Abstract

PRESEEDED CARPET AND METHOD OF MAKING SAME

ABSTRACT

A novel seed carrier for planting grass or other plants, which aids in the prevention of erosion and the improvement and protection of topsoil is disclosed. The method of making such a seed carrier is also disclosed. Prior seed carriers utilize a non-nutritive adhesive or glue to secure the seeds to the flexible seed-carrying sheet or mat. A layer of fertilizer to provide nutrient for the germinating seeds might also be bound separately to the prior seed carriers. The present invention utilizes a starch mixture to act both as an adhesive and seed nutrient. The preseeded carpet may be inexpensively and effectively prepared using one or two layers of a burlap material as the seed carrying medium, to which a starch paste and seed mixture may be applied. A mixture of crushed and whole seed utilized with the starch paste provides superior growth.

Description

~15~Z7 PRESEEDED CARPET AND METHOD OF MAKING SAME

This invention relates to preseeded sheets or mats for the planting of grass or other plants, the prevention of erosion and soil enrichment. More particularly, the invention relates to a woven biodegradable seed carrier utilizing a nutrient seed adhesive.
Various seed carriers are known whereby grass seed or other plant seed may be secured to a flexible medium of paper, woven material, netting or compressed organic matter. Such seed carriers may be unrolled or otherwise spread upon the ground to facilitate the planting of grass or other plants.
Such a method has a number of advantages over conventional seed planting methods. It allows a uniform distribution of seed and may avoid the eating of the seeds by small animals or birds.
Primarily, it allows the planting of a grass cover on otherwise inhospitable soil. Such method permits the planting of grass on steep hillsides where erosion would otherwise carry seeds away. It also permits the planting of grass and creation of a topsoil layer where the soil conditions would otherwise be inadequate for plant growth. The use of seed carriers permits fertilizer and a supporting medium to be laid in one operation with the grass or other seed.
Conventional seed carriers have typically consisted of a flexible sheet of woven or unwoven material to which the seed may be secured by an adhesive. In addition, there is generally included a fertilizer layer also adhered to the seed carrier.

For example, United States patent No. 1,971,504 issued to Pratt discloses a seed carrier consisting of paper or paper reinforced with threads to which is adhered a layer of water soluble fertilizer. The fertilizer layer i5 separated from the seeds by a breaker strip of plastic material. The seeds are adhered to the breaker strip by an adhesive such as gelatin or glue. A similar seed carrier or mat is disclosed in Canadian patent No. 1,072,740 issued to Muldner. This seed mat again consists of a base sheet which in this case consists of tissue paper. An adhesive binder comprising a water-based rubber adhesive compound is applied to the base sheet, to which a layer of seeds and compressed peat particles is applied. A
further layer of adhesive is then applied to the mat, and finally a fibrous veil is applied to this last layer to retain the integrity of the mat when wet. Such seed mats or carriers, however, have proven too expensive to find wide acceptance.
The present invention provides a more practical and inexpensive seed carrier through use of a starch-based adhesive for adhering the seed to the seed-carrying medium, which adhesive may also act as the plant nutrient. The invention comprises a flexible, woven, bio-degradable seed-carrying medium, which in one embodiment may be burlap, to which the seeds, such as grass seed, may be adhered using a starch-based adhesive. To improve the nutrient qualities of the adhesive medium, crushed seeds, whether of the type being planted or of different varieties, such as soya beans, may be added to the starch and seed adhesive mixture. Where additional warmth or protection of the seeds is required, particularly on agricultural land or where the ground is particularly inhospitable, two layers of the seed-carrying medium may be used to sandwich the adhesive starch and combined seed mixture.

I~
.. ; . . .
, ' ~ ' , ' : ' ,' The invention is also directed to a method of preparing such a seed carrier, which comprises the steps of cutting a section of the seed-carrying medium, such as burlap, in the desired size and shape, mixing approximately equal parts of powdered starch and cold water, adding approximately ten parts of boiling water, cooling the mixture until it forms a gelatin, and then mixing into the gelatin two parts of seed of the desired variety, which may be a mixture of equal parts of whole and crushed seeds. The gelatinized starch and seed mixture is then brushed or otherwise applied to the seed-carrying medium and allowed to dry. Where two layers of the seed-carrying medium are used, a thicker layer of the adhesive/seed mixture may be applied. In this latter case, the preferred ratio of whole to crushed seed is 5:7 for optimum growth.
In this way, a simple and inexpensive seed carrier is provided with quaIities which are well-suited for the growth of the plants and development of soil. The starch-based adhesive has been found to provide a good source of nutrients for the growing plants, and the type of nutrients provided may be varied by utilizing different combinations of starches and crushed grains of different varieties, such as common wheat, rice or other grains. Alternatively, chemical or organic fertilizers may be added to the adhesive mixture.
In drawinys which illustrate embodiments of the invention, Figure 1 illustrates one embodiment of the invention in cross-section and Figure 2 illustrates a second embodiment of the invention in cross-section.
Looking first at Figure 1, there is illustrated in cross-section a single-layer preseeded carpet 1, according to ~151427 this invention. A suitable seed-carrying medium 2, is selected. The seed-carrying medium should be a flexible, bio-degradable medium. The flexibility permits the seed carpet to cling to the contours of the soil. The medium should be bio-degradable in order to permit the medium to disintegrate and form part of the topsoil. It has been found that a rough-woven burlap material, such as that used in potato sacks, is ideal for the purpose. Such a woven material has suitably spaced interstices which allow the required number of grass seeds to be carried within the surface of the seed-carrying medium. Those seeds which fall into such interstices are provided greater protection from birds and animals and wind or water erosion. The fineness of the weave in the burlap material can be varied according to the particular ground and soil condition or seed type. A further advantage of the use of burlap as the seed-carrying medium results from its relatively low cost as compared with the cost of construction of other seed carriers.
Other characteristics of the burlap medium have been found to make it ideally suited for use in the present invention. The relatively wide mesh of the material allows roots to easily penetrate into the soil below the seed carrier, thereby anchoring it to both prevent the underlying soil from being eroded and to prevent the seed carpet from being blown or washed away. Pegs, nails or other anchoring devices can also be used to secure the carpets to the underlying ground on particularly steep slopes. The relatively wide mesh of the burlap also allows the access of light and water to the germinating seed and the growing grass stalks easily attain the light and air above. Burlap also exhibits good moisture-.

~L51427 retaining and drainage characteristics. It readily retains moisture to act as a mulch to keep the germinating seeds moist.
This effect can be enhanced by the use of double layers of burlap as described below.
After selecting a seed-carrying medium of suitable characteristics, size and shape, the seed-carrying adhesive layer 3 is prepared. A powdered starch base is used.
Cornstarch has been found to be particularly suitable for growing grass. Potato starch or other starches may also be utilized for grass seed. Equal portions of the starch powder and cold water are first mixed. To this mixture is then added boiling water in the amount of about ten portions. This mixture is allowed to cool into a colourless gelatin. Two portions of the desired variety of seed which consists preferably of one portion of whole and one of crushed seed is then mixed into the gelatin. For purposes of prevention of soil erosion and generation of new topsoil, grass seed is the preferred variety. However, other varieties of seed, particularly grains, may be planted using the preseeded carpet.
To enhance the nutrient value of the adhesive mixture, crushed seed or grain is added to the mixture with the whole seed. Crushed seed of the same variety as the whole seed has been found to substantially improve the quality of plant produced. For example, where the carpet is preseeded with wheat, crushed wheat may be added to the adhesive mixture.
Similarly, crushed corn seed could be added to the adhesive mixture of cornstarch and whole cornseed. Crushed soybean, due to its high protein content, can produce a particularly good crop. The use of various types of starches and crushed seed as Il '~ ~

1~514Z7 the supporting medium for the selected variety of seed has also been found to produce particularly healthy plants. Chemical or organic fertilizer may also be added to the adhesive mixture (or the underlying soil prior to application of the carpet, although less than would otherwise be applied is required).
The seed and starch mixture is then simply brushed or otherwise applied to the burlap or other seed-carrying medium. The burlap is allowed to dry. It may then be rolled up for transportation or cut into tile-sized pieces.
To install the preseeded carpet, the carpet is merely unrolled or otherwise spread in the desired location. On steep slopes, the carpet may be secured using wooden pegs, cement nails or other means. The single layer of burlap will retain a certain amount of moisture, however ground water is able to drain easily through the carpet. As the seeds germinate, the roots are able to penetrate through to the ground below and anchor the carpet. Eventually, the burlap layer disintegrates, and a layer of soil develops. The carpet rolls may be unrolled by mechanized means, such as a tractor, and adjacent rolls may be fastened using appropriate means to unify the entire layer of carpet. Generally the carpet will be watered upon installation. Due to the ideal growing characteristics of the carpet, two crops of the type planted may be laid and grown in one growing season.
Figure 2 illustrates in cross-section a second embodiment of the invention 4 which utilizes a double layer of the burlap or other seed carrying material 5 and 6 to sandwich and protect the layer of seed-bearing adhesive mixture 7. In the preparation of this embodiment, the second layer of burlap material is spread on the initial layer prior to the drying ~5~27 step. Generally the layer of adhesive mixture will he applied more thickly in this embodiment. In this embodiment a ratio of whole to crushed seed of 5:7 in the mixture is preferred.
Chemical or organic fertilizer may again be added to layer 7.
The double-layer carpet is preferable in situations where the underlying ground conditions are particularly difficult or where highly erosive conditions of wind and rain are at work such as mountainous areas. The double-layer carpet also provides additional protection from animals and birds to the seeds. The double-layer carpet also more effectively retains water in dry conditions. The upper layer itself retains moisture in contact with the germinating seeds. The central layer of starch mixture will also provide some moisture for the seeds. The lower layer of burlap again soaks up moisture for the plant roots, and the soil in contact with the lower layer will remain moist for longer periods. The upper layer of the double-layered carpet may be secured to the lower layer by sewing or stitching the two layers together in a regular pattern, to provide a quilted pattern creatiny pockets of seeds and nutrient.
Due to the particularly suitable characteristics of the burlap material and the starch-based adhesive utilized in this invention, the preseeded carpet of this invention has been found to be ideally suited for prevention of erosion, protection of top soil, and generation of new soil and plant cover. Despite the improved characteristics of the preseeded carpet, the materials are of very low cost and consequently adapted for use on a large scale. While burlap has been found particularly suitable, other bio-deyradable seed-carryiny media may be used in the invention.
