Milorganite Vs. Ringer Fertilizer (Here’s the Difference)

Milorganite Fertilizer vs. Ringer Safer Fertilizer

Are you looking for a safe organic fertilizer that you can use for all your fertilizing needs, including lawns, trees, shrub, flowers, and vegetables? Milorganite and Ringer are both excellent organic fertilizers.

If you have never used a fertilizer before, it can be confusing at first. Use the wrong fertilizer or too much, and you will burn your plants. Both Milorganite and Ringer fertilizers can be used for all your fertilizing needs.

They are safe, won’t burn your plants, and are recommended for beginners to use. Read on to find out how they compare so that you can make the best choice for you.

What’s In Fertilizer

What the Numbers Mean

On a bag of fertilizer, there are numbers, for example, 6-4-0. The first number is nitrogen content. The second is the phosphorus content, and the last digit is the potassium content. Each of these elements is needed for healthy lawns and plants.

Nitrogen stimulates green color, growth and keeps diseases, like dollar spot form taking hold.  When analyzing the nitrogen contents, you want ¾ nitrogen per pound.

Phosphorus promotes root development and is needed for starter fertilizer. A fertilizer with phosphorus is an excellent choice for fall fertilizing. However, some areas restrict the use of phosphorus in fertilizers. Be sure to check your local laws.

Potassium is an all-around element that is used to strengthen lawn and plants. If you prefer the green-blue look for your lawn, be sure to look for iron in the micro-nutrient section on the bag.

Fertilizer Math

Comparing the Cost of Fertilizers

It is necessary to figure the cost to get the best nutrient cover per pound of fertilizer. To make this easy, we will discuss how to do the math for a 1000 sq. foot lawn.

For gardens, and plants remember your square footage is very small; therefore, you will need less. Don’t panic, with both Milogranite and Ringer will not burn your plants if you accidentally apply too much.

Step One: Calculate The Square Footage of Your Lawn

Take the length of the lawn and multiply it by the width. If you have an odd-shaped yard, break it up into sections, do the math, and add all your totals together. Length times width= square footage.

For a circular lawn, use the formula 3.14 (pi) x the radius (from the center to the edge) squared.  Wouldn’t your Geometry teacher be happy?

Step Two: Determine Nitrogen Analysis

This step takes a little bit of Algebra, but don’t worry; we have done the math for you. Divide 75 by the amount of nitrogen in the fertilizer mix (the first number listed on the bag). Why 75? Because you want 75% nitrogen per pound.

  • Milogranite Divide 75/6 = 12.5 lbs. per 1000 sq. feet
  • Ringer Divide 75/10 = 7.5 lbs. per 1000 sq. feet

If your lawn is larger or smaller, you will need to adjust the total. For example: for a 4000 sq. foot yard, you multiply by 4. Suppose the yard is 500 sq. feet, you divide by 2.

Step Three: Calculate the Cost to Get Good Nitrogen Coverage

To figure the cost per pound, take the total amount of pounds in the bag and divide it by the price of the bag.

  • Milogranite 32 pounds/$20.00 = $1.60 cost per pound
  • Ringer 36 pounds/$36 = $1.00 cost per pound

Next, take the cost per pound and multiply it by pounds needed for good Nitrogen coverage figured in step two above. Remember, the numbers we have are for a 1,000 square ft yard.

  • Milogranite $1.60 (price per pound) x 12.5 (amound of nitrogren needed) = $20.00 cost of nitrogren coverage
  • Ringer $1.00 (price per pound) x 7.5 (amound of nitrogren needed) = $7.50 cost of nitrogren coverage

Ringer has won the cost analysis, but that is not the only test we used to compare Milogranite vs. Ringer. Keep reading to find out more.

Are Milogranite and Ringer Safe?

Ringer is made up strictly of plant parts. It is all organic and safe for pets and children. You do not need to worry about it burning your lawn or plants if you apply too much.

Milogranite is a biosolid made from the sludge out of the Milwaukee, Wisconsin sewer systems. Microbes digest the nutrients in the water, and the clean water is returned to Lake Michigan. The microbes are kiln-dried to make fertilizer pellets.

According to their website:

  • Milogranite uses Extensive testing for quality control.
  • Meets all federal and state requirements.
  • Pathogens are killed by extreme heat.
  • Safe for Children and pets
  • It will not burn your plants if you apply too much.

What do Ringer and Milogranite Smell Like?

Ringer is all plant-based and has a sweet smell. Similar to yeast or a brewery on brewing day.

Milogranite does not smell too bad when dry. However, they have a stout aroma when wet.

Ease of Application

In this test, we looked for which fertilizer would give a heavier coat and was easier to see.

The Milogranite pellets are smaller. They flew further, getting between the blades of grass and down to the soil. The downfall is it can be hard to tell exactly where the coverage has already been laid.

The Ringer pellets are larger and did not fly as far, resulting in a smaller coverage with each pass. They got hung up on the tops of the blades of grass, requiring watering to work them down to the soil.

Which Shows Results Faster?

Results will depend on heat, water, and friction. The Milogranite consistently showed results in 10 to 12 days. The Ringer showed much faster results in 4 to 5 days.
