Definitions
- the invention relates to a seed unit (1), which has at least one seed (2), a layer (3), for example made of vegetable charcoal, and a polymer superabsorbent (5), such as a cross-linked acrylamide/acrylic acid copolymer potassium salt, and optionally a shell (9) and further auxiliaries, the polymeric superabsorber (5) optionally having a grain size of 50 gm-400 gm and serving not only as a water reservoir but also as a disintegrant element.
- a seed unit (1) which has at least one seed (2), a layer (3), for example made of vegetable charcoal, and a polymer superabsorbent (5), such as a cross-linked acrylamide/acrylic acid copolymer potassium salt, and optionally a shell (9) and further auxiliaries, the polymeric superabsorber (5) optionally having a grain size of 50 gm-400 gm and serving not only as a water reservoir but also as a disintegrant element.
- the EU Commission is reducing the number of approved herbicides, insecticides and fungicides by allowing their approvals to expire, not allowing any new agents and limiting the use of approved agents. Their goal is to better protect both people and the environment from the toxins used. At the same time, however, conventional agriculture lacks alternatives to protect its crops, which means that exemptions are repeatedly granted to protect farmers from crop failures.
- the pelleting mass contains crop protection agents adapted to the crop. This means that they are applied in a very targeted manner and only in small quantities. In addition, the pelleting protects the plant particularly well in a particularly critical phase of growth - germination.
- Plant-specific nutrients can be added to the pelleting mass. Here, too, the addition is particularly targeted.
- CN109168409A describes a seed lubricant in which vegetable charcoal is mixed with a humectant made from potassium and sodium acrylate.
- the humectant made of potassium and sodium acrylate is ground very finely (“1000 to 1500 meshes”) and can therefore not be used as a disintegrant.
- JPH09248017A describes a coated rice seed in which, for example, polyacrylic resin is applied to the seed surface and, for example, activated carbon powder is added.
- the polyacrylate resin is used for caking/adhering and not in particulate form.
- the German translation of European patent specification EP 1 091 641 B1 describes a substrate additive as pourable granules with a grain size of 0.3 to 3.0 mm for use in germination units.
- the substrate additive comprises various substances, including superabsorbent polymers (SAP, with Stockosorb® being used in the examples) and fillers such as vermiculite, wood fibers or mineral fibers, with polyethylene glycol and polyvinyl alcohol being mentioned as binders.
- SAP superabsorbent polymers
- fillers such as vermiculite, wood fibers or mineral fibers
- polyethylene glycol and polyvinyl alcohol being mentioned as binders.
- no pellet is formed around the seed and the superabsorbent polymer is placed directly in the soil and only serves as a water reservoir and not (also) as an explosive.
- EP 373 348 A1 describes a substrate additive containing a porous ion exchange material and a porous mineral additive, as well as charcoal/activated carbon and polyacrylamide. However, once again no pellet is formed around the seed and the polyacrylamide is introduced at the plant root and serves there only as a water reservoir and not (also) as a disintegrant
- WO2004/036975 A1 describes a method for producing a pellet in which peat has been mixed with an insecticide, for example, and in which a seed is introduced into the dried mixture through a hole. Apart from the fact that, in contrast to biochar, the peat has an acidic pH, no superabsorbent is used here either.

- the polymeric super absorber preferably has a grain size of 50 ⁇ m-400 ⁇ m, particularly when the polymeric super absorber is a polyacrylamide, a crosslinked arylamide/acrylic acid, a polyacrylate or an acrylamide/acrylic acid copolymer.
- this seed unit has the advantage that - especially when the seed unit takes the form of a pellet or a pile, or since the layer at least partially and in particular completely encloses the seed - the combination with the polymeric superabsorbent this layer / the Pellet/pill breaks open to facilitate seed/seedling propagation after seed planting.
- the surprising germination success of the seed unit according to the invention is based on the fact that the polymeric superabsorber, which was only considered as a water reservoir, can expand enormously when absorbing water and thus the layer/the pellet/the pill can break open.
- the polymeric superabsorbent should possibly have a certain particle size, which must not be selected too large or too small in order to achieve this effect.
- the dimension/grain size of the material of the layer should not be too small, so that the layer around the seed (especially if it consists of several partial layers building on top of each other) does not become too firm, making it difficult to break open.
- the dimension (e.g. the grain size) of the material should not be too large, otherwise an even coating of the seed, especially with several thin partial layers, becomes more difficult purely due to the dimensions of the material.
