Description
A SEED PLANTING AND NUTRITION DEVICE
The present invention relates to a seed planting and nutrition device for holding and automatically feeding seeds when watered.
Much time and effbrt, especially in the agricultural field, has been put into developing machinery for planting seeds in reasonably uniform predetermined spaced relationship. If machinery is not utilised, seed planting has to be performed manually, which is time-consuming and back-breaking work.
Once the seeds are planted, a feed substance, such as fertiliser or other growth promoting additive is then typically applied to the ground or soil in which the seeds are located.
The present invention seeks to overcome these difficulties whilst dispensing with the need for specialised, high cost machinery.
According to a first aspect of the present invention, there is provided a seed planting and nutrition device for holding plant seeds in spaced relationship, the device comprising a biodegradable liquid soluble element including poly vinyl alcohol (PVA); a plurality of seeds held on or in the liquid soluble element in predetermined spaced relationship; and a complementary feed substance provided on or in the liquid soluble element, so that in use, as the liquid soluble element dissolves, the seeds are released and the feed substance is released automatically providing nutrition for the seeds.
Preferable andlor optional features of the first aspect of the invention are set forth in claims 2 to 10, inclusive.
According to a second aspect of the present invention, there is provided a method of planting seeds, the method comprising the steps of: a) locating a seed planting and nutrition device, in accordance with the first aspect of the invention, on top of a lower layer of soil; b) covering the seed planting and nutrition device with an upper layer of soil; and c) watering the upper layer of soil sufficiently to wet the seed planting and nutrition device, so that, as the liquid soluble element dissolves, the seeds are released and the feed substance is released thereby automatically feeding the seeds.
Preferably, in step (a), the liquid soluble element of the seed planting and nutrition device is unrolled or unfolded onto the lower layer of soil, so that the plurality of seeds automatically assume a predetermined spaced relationship.
The present invention will now be more particularly described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a diagrammatic perspective view of a first embodiment of a seed planting and nutrition device, in accordance with the first aspect of the invention; Figure 2 is a cross-sectional view taken along the line A-A in Figure 1; Figure 3 is a diagrammatic view of the seed planting and nutrition device in use and in accordance with the second aspect of the invention; Figure 4 is a diagrammatic cross-sectional view of the seed planting and nutrition device releasing a feed substance following contact with water;
S
Figure 5 is a diagrammatic cross-sectional view of a second embodiment of a seed planting and nutrition device, in accordance with the first aspect of the invention; and Figure 6 is a diagrammatic cross-sectional view of a third embodiment of a seed planting and nutrition device, in accordance with the first aspect of the invention.
Referring firstly to Figures 1 to 4 of the drawings, there is shown a seed planting and nutrition device 10 which comprises a planar or substantially planar liquid soluble film sheet 12, a plurality of seeds 14, and a feed substance 16.
The liquid soluble sheet 12 is typically water soluble and is or includes poly vinyl alcohol (PVA), which easily biodegrades without environmental damage. As such, the liquid soluble sheet 12 can be entirely formed from PVA, or may be formed from a blend of compounds including PVA. For example, a suitable blend is PVA and polysaccharide, such as Pectin. The polysaccharide increases the strength of the sheet 12, and also increases the biodegradability of the PVA. Plasticisers can also be included to increase the flexibility of the sheet 12. The liquid soluble sheet 12 is thus filly biodegradable, resulting in only naturally occurring and thus environmentally friendly products when broken down.
During production of the liquid soluble sheet 12, which can be, for example, blow moulded, extruded, andlor injection moulded, a feed substance 16 is mixed in. The feed substance 16 is typically a fertiliser or growth promoting additive, and is specifically chosen to complement the plurality of seeds 14 to be used. For example, if the seeds are tomato seeds, then the feed substance will be tomato feed.
Once the feed substance 16 is mixed in, and before the liquid soluble sheet 12 fi.illy sets or cures, the plurality of chosen seeds 14 are positioned on the liquid soluble sheet 12 so that they bond or adhere to the sheet 12 during the final stages of the setting or curing process.
It is also envisaged that the seeds 14 can be mixed in during the production of the liquid soluble sheet 12, at a similar stage in the process at which the feed substance 16 is added. However, care must be taken not to induce growth in the seeds 14 prior to location in the ground.
Furthermore, locating the seeds 14 on the liquid soluble sheet 12 allows a predetermined uniform or substantially uniform spaced relationship between adjacent seeds 14 to be imparted, such as alignment in rows and columns. Such a spaced relationship is less assured if the seeds 14 are mixed in at the time of adding the feed substance 16.
In a modification, the liquid soluble sheet, once set or cured, can be coated with an adhesive or bonding agent (not shown). The bonding agent may act as a film, covering the plurality of seeds and thus bonding them to the liquid soluble sheet.
Alternatively, the bonding agent can be applied to a surface of the liquid soluble sheet, with the seeds then being located thereon and consequently retained in place following setting of the bonding agent. The bonding agent is also fully water soluble.
In use, the sheet 12 is rolled or folded for transportation and storage. Once at a desired location, a top layer of soil 18 is first removed, typically forming furrows 20 as shown in Figure 3, and the liquid soluble sheet 12 is unrolled or unfolded onto a lower layer of soil 22 so as to extend along and over the furrows 20. The plurality of seeds 14 are thus automatically positioned to lie in spaced relationship along the furrows 20. The top layer of soil 18 is re-applied over the liquid soluble sheet 12, and watering is commenced.
As can be appreciated from Figure 4, following exposure to moisture, such as through watering, growth of the seeds 14 is initiated and the liquid soluble sheet 12 dissolves, thereby releasing the feed substance 16 into the surrounding soil and providing localised and targeted growth promoting nutrition for the seeds 14.
Although furrows 20 are suggested, since these can be easily produced with existing agricultural equipment, providing a layer of top soil is applied to cover or substantially cover the seeds 14 to provide for a normal moist and enclosed environment to promote growth, then the seed planting and nutrition device 10 can be positioned almost anywhere and in any configuration. It is also quite feasible to dictate the required spacing of the seeds 14 when they are being applied to the liquid soluble sheet 12, so that specific spacings and area coverage are produced.
It is also possible to form the seeds 14 into patterns as they are being applied to the liquid soluble sheet 12, thus allowing ornamental displays to be easily laid. It is envisaged that the placement of the seeds 14 on the liquid soluble sheet 12 can be computer controlled, thus allowing substantially any arrangement and pattern to be implemented.
Regarding Figure 5, a second embodiment of a seed planting and nutrition device 110 is shown. This device corresponds closely to the first embodiment described above, and the various modifications mentioned previously are also applicable. As such, similar numbers refer to similar parts, and further detailed description is omitted.
In this embodiment, a plurality of seeds 114 are encased or sandwiched between upper and lower layers 124, 126 of a liquid soluble sheet 112, impregnated with complementary feed substance 116. The upper and lower layers 124, 126 are integrally formed. The liquid soluble sheet 112 is formed as a single blank, the plurality of seeds 114 are placed in the required predetermined spaced relationship over half of the liquid soluble sheet 112, and the liquid soluble sheet 112 is then folded over onto itself, trapping the seeds 114 in position between the now formed upper and lower layers 124, 126. The adjacent perimeter edges 128 of the liquid soluble sheet 112 are connected together, for example by heat sealing, to prevent separation of the layers and thus undesirable release of the seeds 114.
Turning now to Figure 6, a third embodiment of a seed planting and nutrition device 210 is shown. This device again corresponds closely to the first embodiment described above, and the various modifications mentioned previously are also applicable. As such, similar numbers again refer to similar parts, and further detailed
description is omitted.
This embodiment differs only from the second embodiment in that upper and lower layers 224, 226 of the liquid soluble sheet 212, again impregnated with the complementary feed substance 216, are formed separately. A plurality of seeds 214 are positioned in predetermined spaced relationship on the lower layer, and the upper layer is superposed on the lower layer. The adjacent perimeter edges 228 are again connected, such as by heat sealing, to prevent untimely release of the seeds 214.
In the second and third embodiments, further welding can take place on or across the liquid soluble sheet and between adjacent seeds to prevent undesirable movement of the seeds between the upper and lower layers.
Although a liquid soluble sheet has been referred to, obviously a strip can be used. It is also envisaged that bulkier liquid soluble elements can be used, instead of the sheet or strip. Such a bulkier liquid soluble element might be in the form of a cylindrical roll, or a thick pad. In this case, the liquid soluble element can have multiple layers, so that a plurality of layers of seeds, still in spaced relationship, are provided. The seeds can thus adopt a three dimensional arrangement.
The liquid soluble element can include other substances, in addition to the feed substance, such as weed killer, thus providing localised and targeted removal of weeds as the seeds grow.
Although it is suggested that the feed substance and any other substance is mixed in during the production of the water soluble element, it is feasible that such substances can be, alternatively or additionally, provided on a surface of the water soluble element.
The liquid soluble element is cuttable to allow shaping and specific sizing by a user.
It is thus possible to provide a seed planting and nutrition device which is simple and cost-effective to produce, easy to implement without requiring intricate and specialised agricultural machinery, and which significantly reduces labour time. It is also possible to do away with a separate procedure of applying a feed substance to encourage growth of the seeds. The feed substance is targeted and localised, thus reducing wastage.
The embodiments described above are given by way of examples only, and various other modifications will be apparent to persons skilled in the art without departing from the scope of the invention, as defmed by the appended claims.
