Abstract
Abstract A plant marker which serves not only to facilitate the implant of seeds at the proper depth, but also functioning to encourage the upward growth of the seedlings. The marker is constituted by a tab which is insertable in soil to a depth determined by a ground line which divides the front face of the tab into a short lower section and a longer upper section. Mounted across the lower section is a piece of bio-degradable tape encapsulating the seeds to be planted. The upper section is coated with a light-reflecting layer whereby when the marker is buried in soil, the resultant seedlings will intercept the rays of the sun advancing toward the upper section and will be directly exposed to incident rays on one side, the other side of the seedlings being exposed to reflected radiation, whereby the seedlings will not elongate and incline toward the source of the rays but will grow upwardly.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
154 words
A seed-bearing marker comprising a tab having a ground line on the front face thereof at a level appropriate to the type of seed being sown, the ground line dividing the front face into a short lower section insertable into the soil and a longer upper section above the soil, a piece of biodegradable tape extending across the lower section parallel to the line, said tape encapsulating a charge of seed, the ends of said tape being mechanically latched to said tab, there by avoiding the presence of chemical bonding agents that might react unfavorably with the seeds or the soil, said upper face having a highly reflective layer thereon whereby incident light is reflected by this layer, and seedlings emerging from the seed are exposed both to incident light and to reflected radiation to a degree whereby the seedlings will not elongate and incline toward the source of light but will grow upwardly.
Claim 2
Dependent Claim
154 words
A seed-bearing marker comprising a tab having a ground line on the front face thereof at a level appropriate to the type of seed being sown, the ground line dividing the front face into a short lower section insertable into the soil and a longer upper section above the soil, a piece of biodegradable tape extending across the lower section parallel to the line, said tape encapsulating a charge of seed, the ends of said tape being mechanically latched to said tab, there by avoiding the presence of chemical bonding agents that might react unfavorably with the seeds or the soil, said upper face having a highly reflective layer thereon whereby incident light is reflected by this layer, and seedlings emerging from the seed are exposed both to incident light and to reflected radiation to a degree whereby the seedlings will not elongate and incline toward the source of light but will grow upwardly.
Claim 3
Dependent Claim
43 words
A marker as set forth in claim 1, wherein said tab is provided with a pair of angled slits cut into the opposing edges thereof, the ends of the tape piece being forced into said slits to secure the piece to the tab.
Claim 4
Dependent Claim
35 words
A marker as set forth in claim 1, wherein said tab is provided with a pair of parallel notches into which the ends of the piece are forced to secure the piece to the tab.
Claim 5
Dependent Claim
18 words
A marker as set forth in claim 1, wherein the tape piece is formed of water-soluble polyethylene oxide.
Claim 6
Dependent Claim
19 words
A marker as set forth in claim 4, wherein said polyethylene oxide is intermingled with a water-soluble plant nutrient.
Claim 7
Dependent Claim
28 words
A marker as set forth in claim 1, wherein the reverse face of the tab carries an illustration of the type of plant which emerges from the seeds.
Claim 8
Dependent Claim
22 words
A marker as set forth in claim 1, wherein said layer is formed from a metal foil laminated to said upper section.
Claim 9
Dependent Claim
36 words
A marker as set forth in claim 7, wherein said foil is aluminum which serves not only to reflect the rays but also to absorb heat therefrom and to radiate the heat to warm the seedling.
Claim 10
Dependent Claim
17 words
A marker as set forth in claim 1, wherein said lower section is pointed to facilitate insertion.
Claim 11
Dependent Claim
16 words
A marker as set forth in claim 1, wherein said tab is formed of moisture-resistant cardboard.
Claim 12
Dependent Claim
17 words
A marker as set forth in claim 1 wherein said tape piece is formed of polyvinyl alcohol.
Claim 13
Dependent Claim
24 words
A marker as set forth in claim 1, wherein said tab is curved to form a concave reflector to concentrate rays on the seedling.
Claim 14
Dependent Claim
19 words
A marker as set forth in claim 1, wherein the ends of the tape are stapled to said tab.
