What Are Micronutrients for Turf Grass?

Still, they are vital to a healthy, inviting lawn. The easiest way to feed your turf grass micronutrients is to leave your grass clippings on your lawn so they can decompose back into the soil.

The eight essential turf grass micronutrients are:

• Iron (Fe)
• Manganese (Mn)
• Zinc (Zn)
• Copper (Cu)
• Chlorine (Cl)
• Molybdenum (Mo)
• Boron (B)
• Nickel (Ni)

Soils with a high pH experience micronutrient deficiencies more often. Iron is typically the first and most deficient element. Along the Southern and Western coastal areas of the United States, iron and manganese are frequently deficient. Sometimes, even if iron is present in the soil, it may not be available for turf grass to use.

Iron—along with the macronutrient nitrogen—is typically used to enhance the greenness of turf grass. Applying to your lawn’s leaves (i.e., foliar application) produces a rapid color response, whereas granular applications will improve your lawn’s green hues over time. Unfortunately, if your soil already contains enough iron, additional granular applications will not have any effect on color
