Abstract

Cellulose filament medium for growing plant seedlings, comprising mixture of water and cellulose filaments, the cellulose filaments being at a consistency of between about 4% and 50% in the mixture. Composition of matter suitable for forming a cellulose filament medium for growing plant seedlings, comprising: mixture of water and cellulose filaments, the cellulose filaments being at a consistency of between about 28% and 35% in the mixture. Method of forming a medium for growing plant seedlings, comprising: adding a sufficient amount of water to a mixture of water and cellulose filaments, the cellulose filaments being at a consistency of between about 28% and 35% in the mixture, to lower the consistency to between about 14% to 27%. Method of growing plant seedlings comprising: implanting plant seeds in a mixture of water and cellulose filaments, the cellulose filaments being at a consistency of between about 4% and 50% in the mixture.

Claims (6)

1 . A method of forming a plant seedlings growth composition, comprising: preparing a mixture of cellulose filaments, one or more cation exchange capacity enhancers and an aqueous liquid, the cellulose filaments being at a consistency of between 36% and 50% in the mixture and further lowering the consistency to between about 28% to 35% in the mixture, wherein the cation exchange capacity of the mixture is 10 or above.

2 . The method of claim 1 , further comprising further lowering the consistency of the cellulose filaments to about 14% to 25% in the mixture.

3 . The method of claim 1 , wherein the cellulose filaments are unbleached.

4 . The method of claim 1 , wherein the cellulose filaments are untreated.

5 . The method of claim 4 , further comprising treating the cellulose filaments to enhance the cation exchange capacity of the mixture, wherein the treating comprises derivatizing the cellulose filaments.

6 . The method of claim 1 , wherein the cellulose filaments have an average aspect ratio from about 200 to about 5000; an average width from about 30 nm to about 500 nm; and an average length of about 200 μm to about 2 mm.
