Ammonium Thiosulfate, 12-0-0, 26% Sulfur

Product Downloads pdf

Ammonium Thiosulfate is an excellent source of ammoniacal nitrogen that is quickly absorbed by the plant. This results in greener turf, even at low soil temperatures. Use when a liquid type of ammoniacal nitrogen source and sulfur are required.

Ammonium Thiosulfate is a neutral to slightly basic (7 - 8 pH), clear liquid solution, containing 12% nitrogen and 26% sulfur. Ammonium Thiosulfate is compatible with most liquid fertilizer materials. Nitrogen and sulfur are important components of proteins. Sulfur deficiency can affect the plant’s ability to utilize nitrogen for protein synthesis.

Directions For Use:

Greens, Tees and Fine Turf: Apply 3.0 - 12.0 oz. of Ammonium Thiosulfate with 1.5 -2 gallons of water per 1,000 sq. ft. (1.0 - 4.1 gallons of Ammonium Thiosulfate with 66 - 88 gallons of water per Acre) every 14 days throughout the growing season. Irrigate after application. This application shall provide 0.03 - 0.12 lb. of actual Nitrogen per 1,000 sq. ft.

Fairways, Roughs, Sports Turf and Lawns: Apply 3.1 - 4.1 gallons of Ammonium Thiosulfate with 44 - 88 gallons of water per Acre (9.0 - 12.0 oz. of Ammonium Thiosulfate with 1 - 2 gallons of water per 1,000 sq. ft.) every 14 days throughout the growing season. This application shall provide 0.09 - 0.12 lb. of actual nitrogen per 1,000 sq. ft.

Fertigation: Apply 1.0 - 5.0 gallons per Acre (3 - 15 oz. per 1,000 sq. ft.) of Ammonium Thiosulfate with the irrigation water. Repeat as needed every 7 - 14 days during active growth period.

Application Precautions: Do not apply Ammonium Thiosulfate directly on or below germinating seeds such as in a “pop up” fertilizer. Dry soil conditions and/or combination with other starter fertilizers may damage germination. Always irrigate with sufficient water to reduce the possibility of fertilizer injury. Avoid application during mid day when temperatures are high.

Ammonium Thiosulfate should not be mixed with acids or other acidic materials below a pH of 6.
