Abstract

Abstract A horticultural device utilizing magnetism for raising plants includes a plate-shaped section in which a fertilizer is imbedded, and a rod-shaped section extending from the bottom side of the plate-shaped section and having a fluid flow passageway, at least a portion of the device having a magnetic property. The rod-shaped section is thrust into soil surrounding a plant until the plant-shaped section contacts the soil surface. The fertilizer carried in the plate-shaped section is gradually dissolved and converted into a magnetized fertilizer solution by watering, the fertilizer solution dispersing itself into the soil through the liquid flow passageway of the rod-shaped section.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 145 words
A horticultural device utilizing magnetism for insertion into the soil adjacent a plant comprising; a plate-shaped section for receiving water having top and bottom sides and a plurality of holes extending therethrough; at least one rod-shaped section extending downwardly from the bottom side of the plate-shaped section and having a liquid flow passageway extending through the rod-shaped section that is open at both ends, said rod-shaped section containing magnetized metal powder, whereby a portion of the water received by the plate-shaped section flows down through the passageway and is magnetized before flowing out into the soil; and a sheet of compressed fertilizer adhered to the bottom side of the plate-shaped section and covering said holes whereby a portion of the water received in the plate-shaped section also passes through said holes and gradually dissolves the fertilizer before passing into the soil as a fertilizer solution.
Claim 2
Dependent Claim 145 words
A horticultural device utilizing magnetism for insertion into the soil adjacent a plant comprising; a plate-shaped section for receiving water having top and bottom sides and a plurality of holes extending therethrough; at least one rod-shaped section extending downwardly from the bottom side of the plate-shaped section and having a liquid flow passageway extending through the rod-shaped section that is open at both ends, said rod-shaped section containing magnetized metal powder, whereby a portion of the water received by the plate-shaped section flows down through the passageway and is magnetized before flowing out into the soil; and a sheet of compressed fertilizer adhered to the bottom side of the plate-shaped section and covering said holes whereby a portion of the water received in the plate-shaped section also passes through said holes and gradually dissolves the fertilizer before passing into the soil as a fertilizer solution.
Claim 3
Dependent Claim 20 words
The device of claim 1, wherein the plate-shaped section also contains magnetized metal powder to provide a magnetized fertilizer solution.
Claim 4
Dependent Claim 24 words
The device of claim 2, wherein the plate-shaped section and the rod-shaped section are integrally molded of a plastic containing the magnetized metal powder.
Claim 5
Dependent Claim 31 words
The device of claim 2, wherein the upper end of the rod-shaped section and the plate-shaped section have north polarity and the lower end of the rod-shaped section has south polarity.
Claim 6
Dependent Claim 18 words
The device of claim 1, wherein the plate-shaped section is dish shaped to hold a supply of water.
Claim 7
Dependent Claim 21 words
The device of claim 1, wherein the plate-shaped section has a circumferentially extending raised edge to hold a supply of water.
Claim 8
Dependent Claim 19 words
The device of claim 1, having one rod-shaped section that extends downwardly from the center of the plate-shaped section.
Claim 9
Dependent Claim 27 words
The device of claim 7 wherein the plate-shaped section has a plurality of radially extending grooves that channel the water to the passageway in the rod-shaped section.
