Device for delivering plant seeds
A seed delivery device that includes an enclosed container inside which is encapsulated one or more plant seeds and a medium. The medium may comprise one or more particulate materials, one or more aqueous materials, or a combination of one or more particulate materials and aqueous materials. The specific gravity of the entire device is greater than the specific gravity of water. The seed delivery devices may be used to address the planting of seeds in conditions where water is or may become present.
1. An article comprising a seed delivery device having:
(a) a water dissolvable container having an internal space for holding materials, the water dissolvable container encapsulating materials placed in the internal space,
(b) one or more plant seeds in the internal space of the water dissolvable container, and
(c) a medium having one or more particulate materials, one or more aqueous materials, or a combination of the one or more particulate materials and the aqueous materials in the internal space of the water dissolvable container, wherein the medium comprises materials that are differentiable from the water dissolvable container and has a density sufficient to form a seed delivery device having a specific gravity greater than water,
(d) wherein at least a portion of the water dissolvable container dissolves upon exposure to adequate water moisture and exposes the medium to water moisture to form a moistened medium,
(e) wherein the moistened medium is comprised of materials that affix the one or more plant seeds to at least a portion of the moistened medium to form one or more particles, the one or more particles having a specific gravity greater than water, and
(f) wherein the one or more plant seeds remain affixed to the one or more particles when the one or more particles are inundated or submerged in water and the water dissolvable container has dissolved completely.
2. An article according to claim 1 , wherein the water dissolvable container, upon contact with water, decomposes, breaks apart, breaks down, disintegrates, disperses, hydrolyzes, at least partial states thereof or combinations thereof.
3. An article according to claim 1 , wherein the water dissolvable container once exposed to adequate water moisture affixes both the one or more plant seeds to the medium and the medium to a substrate to enable germination of the one or more seeds.
4. An article according to claim 1 , wherein the water dissolvable container comprises (i) a capsule made in two halves, one half having a smaller diameter body that is closed on one end, and the other half having a larger diameter cap that is also closed on one end that, wherein the two halves when joined seal the water dissolvable container, or (ii) a capsule made of one or more sheets that is sealed along a seam.
5. An article according to claim 1 , wherein the water dissolvable container comprises a sealed pod, or a pouch.
6. An article according to claim 1 , wherein the water dissolvable container is made from one or more of an aqueous solution of gelling agents, animal proteins, a polysaccharide, a derivative of a polysaccharide, or polyvinyl alcohol.
7. An article according to claim 1 , further comprising anti-herbivory or anti-tampering compounds located within or upon the water dissolvable container.
8. An article according to claim 1 , wherein the one or more plant seeds are coated.
9. An article according to claim 1 , wherein the plant seed comprises an aquatic plant, a plant that grows in saturated conditions, a plant that grows in terrestrial conditions, a genetically modified plant, an ornamental plant, a crop plant, a plant grown for ecological purposes, a grass plant, a sedge plant, a rush plant, a forb plant, a vine plant, a shrub plant, a tree, or a cactus.
10. An article according to claim 1 , wherein the medium comprises one or more of crushed stone, iron filings, sand, soil, vermiculite, compost, crushed shells of invertebrates, compost, soil, peat, vermiculite, clay, polymer, fertilizer, pesticide, fungicide, anti-herbivore compound, anti-tampering compound, chemical buffering agent, soil conditioner or combinations thereof.
11. An article according to claim 10 , wherein the polymer comprises a natural material, a synthetic material, or a biodegradable material.
12. An article according to claim 1 , wherein one or more of the particulate materials retains water moisture within the one or more particles.
13. An article according to claim 1 , wherein the medium comprises organisms that provide a biological function for plant seeds or the resulting plants after germination, including one or more of bacteria, fungi, viruses, or protozoa.
14. A method comprising delivering a plurality of the seed delivery devices of claim 1 to a substrate to promote plant growth.
15. A method according to claim 14 , wherein the substrate comprises an aquatic substrate, a moist or saturated substrate, or a dry or terrestrial substrate.
16. A method according to claim 14 , wherein the plurality of seed delivery devices affix plant seeds to the medium and the medium to the substrate to enable germination of the one or more seeds.
17. A method according to claim 14 , wherein the water dissolvable container of the seed delivery device comprises (i) a capsule made in two halves, one half having a smaller diameter body that is closed on one end, and the other half having a larger diameter cap that is also closed on one end that, wherein the two halves when joined seal the water dissolvable container, (ii) a capsule made of one or more sheets that is sealed along a seam, or (iii) a sealed pod, or a pouch.
18. A method according to claim 14 , wherein delivering the plurality of seed delivery devices comprises manual distribution, mechanical distribution, hand casting, broadcasting, distribution by water craft, amphibious vehicle, terrestrial vehicle, or aircraft.
19. A method comprising:
(a) providing a water dissolvable container having an internal space for holding materials, the water dissolvable container encapsulating materials placed in the internal space,
(b) encapsulating (i) one or more plant seeds and (ii) a medium having one or more particulate materials, one or more aqueous materials, or a combination of the one or more particulate materials and the aqueous materials in the internal space of the water dissolvable container to form a seed delivery device, wherein the medium comprises materials that are differentiable from the water dissolvable container and has a density sufficient to form a seed delivery device with a specific gravity greater than water;
(c) exposing the water dissolvable container to water moisture such that it at least partially dissolves and exposes the medium to water moisture to form a moistened medium;
(d) wherein the moistened medium is comprised of materials that affix the one or more plant seeds to at least a portion of the moistened medium to form one or more particles, the one or more particles having a specific gravity greater than water; and
(e) wherein the one or more plant seeds remain affixed to the one or more particles when the one or more particles are inundated or submerged in water and the water dissolvable container has dissolved completely.
