Abstract

A mushroom spawn-supplement comprising a mixture of: (a) at least one proteinaceous ingredient in an amount to provide at least 3.5% nitrogen on a dry weight basis; (b) 2 to 30 wt % based on dry weight of paper pellets (c) 5 to 60 wt % based on dry weight of at least one particulate material, (d) a buffer in an amount effective to provide a pH of about 6 to 7.8, and (e) water; and colonized with Agaricus bisporus mycelium.

Claims

1. A mushroom spawn-supplement comprising a mixture of:

(a) at least one proteinaceous ingredient in an amount to provide in the mushroom spawn-supplement at least 3.5% nitrogen on a dry weight basis;

(b) 2 to 30 wt % based on dry weight of paper pellets;

(c) 5 to 60 wt % based on dry weight of at least one particulate material;

(d) a buffer in an amount effective to provide a pH of about 6 to 7.8; and

(e) water; and

colonized with Agaricus bisporus mycelium wherein the (b) paper pellets, (c) particulate material, or both are present in an amount effective to provide at least 25,000 particles per 100 g of finished product.

2. The mushroom spawn-supplement of claim 1 wherein the proteinaceous ingredient is selected from the group consisting of corn gluten, feather meal, cracked soybeans, soybean meal, cottonseed meal, and mixtures thereof.

3. The mushroom spawn-supplement of claim 2 wherein the proteinaceous ingredient is corn gluten.

4. The mushroom spawn-supplement of claim 1 further comprising at least one oleaginous ingredient.

5. The mushroom spawn-supplement of claim 4 wherein the oleaginous ingredient is selected from the group consisting of cracked soybeans, soybean fines, sunflowers, cracked sunflowers, and corn oil.

6. The mushroom spawn-supplement of claim 1 wherein the particulate materials are selected from the group consisting of calcined earth, vermiculite, perlite, and mixtures thereof.

7. The mushroom spawn-supplement of claim 1 further comprising (f) gypsum in an amount effective to reduce clumping.

8. The mushroom spawn-supplement of claim 1 comprising on a dry weight basis:

5 to 80 wt % of the proteinaceous ingredient, 2 to 30 wt % of the paper pellets, 5 to 60 wt % of the particulate material, 1 to 12 wt % CaCO₃, and between 40 and 54% water.

9. The mushroom spawn-supplement of claim 8 further comprising 1 to 10 wt % CaSO₄.

10. The mushroom spawn-supplement of claim 8 comprising 6 to 9 wt % CaCO₃.

11. The mushroom spawn-supplement of claim 1 wherein 80% of the paper pellets have a size of between about 0.85 and 4.75 mm.

12. The mushroom spawn-supplement of claim 5 further comprising 1 to 50 wt % grain.

13. The mushroom spawn-supplement of claim 1 wherein the moisture content is between about 46 and 52%.

14. The mushroom spawn-supplement of claim 13 wherein the moisture content is between about 48 and 50%.

15. The mushroom spawn-supplement of claim 1 wherein the proteinaceous ingredients are present in an amount to provide between about 6 and 6.5% nitrogen on a dry weight basis.

16. The mushroom spawn-supplement of claim 1 wherein the buffer is calcium carbonate.

17. The mushroom spawn-supplement of claim 1 wherein the pH is between 6.2 and 7.4.

18. Mushroom compost comprising between 1 and 8% of fresh weight mushroom spawn-supplement of claim 1 based on the dry weight of the compost.

19. The mushroom compost of claim 18 comprising between 4 and 5% of fresh weight of the mushroom spawn-supplement.

20. The mushroom compost of claim 18 further comprising 1 to 6 wt % additional mushroom supplements.

21. The mushroom compost of claim 20 further comprising about 2 wt % additional mushroom supplements.

22. A method of reducing or eliminating mold comprising inoculating the compost with the spawn-supplement of claim 1.

23. The method of claim 22 wherein the mold is green mold disease.

29. The mushroom spawn-supplement of claim 1 wherein the (b) paper pellets, (c) particulate material, or both are present in an amount effective to provide at least 40,000 particles per 100 g of finished product.

24. A method of preparing spawn-supplement comprising colonizing a mixture of:

(a) at least one proteinaceous ingredient in an amount to provide in the spawn-supplement at least 3.5% nitrogen on a dry weight basis;

(b) 2 to 30 wt % based on dry weight of paper pellets;

(c) 5 to 60 wt % based on dry weight of at least one particulate material;

(d) a buffer in an amount effective to provide a pH of about 6 to 7.8; and

(e) water;

with Agaricus bisporus mycelium wherein the (b) paper pellets, (c) particulate material, or both are present in an amount effective to provide at least 25,000 particles per 100 g of finished product.

25. The method of claim 24 further comprising (f) gypsum in an amount effective to reduce clumping.

26. The method of claim 24 wherein the (b) paper pellets, (c) particulate material, or both are present in an amount effective to provide at least 40,000 particles per 100 g of finished product.

27. The method of claim 24 wherein the buffer is calcium carbonate.

28. The method of claim 24 wherein the pH is between 6.2 and 7.4.

30. A mushroom spawn-supplement comprising a mixture of:

(a) at least one proteinaceous ingredient in an amount to provide in the mushroom spawn-supplement at least 1% nitrogen on a dry weight basis;

(b) 2 to 30 wt % based on dry weight of paper pellets;

(c) 5 to 60 wt % based on dry weight of at least one particulate material;

(d) a buffer in an amount effective to provide a pH of about 6 to 7.8; and

(e) water; and

colonized with Agaricus bisporus mycelium wherein the (b) paper pellets, (c) particulate material, or both are present in an amount effective to provide at least 25,000 particles per 100 g of finished product.
