Description

The invention relates to a soil and plant additive.

Soil improvers are substances that influence the soil biotically, chemically or physically in order to improve its condition (crumb stability, pore volume, water retention, etc.).

Plant aids are designed to act on the plant to support the growth and health of the plant.

The problem is the lack of combinatorial effect with other soil or plant additives used in parallel.

Another problem with previous soil and plant additives is that they are administered in the form of powder, chips or solution, which is inadequate for many applications. As a powder, the additives are easily blown away after or during formation or are quickly washed out by heavy watering or rain.

However, due to their structure, chips have to be worked into the soil with great effort in order to have a sufficient effect. Once they have been worked in, they cannot have an immediate effect, but require a considerable amount of time due to the necessary conversion of the active ingredient in the soil.

The dosage form as a solution or fluid is not advantageous for transport-economic and work-technical reasons.

The invention, however, is based on the task of providing a universal and sustainable improvement and recovery of the physical and biochemical soil quality and of creating optimal growth conditions for plants by providing all necessary trace elements and nutrients that are directly available to plants.

According to the invention, this is achieved by a soil and plant auxiliary agent having the features of claim 1.

The subclaims give advantageous embodiments of the plant auxiliary agent.

It is particularly advantageous that the selected combination of two types of algae provides trace elements, amino acids, proteins, easily plant-available carbohydrates, growth hormones, vitamins, polyuronic acids and alginates in an optimal proportion for soil and plant.

Not only will the crops and ornamental plants find optimal conditions, but the sustainable improvement of the soil (structure, pH value, trace element supply and thus improved nutrient uptake by the plants) will also activate soil life and stimulate natural conversion processes. Excess and harmful soil acids that inhibit growth are neutralized.

At the same time, the addition of the brown algae Ascophyllum nodosum introduces an optimal amount of organic polyuronic acids into the soil, which bind trace elements and enable the formation of valuable clay-humus complexes. These in turn will promote the crumbly structure of the soil, which is crucial for soil aeration and water retention capacity. The formation of a crumbly soil structure is further promoted by the structure of the ground skeletons of the red algae Lithothamnion calcareum. The macroscopic structures serve to loosen the soil and at the same time the algae structures will still be able to absorb water, thus increasing the water retention capacity of the soil.

The components contained in brown algae (especially those harvested in colder waters), such as easily plant-available carbohydrates, vitamins

mine, hormones, trace elements and alginates, a plant-strengthening effect is achieved, especially in stressful situations (&zgr;. &Bgr;. drought, fungal infestation, viral infection, pest insect infestation, etc.) and phytosanitary effect.

In order to preserve the valuable micro and macro nutrients, and in particular amino acids and vitamins, during the production of dust-free granules, these must be dried gently at low temperatures. A maximum heating of 35 ⁰ C has proven to be effective.

The problem of dust-free application of the soil and plant additive can also be solved elegantly by granulation using the proposed combination of two different types of algae. By adding a small amount of a natural binding agent and water, a dust-free, transport-stable granulate can be produced that dissolves easily again when water is added.

A grain size of one to four millimeters is particularly suggested, with the smaller size being suitable for use in hobby gardens, while the larger size can be used in agriculture. By dissolving it in water beforehand, the plant aid can also be introduced into the soil in liquid form, particularly when used in allotment gardens.

Further features and advantages of the invention emerge from the following description of a preferred example of the production of the soil and plant additive.

f ÖSiMERST A B£fEHMgRT·

Advantageously, calcareous algae such as Lithothamnion calcareum are freshly harvested from clean regions of the Atlantic, for example the waters of the French Atlantic coast, and then dried particularly gently and ground extremely gently without heating using a ball mill.

The brown algae are harvested from certain water regions of the North Sea, which are particularly low in pollutants and cool, and are dried on land and carefully ground.

The two finely ground algae are then granulated with the addition of water and a natural binding agent and dried at the lowest temperatures, bagged and offered to the consumer.

The predominant component of the soil and plant additive is the red algae Lithothamnium calcareum. Its proportion is between approx. 70% and 95%, depending on the nutrient content it contains, preferably 80%. Thanks to the gentle and fine grinding (90% of the algae material is smaller than 160μπα), the valuable red algae ingredients can fully develop their positive properties (trace element supply, especially iodine and selenium, pH regulation, structural improvement) after the granulate has dissolved.

The brown algae Ascophyllum nodosum, with its easily plant-available carbohydrates, vitamins and organic polyuronic acids as well as many trace elements, is contained in soil and plant additives at around 5% to 20%, but usually 20%. The valuable ingredients of the brown algae include, among other things:

Root formation, cell structure and thus plant growth and health are promoted, but also root mykhorrhiza is improved.

The particularly nutritious brown algae make it possible to sustainably promote the natural resistance of plants in stressful situations (e.g. drought) and against fungal infestation, viral infections and pests. The brown algae also have very high iodine contents, which lead to an optimal iodine supply to the soil and thus to the plants and ultimately also benefits people.

It should also be emphasized that the combination of both types of algae ensures an excellent supply of selenium to the soil and plants. Other important trace elements in order of frequency are iron, sulfur, manganese, zinc, boron, fluorine, copper, nickel, molybdenum, cobalt and indium.

In this combination, the trace elements present in their natural form create optimal growth and development conditions for plants. At the same time, a sustainable improvement in the health of the soil and an increase in soil fertility is achieved. The dissolved granules improve the crumb structure and the formation of the clay-humus complexes, which in turn increases their water retention capacity.

Compared to crystalline fertilizers, the soil and plant additive according to the invention is also characterized by its easier dosing as a granulate, its improved ability to penetrate into the soil and its optimal influence on the soil environment.
