[0039] In one embodiment, this method only uses atmospheric moisture or evaporation.

[0040] FIG. 1 shows the features of the furrow design for a planted seed:

TABLE-US-00001 FIG. 1 No. Description 101 Crop Penetration through top cover 102 Optional Cover Vent 103 Top Cover 104 Finish Grade Original Soil 106 Dirt Cover (2 -3) 108 Planting Soil Mix 109 Plastic Ground Cover 110 Wire Frame 111 Drip Line 116 Light (LED or Incandescent) on a Tape or Rope for growth or heat 117 Tap Root Penetration 118 Seed or seed Tape

[0041] The top cover 103 is made from an impermeable plastic or cloth and is installed onto a metal frame. The cloth may incorporate a coating that is useful for trapping moisture. The metal frame is a loop shape as indicated, and installed approximately every 4-6 feet. The top cover 103 acts like a solar screen and prevents evaporation. It also protects from birds, bugs, wind, hail and frost.

[0042] The crop penetrates 101 through the top cover which includes perforations that are designed to allow the plant to penetrate as it grows larger.

[0043] An optional cover vent 102 opens to control the air temperature underneath the cover when it is too hot. This is especially useful when the top cover 103 is an impermeable plastic. If the top cover is a permeable material, a vent may or may not be needed depending upon the temperature underneath the top cover.

[0044] A finished grade from original soil 104 is shaped into a furrow as illustrated.

[0045] The planting soil mix 108 is made from a combination of native soil, a water absorbing polymer, and at least one additional potting medium which may be organic or inorganic. Suitable potting mediums include vermiculite, perlite, sand, silt, peat, charcoal, loam, fertilizer, compost, humus, manure, bone meal, blood meal, alfalfa meal, cottonseed meal, crab meal, feather meal, fish meal, soybean meal, kelp meal, granite meal, greensand, bat guano, seabird guano, colloidal phosphate, rock phosphate, wood ash, worm, castings, ground limestone, pine bark, spaghnum peat moss, coir, alfalfa, kenaf, sawdust, ground newspaper, clay, and leaf mold. In one embodiment, the water absorbing polymer gel is a polyacrylate. A product name for this is Stockosorb 660. Alternately, other water absorbing polymers (PAM) could be used.

[0046] As a practical matter a seed or seed tape 118 is used to establish the plant. This is a convenient way to plant crops a desired distance apart.

[0047] An impervious plastic ground cover 109 controls water migration to the soil below, and prevents bugs.

[0048] The wire frame 110 is made from galvanized wire and moves outwardly as the plant grows. This is illustrated in FIGS. 3A-3B.

[0049] A drip line 111 with drip emitters are installed on the drip line at intervals to control the volume of water into the furrow, and is optionally pressure compensated. Drip emitters are installed at intervals along the length of the furrow. A drip emitter is preferably a pipe with spaced slots or an orifice.

[0050] An incandescent or L.E.D. light 116 is used to provide light and increase the soil temperature frost protection from the heat generated by the light. This is especially useful in extending the growing season by providing earlier seed germination with warmer ground temperatures during the colder weather and when there is a lesser amount of sunlight. The light could be powered by a high or voltage, and is optionally solar powered. Some important crops germinate at 56 F.

[0051] A portion of the plastic ground cover is slotted 117 to allow the plant roots to push through.

[0052] A lower watering area receives water after plant roots push through the plastic ground cover. Crop watering is phased in as the plant grows. The amount of water used depends upon a number of factors, including the plant maturity, amount of rainfall, and the time of year.

[0053] The embodied invention also reduces fertilizer consumption because there is less runoff and migration into the lower soil. Similarly, the amount of pesticide is reduced due to lower watering on the top of the crop, and the top cover helps to prevent pests.

[0054] If the plant crops are located near seawater, the seawater can be purified to usable water for crops by a method known in the art. The need for a low amount of water per acre of crop reduces volume required for watering when a sea-water or brackish water is used.

[0055] Purified water can be generated by a mechanical filter system, a distillation system, a solar based evaporative system, or a chemical processing method to remove impurities and ions to make it suitable for use. Chemical processing systems include distillation, capacitive deionization, reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation, and electro-deionization.

[0056] The top cover acts as a solar shield and protects the crop from snow and hail. It alsoreduces water evaporation by 10 To 15% by protecting the crop from wind and sun. It also is able to extend the growing system up to 12 weeks by protecting the plants from frost, freezing, and hail.

[0057] FIG. 2 shows the features of the furrow design, situated in a saltwater or brackish water field, designed similarly to FIG. 1.

TABLE-US-00002 FIG. 2 No Description 201 Crop Penetration 202 Optional Cover Vent 203 Top Cover Over Wire Frame 204 Finish Grade Original Soil 205 Planting Soil Mix 206 Plastic Ground Cover 207 Wire Frame 208 Drip Line 209 Seed tape 210 Riser 212 Light (LED or Incandescent) on a Tape or Rope 213 Tap Root Penetration 218 Plastic coated cloth (Dewetting) 219 Small Water Vapors 220 Condensate-Fresh Water Drips 222 Polymer Nano Carbon Tubes

[0058] The top cover 203 is made from an impermeable plastic or cloth and is installed onto a metal frame. The cloth may incorporate a coating that is useful for trapping moisture. The metal frame is an elongated loop shape as indicated, and installed approximately every 4-6 feet. The top cover 203 acts like a solar screen and prevents evaporation. It also protects from birds, bugs, wind, hail and frost.

[0059] The crop penetrates 201 through the top cover which is designed to allow the plant to penetrate as it grows larger.

[0060] An optional cover vent 202 opens with higher temperature to control the air temperature underneath the cover. This is especially useful when the top cover 203 is an impermeable plastic. If the top cover is a permeable material, a vent may or may not be needed depending upon the temperature underneath the top cover.

[0061] The original soil 204 is shaped as indicated. The planting soil mix 205 is made from a combination of native soil, a water absorbing polymer, and at least one additional potting medium which may be organic or inorganic. Suitable potting mediums include vermiculite, perlite, sand, silt, peat, charcoal, loam, fertilizer, compost, humus, manure, bone meal, blood meal, alfalfa meal, cottonseed meal, crab meal, feather meal, fish meal, soybean meal, kelp meal, granite meal, greensand, bat guano, seabird guano, colloidal phosphate, rock phosphate, wood ash, worm, castings, ground limestone, pine bark, spaghnum peat moss, coir, alfalfa, kenaf, sawdust, ground newspaper, clay, and leaf mold. In one embodiment, the water absorbing polymer gel is polyacrylate. Other water absorbing polymers (PAM) could alternately be used.

[0062] The original soil 204 is shaped into a furrow as illustrated. The soil is left undisturbed as much as practical.

[0063] An impervious plastic ground cover 206 controls water migration to the soil below, and prevents bugs. Only a temporary protection is needed for a young plant. Young plant roots are more vulnerable, but later in the growth cycle, the plant roots do not need the protection.

[0064] The wire frame 207 is made from galvanized wire and moves outwardly in a natural manner when the plant grows. An optional friction release can be added to the wire frame at the soil level to allow the upper portion of the frame to disconnect from the lower portion of the frame. This allows the frame to expand more easily and allow room for the plant to grow. It additionally provides an extended period of frost protection.

[0065] As a practical matter a seed tape 209 is used to establish the plant. This is a convenient way to plant crops a desired distance apart.

[0066] A drip line 208 provides controlled amounts of water as needed to saturate around plant roots only. The drip emitter is used to control the volume of water into the furrow, and is optionally pressure compensated. Drip emitters are installed at intervals along the length of the furrow. The drip emitter is preferably a pipe with spaced slots or an orifice.

[0067] The irrigation system is used whenever the water condensate from the adjacent seawater, (or brackish) basin does not provide adequate moisture for crop growth. Water condensate can come from fog, dew, or high humidity as well.

[0068] An incandescent or L.E.D. Light 212 mounted on a tape is used to provide light and increase the soil temperature from the heat generated by the light. This is especially useful in extending the growing season by providing earlier seed germination with warmer ground temperatures during the colder weather and when there is a lesser amount of sunlight. The light could be powered by a high or low voltage, and is optionally solar powered.

[0069] A portion of the plastic ground cover is slotted 213 to allow the plant roots to push through.

[0070] The moist atmosphere (misty or highly humid) above the water collects small water vapors 219 onto a fabric coated with a polyacrylate de-wetting system 218, which collects the water vapors into drops of fresh condensate 220 onto the top cover. The water then drops below the cover and waters the plant. Polymer Carbon Nano Tubes 222 assist the water formation.

[0071] FIGS. 3A-3B show how the furrow dimensions expand and grow based on the growth of the plant root system. The initial furrow geometry is not held in place by rods or stakes that are anchored into the soil. Instead, the initial furrow geometry is allowed to change based on the pressure of the root ball and the wire frames that support the top cover are allowed to move when the sides of the furrow move.

[0072] FIG. 4 shows the concept of watering in phases depending upon the growth of the plant. In phase I, the watering schedule is restricted so that only the immediate area around the seed or root ball receives the moisture needed for germination/ growth.

[0073] As an alternate embodiment, the polyacrylate could be a polymer that would satisfy the definition of organic farming. Such a polymer could be Polysaccharide (which is a modified cellulose/sugar/starch base PAM like Biosap). This would allow the methods taught in this disclosure to reach a broader farming market, and an important one for many consumers.

[0074] FIGS. 5A-5C show alternate embodied geometries for the plant furrow and frame geometry based on the type of plant that will be grown. In FIG. 5A, typical rows of strawberries, cabbage, lettuce (Type A) 501 can be grown under the cover and in the furrow geometry. Multiple grouping of the crop furrows remain under the crop cover 502.

[0075] In FIG. 5B, tomato type produce including fruit trees, and corn, are grown under the cover 503 and in the furrow geometry. The plant penetrates the plastic ground cover at the root system. The plant stalk grows through 504 the domed cover. An optional metal frame support 505 can be included for tomato type produce to support the plant.

[0076] In FIG. 5C, root type produce, such as potatoes are grown under the cover. The plant remains under cover and in the furrow geometry. This type of arrangement is suitable for root plants 506 such as potatoes, melons, and squash.

[0077] In FIG. 5D, a reusable wire cage 33 grid 507 is hinged 508 to allow the lid to open for access. A latch pin 509 is used to keep the lid closed.

[0078] While various embodiments of the embodied invention have been described, the invention may be modified and adapted to various operational methods to those skilled in the art. Therefore, this invention is not limited to the description and figure shown herein, and includes all such embodiments, changes, and modifications that are encompassed by the scope of the claims.
