Abstract
Abstract A method of growing sod and sod product produced thereby wherein mushroom mulch is used as a growing medium. A seed bed is formed by sowing seeds on the upper surface of a mulch layer. A porous net is placed over the mulch layer to form an anchorage system for the sod root system. Also, a second mulch layer is laid over the sown seeds to protect the seeds and prevent any undesired drying out of the mulch material in closest proximity to the seeds.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
89 words
A method of growing sod comprising the steps of: (a) laying a first relatively thick layer of compost mulch on an inert impervious subsurface to a depth of at least 2 inches. (b) placing a porous net of large mesh size on the upper surface of the compost layer having openings of at least 0.7 square inch, (c) sowing grass seed in the net openings, and (d) overlaying a second relatively thin layer of compost mulch on the seeded net surface to a depth of at least 1 inch.
Claim 2
Independent Claim
89 words
A method of growing sod comprising the steps of: (a) laying a first relatively thick layer of compost mulch on an inert impervious subsurface to a depth of at least 2 inches. (b) placing a porous net of large mesh size on the upper surface of the compost layer having openings of at least 0.7 square inch, (c) sowing grass seed in the net openings, and (d) overlaying a second relatively thin layer of compost mulch on the seeded net surface to a depth of at least 1 inch.
Claim 3
Dependent Claim
21 words
The method of claim 1, wherein: the laying of the first and second compost layers comprises the positioning of mushroom mulch.
Claim 4
Dependent Claim
32 words
The method of claim 1, wherein: the laying of the first and second compost layers comprises the positioning of a growing medium of fermented partially decomposed wheat straw, horse manure, and water.
Claim 5
Dependent Claim
17 words
The method of claim 3, and further including: adding nitrogen to the manure to form microbial proteins.
Claim 6
Dependent Claim
23 words
The method of claim 3, wherein: the compost is provided with a water content of approximately fifty per cent on a weight basis.
Claim 7
Dependent Claim
34 words
The method of claim 1, wherein: the laying of the first and second compost layers comprises the positioning of a first compost layer having a thickness in the range of 21/2 to 3 inches.
Claim 8
Dependent Claim
34 words
The method of claim 1, wherein: the laying of the first and second compost layers comprises the positioning of a second compost layer having a thickness in the range from 1 to 11/2 inches.
Claim 9
Dependent Claim
21 words
The method of claim 1, and further including: providing such openings which are approximately 11/4 inch long and 5/8 inch wide.
Claim 10
Dependent Claim
27 words

Dependent Claim
28 words
A method according to claim 1, wherein: said second thin layer of compost mulch is laid to a depth in the range of about 1 to 11/2 inches.
Claim 12
Dependent Claim
114 words
A sod product, comprising: a first relatively thick lower layer of compost having a depth of at least 2 inches, a porous large mesh size net atop the first compost layer, said porous net defining large openings sized to accommodate extension of grass roots therethrough in intertwining relationship to provide anchoring, said porous net having at least some openings areas of at least 0.7 square inch, a relatively thin upper layer of compost above the porous net having a depth of at least 1 inch, and grass plants having basal node areas thereof located at about the porous net plane to form anchorages for the roots that extend into the lower layer of compost.
Claim 13
Dependent Claim
114 words
A sod product, comprising: a first relatively thick lower layer of compost having a depth of at least 2 inches, a porous large mesh size net atop the first compost layer, said porous net defining large openings sized to accommodate extension of grass roots therethrough in intertwining relationship to provide anchoring, said porous net having at least some openings areas of at least 0.7 square inch, a relatively thin upper layer of compost above the porous net having a depth of at least 1 inch, and grass plants having basal node areas thereof located at about the porous net plane to form anchorages for the roots that extend into the lower layer of compost.
Claim 14
Dependent Claim
20 words
A sod product according to claim 11, and further including: an inert impervious sub-surface sheet under said lower compost layer.
Claim 15
Dependent Claim
14 words
