Turf Applications
Fields, lawns, and fairways require three 84 kg.N.ha-1 applications in the growing season. Guidelines for these applications vary depending on the method of application. If applied through a fertigation system, no dilution of Sulfert 8 is required. Likewise, mix nozzles automatically dilute Sulfert 8 and prior dilution is not required. For spray applications, Sulfert 8 must be diluted with water in a ratio of between 1:2 – 1:5 depending on the environmental conditions at the time of application. In general, a 1:3 dilution will mitigate the risk of scorching turf.
Spray Application
- Sulfert 8 liquid fertilizer must be diluted with water in a ratio of between 1:2 – 1:5.
(Refer to table for detailed instruction.)
- E.g. To apply at a rate of 84 kg.N.ha-1, mix 1 litre (1.2kg) of Sulfert 8 with two to five litres of water and apply to 12m2.
- Apply evenly over the appropriate surface using a fertigation system, venturi nozzle, spray applicator, or any other suitable dispersion device. For large areas, a fertigation system is recommended for cost effective and fast application.
- Spray application in gusty wind should be avoided to prevent uneven dispersion. A wind speed of less than 8 km/hr is preferable.
- Irrigate well after application to prevent scorching.

Creating Blends
Sulfert 8 is highly soluble in water. When adding supplementary nutrients, allow mixture to stand overnight to guarantee a well-mixed solution. Verify that the supplementary ingredients are compatible with Sulfert 8 prior to mixing to prevent chemicals precipitating out of solution (e.g. Potassium Nitrate should be avoided).
When to Fertilize
Three applications are generally needed for turf – early spring, late spring, early autumn.
EARLY SPRING
When rapid growth begins.
(Late Aug — Sep*)
LATE SPRING
Prior to summer heat and drought stress
(November*)
EARLY AUTUMN
After summer heat and drought stress.
(Late March*)
