Abstract
Abstract The invention concerns a fertilizer to enhance the mycorhization and the fructification of mycorhizal mushrooms, in particular the tuber melanosporum. This fertilizer includes a mixture of non-ferment organic substances of animal origin (ovine excrements, fowl droppings, dried blood or feather powder), of organic substances of vegetable origin and essentially proteins and carbohydrates (in particular grains, flours, oil or cattle cakes or vegetable wastes from soy, cotton, wheat, rice, ricinus) and at least one alkalizing compound suitable to provide the mixture with a pH higher than 8; the mutual proportions of the ingredients are adjusted so that the C/N ration of the mixture is at least 10.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
95 words
A fertilizer for enhancing the mycorhization and/or the fructification of mycorhizal mushrooms selected from the group consisting of tuber melanosporum, consisting essentially of a mixture of non-fermented organic substances of animal origin, organic substances of proteins and carbohydrates of vegetable origin, and at least one alkalizing compound selected from the group consisting of calcium compounds for raising the pH value of the mixture so that the mixture has a pH value greater than 8, the mutual proportions of the organic substances being adjusted so that the mixture has a C/N ratio of at least 10.
Claim 2
Dependent Claim
95 words
A fertilizer for enhancing the mycorhization and/or the fructification of mycorhizal mushrooms selected from the group consisting of tuber melanosporum, consisting essentially of a mixture of non-fermented organic substances of animal origin, organic substances of proteins and carbohydrates of vegetable origin, and at least one alkalizing compound selected from the group consisting of calcium compounds for raising the pH value of the mixture so that the mixture has a pH value greater than 8, the mutual proportions of the organic substances being adjusted so that the mixture has a C/N ratio of at least 10.

Claim 15
Dependent Claim
106 words
A process for fertilizing truffle beds for enhancing mycorhization and/or fructification of mycorhizal mushrooms selected from the group consisting of tuber melanosporum, comprising spreading on the bed at a rate of about 0.3 to 3 kg/m 2 a fertilizer having a pH of at least 8 and consisting essentially of a mixture of non-fermented organic substances of animal origin, organic substances of proteins and carbohydrates of vegetable origin, and at least one alkalizing compound for raising the pH of the mixture to greater than 8, the mutual proportions of the organic substances being adjusted so that the mixture has a C/N ratio of at least 10.
Claim 16
Dependent Claim
106 words
A process for fertilizing truffle beds for enhancing mycorhization and/or fructification of mycorhizal mushrooms selected from the group consisting of tuber melanosporum, comprising spreading on the bed at a rate of about 0.3 to 3 kg/m 2 a fertilizer having a pH of at least 8 and consisting essentially of a mixture of non-fermented organic substances of animal origin, organic substances of proteins and carbohydrates of vegetable origin, and at least one alkalizing compound for raising the pH of the mixture to greater than 8, the mutual proportions of the organic substances being adjusted so that the mixture has a C/N ratio of at least 10.
Claim 17
Dependent Claim
37 words

Claim 18
Dependent Claim
62 words
A fertilizing process as in claim 14 and wherein said fertilizer has a pH of about 10 to 13.5 and a C/N ratio of about 11 to 14, and applying said fertilizer at a rate such as to raise the pH of the soil to about 8 to 9 and the C/N ratio of the soil is between about 10 and 12.
