal Performance and Bahiagrass Forage Production and Quality
Twelve 10-acre areas will be utilized to test the hypothesis ammonium sulfate fertilization will
support a 10% increase in beef cattle stocking rate. Fertilization treatments will consist of no
fertilizer, ammonium nitrate and ammonium sulfate.
The stocking rate for the 10-acre areas receiving no fertilizer will be a pregnant cow (n = 2)
per 5 acres. Stocking rate for the 10-acre areas receiving ammonium nitrate will be a pregnant
cow (n = 3) per 3 acres. Stocking rate for 10-acre areas receiving the ammonium sulfate will
be a pregnant cow (n = 4) pair per 2.5 acre. This is a 30% increase in stocking rate.
