Materials suitable as substitutes for peat mosses and processes and apparatus therefor
Processes capable of producing bulk materials suitable for use by the horticulture industry, resulting bulk materials produced thereby, and applications for these processes and materials. Preferred bulk materials have physical properties similar to peat moss and comprise individual materials, each at least partially having a twisted, curled, clumped and rolled structure. The individual materials may further comprise small granular particles dispersed throughout the twisted, curled, clumped and rolled structure. The individual materials may be rolled fibers such that the bulk material has physical properties similar to Sphagnum peat moss so as to be particularly suitable as, for example, a soil conditioner, an absorbent material, a chemical carrier, or a filtering material. Alternatively, the individual materials may be rolled particles such that the bulk material has physical properties similar to milled peat moss so as to be particularly suitable as propagation media.
1. A bulk material for use in the horticulture industry as a substitute for Sphagnum peat moss and having a bulk density of 70 to 150 grams per liter and physical properties that enable the bulk material to be mixed into soil in order to promote moisture retention and enhance aeration in the soil and/or used as media for propagation, seed starting and/or rooting applications, the bulk material comprising porous individual materials having a rolled form, each porous individual material comprising abrasive small granular particles (SGPs) dispersed in a core comprising rearranged shredded fragments of a cellulose material and having an internal fibrous structure, porosity characterized by internal pores for moisture-holding, and an external structure comprising the following shapes: twisted, curled, and clumped;
wherein:
the core has a coiled structure with overlapping portions;
all of the SGPs are individually distributed and dispersed throughout the internal fibrous structures and the external structures of the cores and between the overlapping portions of the cores;
at least some of the SGPs are confined within the cores;
the bulk material has a texture of Sphagnum peat moss; and
the SGPs are a size of about 1/16 to about 1 mm.
2. The bulk material as recited in claim 1 , wherein the SGPs comprise gypsum.
3. The bulk material as recited in claim 1 , wherein the largest dimensions of the porous individual materials do not exceed eight millimeters.
4. The bulk material as recited in claim 1 , wherein the bulk material is a soil conditioner.
5. The bulk material as recited in claim 1 , wherein the bulk material is a propagation media.
6. The bulk material as recited in claim 1 , wherein the bulk material is an absorbent material.
7. The bulk material as recited in claim 1 , wherein the bulk material is a chemical carrier.
8. The bulk material as recited in claim 1 , wherein the bulk material is a filtering material.
9. The bulk material as recited in claim 1 , wherein the bulk material consists of the porous individual materials.
10. The bulk material as recited in claim 1 , wherein the bulk material has a moisture-holding capacity that by weight exceeds Sphagnum peat moss.
11. The bulk material as recited in claim 1 , wherein the SGPs comprise a solid material that remains solid or fragments or dissolves during use of the bulk material.
12. The bulk material as recited in claim 1 , wherein the SGPs comprise one or more of hoof and horn materials, ground shells, ground pits, ground seeds, coffee grounds, chaff, hulls, brewery waste, granulated products of fermenting and fuel production, ground shells, ground or processed forestry products, calcined clay, sand, fused earth products, pumice, volcanic ash, perlite, vermiculite, gypsum, lime, fertilizer, coal fines, rock dust, ground glass, concrete, asphalt, metal, food service containers, solidified fibers, plastics, and processed plastics.
