• Compost Beginnings

    Leaves, grass, and vegetable scraps can be broken down and reused over and over. These organic materials are brought into the composting facility to be decomposed by active microorganisms, forming the rich soil-like material that we love: compost.

  • Mesophilic Phase

    Meeting its task, mesophilic microorganisms rapidly break down the easily degradable compounds while generating a good amount of heat in the process; completing the first step in making top grade compost.

  • Aeration

    Aerobic composting consumes large amounts of oxygen. One of our 'compost kings' will rotate the large rows of compost at the proper time to maintain at least a 5% oxygen concentration to keep the microorganisms active and happy.

  • Thermophilic Phase

    The tough work happens now. Thermophilic microorganisms produce high temperatures as they breakdown major structural parts of plants like woody stems and bark. Measurements of these temperatures are recorded to ensure the highest compost quality.

  • Curing

    The curing period allows the materials to continue to break down until the last of the raw materials are consumed. From here the material is almost ready to use. At this stage, it has the ability to hold more water than basic lifeless dirt.

  • Screening

    Screening and finishing of the product is the last step before you can get your hands on our rich compost. A compost king takes great care in screening the material. We like to be sure that you aren't being sold rocks, debris, or rough pieces of unfinished material.

  • Black Gold

    It's known as “black gold” for a reason. Your lawns and gardens will be nourished for years by compost's ability to add diverse life to the soil. Plant-friendly bacteria, fungi, and worms support long term healthy plant growth and increase the water holding capability of your soil.

DIY Compost and Regulations

Composting is a pretty simple process… right? I can hear you say to yourself, “Composting is easy, all I have to do is toss my organic material in a pile and wait.” That statement, as true as it is, can lead to many issues down the road. Composting is a little more complex than a person many think, but can be very simple if you know what you are doing.

Composting starts with your basic organic material (Yard, food, and animal waste). Once you have organic material, there are a few things you need to create the perfect composting environment.


Moisture is a key component for composting. In a well maintained compost pile, moisture content should be around 50%! Moisture is important because it gives micro-organisms and bacteria an environment to live in and reproduce quickly. Moisture also helps hold and maintain heat within the pile of organic material.


The next component is very important to the composting process: heat. Heat does a couple of things to compost. First off, heat kills many soil-borne pathogens and kills off weed seeds. Though the later reason is not as important, it does make gardening a lot easier!  It is not uncommon for a properly maintained compost pile to reach temperatures over 130 Fahrenheit (whoa!). This great amount of heat comes from the bacteria and micro-organisms breaking down the organic material with the proper amount of moisture and oxygen.


The last component needed to compost properly is oxygen. Oxygen does two things in a compost pile. The first is it allows aerobic bacteria and micro-organisms to grow and reproduce. Because an aerobic (with oxygen) bacterium is present you don’t get the odor that is commonly associated with decomposition of organic material as you would with anaerobic (without oxygen) bacteria. The second thing oxygen does is a result of the first. Anaerobic bacteria not only break down organic material with minimal smell, it will also break down organic material in less time. Organic material can go from start to finish in about six months if proper conditions are maintained.

Oxygen can sometimes be a little tricky to maintain in a compost pile. There are two common methods of keeping the compost oxygenated. The first is simply turning the pile and mixing it once or twice a week. The second method is using a manifold and forcing oxygen into the pile with a blower. We use the first.


Now that you know how the composting process works there are a few things to keep in mind. The first is anyone can compost on their own property as long as they keep the amount of material on site under 50 cubic yards. Once a site gets to 50 cubic yards a permit is required by the state Department of Natural Resources, or if you live in Minnesota the Pollution Control Agency.

How to Use Compost

The secret to thriving vegetables and thick green lawns is nutrient rich compost. Compost is an active material with plant healthy-bacteria, nitrogen, phosphorus, potassium, and micro-organisms. You can’t get that by just adding fertilizer!

Listed below are some of the most common uses for compost:

1. Soil Amendment – Add nutrients to your soil rejuvenating it with compost. Amend your soil with compost by loosening the soil 2-4 inches down in a determined area. Next spread about 3-4 inches of compost on top of the loosened soil and mix it well. Using a tiller to assist with the mixing process will help to oxygenate the soil and give you a more even mix. Our customers use this method in any area of their yards and works especially great in flower beds and gardens.

2. Moisture holding mulch – Compost naturally holds more moisture than regular dirt. When using compost like mulch, first it is important to prepare the area by removing all grass and weeds to prevent them from growing up though the mulch. Next spread the compost around the cleared base of trees, plants, and shrubs. Make sure there is about 2-3 inches of compost material spread evenly. Just like regular mulch, compost breaks down over time. Make sure to add to it once or twice a year.

3. Compost Tea – Your gardens and lawns will thrive from the benefit of this caffeine free drink. Instead of caffeine, this tea energizes your soil with plant healthy-bacteria and microbes without adding additional dirt. You can produce compost tea by first filling a five gallon pail about 1/3 full of compost. Second, top off the bucket with water. Once the bucket is full of the water and compost mix, allow the compost too steep for a couple days. After the compost has steeped simply water your plants with the water from the bucket. If you want to keep the compost separate from the water place the compost in a burlap sack.

4. Lawn Top Dressing – Top dressing your lawn can be done by spreading a thin layer of compost on top of your grass. The compost will work its way into the soil as the grass grows. Apply 1-2 inches of compost to your lawn, rake, and water. Continue to rake it throughout the next few days. Raking will help to work the compost in faster. Top dressing your lawn is best done early spring or late fall after the first hard frost. If you top dressed your lawn, you will not have to fertilize much if at all.

To some gardeners, compost is the life blood of gardening. Some feel that compost is a necessary element that should be added to get the most from their yards/gardens. You may be asking yourself, what are the benefits of adding high quality compost to my yard/garden? According to the US Composting Council, here is a list of reasons you should use high quality compost in your yard and garden.




High Quality Compost…

1. Improves soil structure, porosity, and density giving plants a better chance of developing good root systems.

2. Reduces erosion and runoff in heavier soils.

3. Improves the water holding capacity or soil.

4. Supplies a variety of macro/micro nutrients.

5. Helps to control soil-borne plant pathogens.

6. Supplies significant quantities of organic matter.

7. Improves the soils ability to hold nutrients for plants.

8. Improves and stabilizes soil pH.

9. Supplies beneficial microorganisms.

10. Can bind/degrade specific pollutants.

Community Collection

Dont use your leaves like thisWe all want to live in a clean, safe, environmentally-friendly neighborhood, but what to do with all those leaves, brush, lawn clippings, garden trimmings, and other yard waste items?

We canʼt just throw it away–it is illegal to put such yard waste in landfills (at least in Minnesota and Wisconsin).

We mustnʼt just burn it up–smoke from smoldering leaf piles contains very high concentrations of atmospheric pollutants. At the very least, the smoke is annoying to many of our neighbors. Many communities have placed an outright ban on burning such material.

We shouldnʼt just put it in a pile–unless our goal is to save such material for our childrenʼs children! A static, inactive pile of leaves left unattended will stay in its original condition for years and years.
The best solution, of course, is composting! However, nothing is free in life, and even a simple, ecological, process like composting comes with a significant investment in labor, equipment, site preparation, transportation, and management.

The Backyard Composter:

Anyone can set up a backyard compost site. It is a relatively easy and inexpensive proposition–just build a pile of yard waste, stir in some water, and thoroughly mix it up several times a month–a year or so later, voila! Compost! But, do we all really have the time, energy, and know how to do it right?

The Community Compost Pile:

Many local community leaders have suggested initiatives to establish a compost site accessible to residents to both drop off material and pick up some compost. A good idea, perhaps, but once we start to significantly increase the size of the leaf pile we also significantly increase the cost of properly managing that composting operation. In fact, any compost pile greater than fifty cubic yards must comply with the DNRʼs solid waste regulations. So, do we really want to increase our local tax- supported budget with the cost of obtaining permits, site preparation, material collection, regulatory compliance, and management of a composting operation?

Let the Compost Kings take care of your local communityʼs lawn waste needs!

Communities like the Village of Dresser in northwestern Wisconsin have had a very successful working relationship with the site for many years. Residents are happy because they have a place to take their leaves, garden debris, and lawn clipping, village maintenance crew are happy because they donʼt have to add compost management to their already overly extended work list, and administrators are happy because they donʼt have to oversee an additional department and know theyʼre getting the most out of their budget money!

Expanded Math

In order to determine how much compost you will need, the following tools will be required: Tape measure, pen, paper, and a calculator. Once you have the necessary tools follow these two simple steps.

Step 1: Measuring you project area – Area is measured in a couple different ways depending on the shape of the project. Below are three common examples of how to measure different project areas.

Example 1: Square/rectangular project area

20’ length x 20’ width = 400 feet squared

Example 2: Circular project area

3.141 x 10’ Radius2 = 314.1 feet squared

Example 3: Triangular project area

.5 x 5’ Base x 10’ height = 25 feet squared

Step 2: How many cubic yards of compost – Now that you have determined the square footage of your project area you will have to determine how much compost you will need. Take the square footage (Project area square footage from step one) multiply by the depth of compost that you want to apply. After multiplying your square footage and depth of compost, multiply by .0031.

Example: Taking the square footage from step one, example one and applying 2” of compost to the overall area multiplied by .0031the formula will look like this.

400 ft2 x 2” compost depth x .0031 = 2.48 yards^3

This formula tells us, for an area 20’ x 20’ we will need 2.48 cubic yards of compost to give an overall compost depth of 2” over the entire project area.

You may ask yourself why it matters how much compost you put on your project area. The reason you need to be fairly accurate is because too little or too much compost is not good. Too little compost and the project area will not get enough good bacteria and nutrients. Too much and the nutrients will be wasted.

If you still need help determining how much compost that will be needed for your project, please call or email us with your measurements. A Compost King will respond to help you determine your compost needs.
