Abstract
Abstract A method of cultivating turf involving use of a first base of close mesh material such as hessian, cotton or synthetic material or a cotton/synthetic mix molded plastics material or knitted, woven or welded plastics such as polyolefin monofilament. Beneath the first base is disposed a second material layer, the material of this second layer being such as to allow roots to grow therethrough and, at harvest, to be withdrawn therethrough. Materials suitable for the second layer include soft textured continuouss materials such as spun polyester or knitted or woven plastics materials. Beneath the second material layer is a sand or sand/aggregate bed which is supported on a perforated plastics sheet. Seeds mixed in a pulp material are disposed on the first base, watered, grown to harvest, and the turf removed with the first base, the second material remaining for re-use.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
A method for cultivation of turf comprising the steps of: a) providing a close mesh base; b) providing under said close mesh base a support of sand or a sand/aggregate mix; c) supporting said sand or sand/aggregate mix on a plastics sheet, introducing grass seeds to said mesh and utilizing a moistening spray over said seeds in order that said seeds might sprout into grass, and said grass may propagate with roots of said propagated grass extending through said close mesh base and into said sand or sand/aggregate mix; and d) lifting the mesh base with the propagated grass extending therethrough from the sand or sand/aggregate mix, thereby removing said roots from the sand or sand/aggregate mix.
Claim 2
Independent Claim
117 words
A method for cultivation of turf comprising the steps of: a) providing a close mesh base; b) providing under said close mesh base a support of sand or a sand/aggregate mix; c) supporting said sand or sand/aggregate mix on a plastics sheet, introducing grass seeds to said mesh and utilizing a moistening spray over said seeds in order that said seeds might sprout into grass, and said grass may propagate with roots of said propagated grass extending through said close mesh base and into said sand or sand/aggregate mix; and d) lifting the mesh base with the propagated grass extending therethrough from the sand or sand/aggregate mix, thereby removing said roots from the sand or sand/aggregate mix.
Claim 3
Dependent Claim
35 words
A method as defined in claim 1 including the further step of disposing between said close mesh base and said base support a further material layer through which grass roots may extend and be withdrawn.
Claim 4
Dependent Claim
21 words
A method as defined in claim 2 wherein said further material layer is of a soft textured material of continuous fiber.
Claim 5
Dependent Claim
16 words
A method as defined in claim 3 wherein said further material layer is of spun polyester.
Claim 6
Dependent Claim
33 words
A method as defined in claim 2 wherein said close mesh base is of hessian, cotton or synthetic material or a cotton/synthetic mix, molded plastics material or knitted, woven or welded polyolefin monofilament.
Claim 7
Dependent Claim
22 words
A method as defined in claim 2 wherein said seed, when deposited on said close mesh base is mixed with pulp material.
Claim 8
Dependent Claim
31 words
A method as defined in claim 6 wherein said pulp material is selected from paper pulp, pine bark, sawdust, shredded sugar cane or a combination of any one or more thereof.
Claim 9
Dependent Claim
19 words
A method as defined in claim 2 wherein said further material layer is of knitted or woven plastics material.
Claim 10
Dependent Claim
21 words
A method as defined in claim 2 wherein said seed, when deposited on said close mesh base is mixed with sludge.
Claim 11
Dependent Claim
16 words
A method as defined in claim 2 wherein said sand or sand/aggregate mix is coarse grained.
Claim 12
Dependent Claim
18 words
A method as defined in claim 2 wherein said plastics material is perforated to allow egress of water.
