Soil micro nutrients for lawns are the elements that your grass needs besides the basic staples of nitrogen, phosphorus and potassium. That is why your soil test results come with a lawn soil micro nutrient level section.
There are many micro nutrients for lawns in the soil but we’ll concentrate on the items listed on our soil test results.
Those would include:
- Baron (B)
- Manganese (Mn)
- Zinc (Zn)
- Copper (Cu)
- Iron (Fe)
Refer to the soil test results example – Click Here. You can see the soil micro nutrients are measured in PPM parts per million. Directly to the right of that number is the desired range required by soil. While Manganese is bit low the remaining nutrients are in range though on the lower side. Iron being the only exception.

Benefits and Functions of Soil Micro Nutrients for Lawns
Portions of the following information was obtained from (Brady & Weil, 1999)
- Baron (B) Activates certain enzymes. Essential for cell division and development. Needed for root growth
- Manganese (Mn) Activates a number of essential enzymes. Important in photosynthesis and nitrogen metabolism. Deficiencies include slow growth
- Zinc (Zn) Present in a number of enzymes. Promotes the formation of growth hormones and starch, promotes seed development. Promotes seed development. Deficiencies include yellowing.
- Copper (Cu) Present in several enzymes. Important in photosynthesis, protein and carbohydrate metabolism, and probably nitrogen fixation. Deficiencies include grass blade being limp.
- Iron (Fe) Present in several important enzymes. Important in chlorophyll formation.
Usually having good organic matter percentage, correct soil pH and an acceptable CEC level will result in these micro nutrients for lawns being in acceptable range enabling success with organic lawn care.
If the nutrient levels aren’t where they should be we’ll change that when we add healthy tested compost.
Many people do not take account for soil micro nutrients for lawns. Plant life is obviously complex and all contributing factors are important.
