For the average lawn with 10,000 to 12,000 square feet, about 150 pounds of mixed fertilizer is required. Make the last nitrogen application prior to August 30 in north Arkansas, September 15 in central Arkansas and September 30 in south Arkansas. If soil test does not call for complete fertilizer, apply 3 pounds of ammonium sulfate instead. Do not apply more than 2 pounds of actual nitrogen per 1,000 square feet per year. Back To Top Cool-Season Grasses Apply 5 to 10 pounds of mixed fertilizer per 1,000 square feet in early fall.
Most lawn grasses are quite tolerant of soil acidity.
When the soil pH drops below 6.0, lime is needed. It is urgently needed if the pH drops to near 5.0. A soil test is strongly advisable as a basis for applying lime. However, if you know your soil is strongly acid, apply about 50 pounds of ground limestone or 40 pounds of hydrated lime per 1,000 square feet. Test your soil before liming again.
