Abstract

There is shown a mushroom casing mix having a core material of up to 100% sphagnum peat moss and a concentration mix of wollastonite and dolomitic limestone in a ratio of 10:85 per 1 yard of core material. After adding the concentration mix to the core material, the mushroom casing mix is configured to have an enhanced ability to maintain a pH between 7.5 and 8.2 within 14 days after the concentration mix is added to the core material.

Claims (19)

1. A mushroom casing mix comprising:

a core material consisting of up to 100% sphagnum peat moss;

a concentration mix comprising wollastonite and dolomitic limestone in a ratio of 10:8.5 per 1 yard of core material; and

wherein the mushroom casing mix is configured to maintain a pH between 7.5 and 8.2 within 14 days after the concentration mix has being added to the core material.

2. The mushroom casing mix of claim 1 , wherein the enhanced ability of the mushroom casing mix to maintain the pH range between 7.5 and 8.2 extends within 14 days after the concentration mix is added to at least 60 days after the concentration mix is added.

3. A mushroom casing mix comprising:

a core material consisting of up to 100% sphagnum peat moss;

a concentration mix comprising of wollastonite and dolomitic limestone, wherein when the moisture content of the core material is about 54.4% the concentration of wollastonite in the mushroom casing mix is about 3.82% by weight and the concentration of dolomitic limestone in the mushroom casing mix is about 3.25% by weight; and

wherein the mushroom casing mix is configured to maintain a pH between 7.5 and 8.2 within 14 days after the concentration mix has being added to the core material.

4. The mushroom casing mix of claim 2 , wherein the enhanced ability of the mushroom casing mix to maintain the pH range between 7.5 and 8.2 extends from within 14 days after the concentration mix is added to at least 60 days after the concentration mix is added.

5. A method of reaching a pH range between 7.5-8.2 in a mushroom casing mix, comprising:

providing a core material of up to 100% sphagnum peat moss;

adding a concentration mix of wollastonite and dolomitic limestone; and

configuring the ratio of the wollastonite and dolomitic limestone at a ratio of 10:8.5 per 1 yard of core material to provide the mushroom casing mix with an enhanced ability to maintain a pH between 7.4 and 8.2 for a period of time after the concentration mix is added to the core material, and wherein the period of time is within 14 days to about at least 60 days.

6. A method of reaching a pH range between 7.5-8.2 in a mushroom casing mix, comprising:

providing a core material of up to 100% sphagnum peat moss;

adding a concentration mix of wollastonite and dolomitic limestone; and

wherein the core material is adjusted to have a moisture content of about 54.4%, and at this moisture content, the concentration of wollastonite in the mushroom casing mix is 3.82% by weight and the concentration of dolomitic limestone in the mushroom casing mix is about 3.25% by weight; and

wherein the mushroom casing mix is capable of maintaining a pH between 7.4 and 8.2 for a period of time after the concentration mix is added to the core material, and wherein the period of time is between 14 days to about at least 60 days.
