Revegetation Process
A method for revegetation or remediation of a land surface in which a layer containing selected seed, mulch and nutrients is applied to the land surface. More specifically, the layer applied contains grain seed, grass seed or both and the rate of seeding is preferably 100 lbs/acre or more. The method preferably includes after-care steps in which growth stimulating or growth maintenance compositions are applied to the land that has been seeded using the layer application.
1 . A method for revegetation or remediation of a land surface in need of such revegetation or remediation comprising the steps:
(a) applying a layer containing a selected composition of grain seed, grass seed or both, mulch, and selected nutrients to the land surface;
(b) periodically applying to the layer a growth stimulating composition which comprises one or more plant growth factors;
(c) periodically applying to the layer a growth maintenance composition which comprises nitrogen, but no plant growth factors;
wherein the application of step (a) is repeated until a desired level of surface coverage of growing grain, grass or both is achieved and wherein steps (b) and (c) are repeated on an alternating basis to achieve a desired level of growth.
2 . The method of claim 1 wherein the grain seed applied to the land surface is applied at a rate of 100 lbs/acre or more.
3 . The method of claim 1 wherein the seed mixture predominantly contains native grass seed.
4 . The method of claim 2 wherein the seed mixture predominantly contains native grass seed.
5 . The method of claim 1 wherein the grain seed applied is barley seed.
6 . The method of claim 2 wherein the grain seed applied is barley seed.
7 . The method of claim 1 wherein the grain seed is combined with native grass seed.
8 . The method of claim 2 wherein the grain seed is combined with native grass seed.
9 . The method of claim 1 wherein the application step (a) is repeated two or more times.
10 . The method of claim 1 wherein the layer applied in step (a) comprises one or more gibberellins, one or more humates or a mixture thereof.
11 . The method of claim 1 wherein the growth stimulating composition comprises one or more gibberellins.
12 . The method of claim 1 wherein the mulch comprises straw, hay or cut native grass.
13 . The method of claim 2 wherein the mulch comprises straw, hay or cut native grass.
14 . The method of claim 13 wherein the seed mixture contains native grass seed and grain seed.
15 . The method of claim 14 wherein the growth stimulating composition comprises one or more gibberellins.
16 . The method of claim 15 wherein the application step (a) is repeated two or more times.
17 . The method of claim 16 wherein the layer applied in step (a) is sprayed as a hydromulch.
18 . The method of claim 1 wherein the layer applied in step further comprises seed and/or seedlings of trees or shrubs.
19 . The method of claim 1 wherein the layer applied in step (a) is sprayed as a hydromulch.
20 . The method of claim 1 wherein the layer applied in step (a) further comprises seaweed.
