What is Mushtroom Compost?

Mushroom compost is derived from almost 100% organic ingredients, including composted hay, corn cobs, brewer's grain, and cocoa beans shells or soya bean meal.  These ingredients are combined and encouraged to undergo the composting process, after which the compost, as well as a mixture of peat moss and ground limestone, become the home for mushroom growth.  Once the mushrooms are harvested, the compost becomes an effective soil conditioner, offering minerals and nutrients.

   
Why Choose Mushtroom Compost?

Mushroom compost revitalizes your soil and acts as an excellent soil conditioner for your lawn, garden, and flowerbeds.  The essential nutrients within the soil are slowly broken down by microorganisms, allowing plants to access the nutrients for a longer period of time.  As the microorganisms increase soil activity, heavy clay soils will be broken down, providing improved drainage. This soil activity will also build up sandy soils, providing moisture retention.

Besides being an excellent soil conditioner, mushroom compost will also help divert nature's valuable resources from landfill sites.

   
What is the Composting Process?

1.The essential ingredients are combined to allow the composting process to occur. During this process , the material is broken down with the help of microorganisms, aeration, and the generation of heat.
  Fresh compost is ready to be pasteurized once it has a chocolate brown colour, soft straws, sufficient ammonia (which is the exclusive food source for mushroom growth) and enough moisture.

2. Pasteurization is a necessary step in the process since it kills any insects, pest fungi, nematodes, or other pests that may be in the compost.  The fresh compost is transferred into the "mushroom houses", where it fills the bottom 2/3 of the boxes designed for mushroom growth.  The other layer, approximately 1/3 of the boxes, is made up of a mixture of peat moss and ground limestone, which has also undergone the pasteurization process.

3. After the mushrooms are harvested, the mushroom house is sterilized again, eliminating any contaminants that may be left behind.  The spent mushroom substrate is removed by conveyor belts, allowing the two layers to blend together.

 

4. The spent compost, now called mushroom compost, is sterilized and ready to be sold.

 


If the soil is extremely sandy or filled with clay, spread a 5-6 inch layer of mushroom compost on the top and mix it with 6-8 inches of existing soil.

If the soil is not too bad, spread a 3-4 inch layer of mushroom compost and mix it in with 6-8 inches of existing soil.

The mushroom compost will also provide efficient moisture retention, and offer nutrients to the soil.


If mushroom compost is applied yearly, there may be excessive
amounts of nitrogen, potassium and phosphorus in the soil.

Mushroom compost should be worked into the existing soil due to
its richness and the possibility of being blown away when dry.

You will not find any mushrooms within your mushroom compost.
