Compost Formula:

Mushroom Compost is a complicated material made from several different materials. Most of it is made from a base of straw or hay. To that is added a small amount of supplements, minerals and manure. A brief out line on how mushroom compost is made follows...

Phase 1, Agaricus bisporus Compost Formula. 1 - Three wire bale formula.

Day - Treatment to material and ingredients to add.

1 - Monday - Wet down.*Wheat Straw one bale, or Stable straw with 10% horse manure, ( 50 pounds.)

2 - Tuesday - Let it sit:

3 - Wednesday - Let it sit:

4 - Thursday - Add - dried poultry waste and Urea. (1 Pound - Dried Poultry Waste & 1.2 ounze Urea.)

5 - Friday - Let it sit:

6 - Saturday - Flip pile and wet down.*

7 - Sunday - Let it sit:

8 - Monday - Flip pile and wet down.*

9 - Tuesday - Let it sit:

10 - Wednesday - Let it sit:

11 - Thursday - Add - dried poultry waste and Urea. (1 Pound - Dried Poultry Waste & 1.2 ounze Urea.)

12 - Friday - Flip pile.

13 - Saturday - Flip pile and wet down.* - Add 2 pounds - Cotton Seed Hulls.

14 - Sunday - Let it sit:

15 - Monday - Flip pile and wet down.* (Compost will naturally start to heat up to high temperatures.)

16 - Tuesday - Let it sit:

17 - Wednesday - Add - 3lbs. Cotton Seed Meal, 2 lbs. Gypsum, 1 lbs. Rape Seed Meal, 1 lbs. Peat Moss.

18 - Thursday - Turn pile, water lightly.* (Keep the pile in a more compact format to allow heat to build up.)

19 - Friday - Let it sit:

20 - Saturday - Turn pile, water lightly.*

21 - Sunday - Let it sit:

22 - Monday - Turn pile, water lightly.*

23 - Tuesday - Let it sit:

24 - Wednesday - Turn pile, and fill containers. - Ready to pasturize at 142 degrees F. for 6 hours.



First stabilize at 132 F. for 3 hrs. , then raise to 142 F. for 6 hrs.

Finished compost has 65-70% water content.

Slowly let cool for 2 days. Slow clean air ventilation required.

Well made compost is blackish and has a light carmel type coating covering the straw. Over composting will lower mushroom yeilds.

Compost is pasturized to kill any existing undesirable fungi growing in the compost. It can then be innoculated with mushroom spawn.



* Wet down just enough to moisten the material and not enough to cause water run off. Run off washes away the added nuitrients.

Note: Compost should be made on a solid surface (concrete, asphalt, plastic, wood) to prevent the washing away of added nutrients.

The above formula was downsized from a larger volume formula. This smaller volume formula may require additional composting time.
