Sulfur, which is required for chlorophyll formation, is one of the nutrients that plants require to flourish. The availability of these nutrients in the soil is determined by soil properties and climate. Sulfur levels in sandy soil in the western United States are typically lower than in sulfur-rich loam soil in the Midwest and Eastern United States.
Why Your Lawn Needs Sulfur
Turf grass requires a variety of macronutrients and micronutrients to survive, including nitrogen, potassium, phosphorus, and sulfur. Sulfur, for example, is essential for chlorophyll formation, and a lack of it can cause plants to turn yellow. Nutrient availability is determined by soil features and climate, with sandy soils in the western United States often having lower sulfur levels than loam soils in the Midwest and Eastern United States.
How to Tell If Your Lawn Needs Sulfur
Before applying sulfur-rich fertilizer, conduct a soil test if you suspect a sulfur deficiency. Soil tests can help determine whether nutrients are missing and discover other probable causes of poor growth. Soil test kits, which contain a summary of nutrient levels and suggested remedies for nutrient shortages, are available from a local Cooperative Extension Service or commercial soil testing services.
How to Apply Lawn Sulfur
You can find complete lawn fertilizers in the form of granules that are simple to spread. Spread them with a walk-behind fertilizer spreader, calibrated to the recommended rate as specified on the fertilizer package instructions. Apply the fertilizer on a calm day and walk at a consistent pace to ensure an even spread.
FAQs
When should I fertilize my lawn with sulfur?
Only use sulfur if a soil test shows a deficiency. Most soils have enough sulfur to support healthy lawn growth.
Can sulfur reduce soil pH, and how much should I use?
It would take several years of consistent sulfur application to even marginally reduce the pH of soil. Sulfur does not work well for lowering soil pH. A balanced lawn fertilizer is preferable.
How fast will sulfur turn my lawn green?
After applying a sulfate fertilizer to a sulfur-deficient lawn, it will become green within one to three days. When applying any fertilizer, always follow the recommendations on the product label for the best results.
