Why do you need to apply sulfur to your lawn?
It should be applied according to soil-test recommendations because excesses may burn your lawn. An undesirable consequence of applying sulfur is the building of soluble salts, which can burn grass roots.
Why do you put sulfur on grass?
When you apply sulfur to your lawn, it works to unlock these inaccessible nutrients from the soil so grass roots can absorb them.
What are the effects of sulfur on grass?
Sulfur's Influence. If grass has a sulfur deficiency, it may show chlorotic symptoms that include yellowing, stunted growth and spindly blades. Sulfur is also a key player in adjusting soil pH. Microorganisms oxidize elemental sulfur and transform it into sulfuric acid, which lowers the soil’s alkalinity and brings its pH toward the acidic range.
What is the pH of a lawn?
Soil pH. Ideally, the soil pH for your lawn should be in the range of 5.5 to 7.0. However, the soil pH of most urban lawns is typically higher -- more alkaline -- than the nearby, native soil. Urban development is largely responsible for this unnatural shift.
What soil types benefit from sulfur?
Sulfur Correction. Typically, the soil types that benefit from sulfur applications are sand, silt and loam. Sulfur is supplied by fertilizers in various forms, including ammonium sulfate, gypsum and ferrous sulfate. The University of Michigan offers guidelines for the amount of sulfur you may need to lower the pH of your soil.
Can sulfur be used to fix lawns?
Sulfur is not an immediate fix; typically, it works slowly in the soil. It should be applied according to soil-test recommendations because excesses may burn your lawn. An undesirable consequence of applying sulfur is the building of soluble salts, which can burn grass roots. Commonly, the salt buildup occurs in lawns with poor drainage. Before attempting to lower the soil pH or correct iron deficiencies with sulfur, correct any drainage problems so water flows freely from your lawn and there are no soggy areas.

Role of Sulfur in Plant Nutrition
Sulfur (S) is considered a secondary macronutrient with an average concentration in most plant tissue of approximately 0.15 percent—the lowest relative concentration of all the macronutrients. Sufficient plant S is important for nitrogen (N) use efficiency, grain quality, and animal nutrition.
Forms and Behavior of Soil Sulfur
The vast majority (70 to 90 percent) of soil S is stored in organic matter. There are also some S-containing minerals (e.g., pyrite) and organic molecules (e.g., amino acids) present at low levels in most soils. The most important plant-available form of S, sulfate (SO 42- ), is an anion.
Predicting Sulfur Needs of Field and Forage Crops
Deficiencies are most likely to occur in coarse-textured soils with low organic matter and that have not received a recent manure application (an important source of S). It is also not uncommon to see S deficiencies early in the season, when soil is cool, roots systems are small, and organic matter mineralization is minimal (Figure 3).
Meeting Crop Sulfur Needs
In situations where S fertilizer additions are likely to be beneficial, recommended application rates are 15–25 lb/A S for grain crops and 25–50 lb/A S for forage crops.
Conclusions
Sulfur is an essential nutrient for plant growth that historically was provided in adequate levels for agricultural production through acid rain deposition. Current levels of atmospheric sulfur deposition have dramatically declined, creating the need to monitor and manage sulfur fertility in crop fields.
Why is fertilizer important for lawns?
Fertilizers are important in lawn care because they supplement the soil with needed nutrients. Nutrients are needed by grass plants because of the many stresses people apply to them. Grass uses nutrients to repair damage done by normal wear and mowing.
