Abstract

The invention relates to a fertilizer comprising elemental sulfur and a micronutrient fertilizer.

Description

Description: The invention relates to a fertilizer which contains elemental sulfur.

[0002] Sulfur has become almost completely meaningless as an air pollutant today. For growth, however, a plant also needs sulfur, which is only too little introduced into the arable land via the environment. However, if the plant does not have sufficient sulfur available, this leads to deficiency symptoms and metabolic disorders.

[0003] Sulfur is therefore becoming increasingly important as a nutrient element to be added via the fertilizer.

From DE 20 2015 105 252 U1 a fertilizer is known which, in addition to water-soluble sulfur, also contains elemental sulfur. In this way, plant-utilizable sulfur can be provided with a single fertilization from the beginning to the end of a vegetation period.

The water-soluble sulfur supplies the plant with sulfur until about the middle of the growing season. The water-soluble sulfur cannot stay in the soil and is washed out.

The elemental sulfur, however, provides sulfur from about two weeks after application until the end of the growing season. Elemental sulfur therefore supplies the plant with sulfur, even if the water-soluble sulfur originally present in the fertilizer has been used up or washed out. A renewed fertilization with water-soluble sulfur is not necessary. The plant is therefore supplied with sulfur throughout the growing season, with a single fertilization being sufficient.

The elemental sulfur can be converted to water-soluble sulfur. Elemental sulfur plays a central role in metabolic processes, especially energy metabolism, of some bacteria. Sulfur-oxidizing bacteria oxidize the elemental sulfur to sulfur sulfate. Many of these microorganisms can store elemental sulfur in the form of spheres intracellularly and as a reserve for periods of scarce sulfur supply. Once the elemental sulfur has been converted into water-soluble sulfur, it can be easily absorbed and reused by the plant.

[0008] The non-water-soluble elemental sulfur initially forms a stock of sulfur in the soil, which is not washed out. The elemental sulfur is only gradually converted into the water-soluble sulfur and taken up directly by the plant, so that wash-out is at least substantially prevented.

[0009] In DE 20 2015 105 252 U1, a urea fertilizer with nitrification inhibitor is used as stabilized nitrogen. This works safely and regardless of the weather, so that the plant is protected from leaching even after high fertilization after fertilization.

Plants only require micronutrients in small amounts. However, these are important for the function and structure of ferments and enzymes, for example. Different micronutrients should therefore be available for the plants.

Dryness and the pH value can impair the uptake of plant-available micronutrients from the soil. Manganese, boron, zinc and copper, for example, are poorly available at high pH values, while molybdenum can only be inadequately absorbed by the plant at low pH values.

So far, micronutrients have been sprayed onto the field, especially in liquid form. This requires an additional step.

It is therefore an object of the invention to provide a multifunctional fertilizer with which one step can be saved.

Patent Office [0014] This object is achieved by a fertilizer with the features of the independent claim.

[0015] According to the invention, the fertilizer comprises elemental sulfur, that is to say sulfur with the zero oxidation state (SO). The elemental sulfur is particularly water-insoluble and is therefore not washed out.

[0016] The fertilizer may comprise an elemental sulfur fertilizer containing the elemental sulfur. The average grain diameter of the elemental sulfur fertilizer can be between approximately 2 mm and 4 mm.

[0017] The elemental sulfur fertilizer can consist exclusively of elemental sulfur or comprise further additives.

[0018] For example, the elemental sulfur fertilizer can comprise between 85% and 95%, in particular 90%, elemental sulfur.

A granulated elemental sulfur fertilizer with 90% elemental sulfur is e.g. known as Sulfogran ® 90 or Wigor ® S on the market. The elemental sulfur fertilizers differ, for example, in the fineness of grinding and the availability for microorganisms.

The fertilizer is for agriculture, especially for plants such as corn, potatoes, lettuce, crucifers such as Rapeseed, cabbage or the like are suitable. The fertilizer is also advantageous for cereals because the sulfur is the number of grains, i.e. fertility, as well as the baking quality, e.g. measured by the sedimentation value, favorably influenced.

[0021] According to the invention, the fertilizer has a micronutrient fertilizer.

In addition to elemental sulfur and a micronutrient fertilizer, the fertilizer can also have other components, e.g. a lime nitrogen fertilizer. Alternatively, the fertilizer can consist only of elemental sulfur and a micronutrient fertilizer.

The fertilizer is multifunctional because it supplies the soil with various important nutrients.

According to the invention, the micronutrients can form part of the fertilizer and be discharged into the field together with other fertilizer components.

In this way, an additional step can be saved, thereby reducing costs.

The micronutrient fertilizer can be in the form of granules and can therefore be mixed well with other components of the fertilizer.

Developments of the invention can also be found in the dependent claims and the description.

[0028] According to one embodiment, the micronutrient fertilizer comprises boron, zinc, manganese, selenium, cobalt, molybdenum, copper and / or iron. The plant can thus be adequately supplied with one or more different micronutrients.

If there is a lack of boron, the plant stops developing, for example, and grows slowly. Boron can be used, for example, in fertilizers for vegetables, e.g. Potatoes, rapeseed, corn and / or soy can be added.

[0030] Zinc and copper have a positive influence on the vitality and stability of a plant. Zinc is essential for plant growth and for various metabolic processes. Zinc is also important for fertility, the immune system and the digestion of animals fed with plants.

[0031] Copper is important for the blood and bone formation of animals fed with the plants.

Manganese supports the plant in photosynthesis and promotes root development

development.

[0033] A lack of selenium can lead to diseases in humans and animals, for example to arrhythmias, heart failure, pulmonary edema, fertility problems and / or thyroid inflammation. Selenium is primarily consumed by humans through animal foods, since plant foods contain relatively little selenium. Fertilization with selenium can also significantly increase its share in plant foods.

Selenium can also be used in fertilizers for meadows and pastures in order to feed the animals fed with them, e.g. Cattle and / or horses to be supplied with selenium.

[0035] Selenium is also bio-suitable.

Cobalt is an important component of vitamin B12 and enzymes. A deficiency leads to reproductive disorders in animals fed with the plants.

Molybdenum is important for various metabolic functions and the nitrogen utilization of the plant.

[0038] According to a further embodiment, the micronutrient fertilizer comprises magnesium, calcium, sodium and / or sulfur. The plant can thus be adequately supplied with different nutrients.

EXCELLO ® 331 is known on the market, for example. This micronutrient fertilizer contains 3.0% manganese, 3.0% zinc, 1.0% boron, 11.8% magnesium oxide, 29.3% calcium oxide, 0.005% water-soluble molybdenum and 0.003% cobalt.

In addition, e.g. Excello ® willow known. This micronutrient fertilizer includes 2.0% iron, 1.5% zinc, 1.0% manganese, 0.5% copper, 15.0% sodium chloride, 3.0% sulfur, 0.003% cobalt, 0.006% selenium, 7 , 9% magnesium oxide and 25.0% calcium oxide.

In addition, granular N and P (GNP) fertilizers are known from ICL Fertilizers, for example. For example, this micronutrient fertilizer can have a composition of 11.5% nitrogen, 2.5% phosphorus and 2.2% boron. A higher proportion of phosphorus, e.g. 5.5% is possible.

In addition, sulfur, for example with a share of 15%, can also be provided. This results in a micronutrient fertilizer with 11.5% nitrogen, 5.5% phosphorus, 15% sulfur and 2.2% boron.

According to a further embodiment, the proportion of the micronutrient fertilizer in the fertilizer is between 1% and 15%, in particular between 3% and 10%, preferably 7

%.

According to a further embodiment, the fertilizer has a lime nitrogen fertilizer. Calcium cyanamide is also called calcium cyanamide (CaCN2). This is a stabilized fertilizer. The lime nitrogen fertilizer can comprise or consist of nitrate nitrogen, cyanamide nitrogen, dicyandiamide nitrogen and / or lime.

Lime is an important part of a healthy soil. Due to the increasingly tight crop rotations, fertilization with lime is important to ensure high quality of the plants and high yields.

Up to now, the soil has to be additionally fertilized with lime. This requires an additional step. The fertilizer according to the invention, on the other hand, can already have a lime nitrogen fertilizer, so that an additional work step is not required.

In addition to elemental sulfur, the micronutrient fertilizer and a lime nitrogen fertilizer, the fertilizer can also have other components. Alternatively, the fertilizer can e.g. consist only of elemental sulfur, the micronutrient fertilizer and a lime nitrogen fertilizer.

AT15 971 U1 2018-10-15 Austrian

Patentamt [0048] The fertilizer is multifunctional because it provides the soil with various important nutrients.

In particular, the lime nitrogen fertilizer contains between 15% and 25%, preferably 19.8%, nitrogen. The proportion of nitrate nitrogen can be between 1% and 3%, preferably 1.8%. The proportion of cyanamide nitrogen can be at least 10%, preferably at least 15%, while the proportion of dicyandiamide nitrogen can be about 0.5%. The lime content (CaO) can be at least 40%, preferably at least 50%.

A lime nitrogen fertilizer with a nitrogen content of 19.8% and a lime content of at least 50% is also known on the market as PERLKA ®.

The lime nitrogen fertilizer can be in the form of granules. The average grain diameter can be between about 0.8 and 3.5 mm. Furthermore, it is environmentally friendly and can be used for various purposes.

Plants are supplied with nitrogen while lime is added to the soil. Calcium cyanamide increases the microbiological activity in the soil.

According to a further embodiment, the fertilizer comprises water-soluble sulfur, in particular sulfur sulfate or sulfur trioxide.

Water-soluble sulfur has the advantage that the sulfur can be readily absorbed by the plant in this form. A previous conversion, e.g. by microorganisms, is not necessary. The water-soluble sulfur is available to the plant for consumption immediately after fertilizing.

According to a further embodiment, the fertilizer comprises a nitrogen fertilizer, a magnesium fertilizer, a phosphate fertilizer, a potash fertilizer and / or a phosphate-potash fertilizer.

In particular, according to the invention, a nitrogen fertilizer, which is also known as N fertilizer, can be combined with an elemental sulfur fertilizer and a calcium cyan nitrogen fertilizer or micronutrient fertilizer. However, a nitrogen fertilizer is not absolutely necessary. For example, the nitrogen can also be supplied via liquid manure.

Since sulfur, like nitrogen, is a central building block in proteins and is also responsible for the nitrate reductase in the plant, the nitrogen can no longer be used by the plant in the case of a sulfur deficiency. In order to be able to ensure efficient nitrogen fertilization, it is advantageous to combine it with sulfur fertilization that meets the needs.

The nitrogen fertilizer can only comprise nitrogen or additives. The average grain diameter of the nitrogen fertilizer can be between approximately 2 mm and 4 mm.

Preferably, the nitrogen fertilizer has water-soluble sulfur. By combining such a nitrogen fertilizer with an elemental sulfur fertilizer, both water-soluble sulfur and the elemental sulfur can be provided.

According to a further embodiment, the nitrogen fertilizer comprises sulfuric ammonia (SSA) or consists thereof. Sulfuric acid ammonia contains ammonium nitrogen, which e.g. less leaching compared to nitrate nitrogen. The fertilizer according to the invention can thus comprise or consist of sulfuric acid ammonia, elemental sulfur and a lime nitrogen fertilizer or a micronutrient fertilizer.

According to a further embodiment, the sulfuric acid ammonia comprises between 19% and 23%, in particular 21%, ammonium nitrogen and between 22% and 26%, in particular 24%, water-soluble sulfur. These are typical values for sulfuric acid ammonia.

According to a further embodiment, the nitrogen fertilizer comprises ammonium sulfate 4/12

AT15 971 U1 2018-10-15 Austrian

Patent Office

Urea or it consists of it. This leads to a good fertilizing effect and increases the yield. The fertilizer according to the invention can thus comprise or consist of ammonium sulfate urea, elemental sulfur and a calcium cyan nitrogen fertilizer or a micronutrient fertilizer.

Preferably, the ammonium sulfate urea comprises between 31% and 35%, especially 33%, total nitrogen and between 10% and 14%, especially 12%, water-soluble sulfur.

The ammonium sulfate urea can comprise between 20% and 24%, in particular 22.6%, carbamide nitrogen and between 8% and 12%, in particular 10.4%, ammonium nitrogen. A composition of 22.6% carbamide nitrogen and 10.4% ammonium nitrogen gives the 33% total nitrogen. Such ammonium sulfate urea with 12% water-soluble sulfur is also known as Piammon ®.

As an alternative or in addition to a nitrogen fertilizer, the fertilizer can also comprise a magnesium fertilizer. The magnesium fertilizer can only comprise magnesium or have additives.

[0066] In particular, the magnesium fertilizer has water-soluble sulfur. By combining such a magnesium fertilizer with an elemental sulfur fertilizer, both water-soluble sulfur and the elemental sulfur can thus be provided.

According to a further embodiment, the magnesium fertilizer comprises between 15% and 30%, in particular 25%, magnesium oxide and between 10% and 25%, in particular 20%, water-soluble sulfur. Such a magnesium fertilizer with 25% water-soluble magnesium oxide and 20% water-soluble sulfur is also known as kieserite. Kieserite is bio-suitable.

The proportion of kieserite in the fertilizer can be between 5% and 25%, in particular between 10% and 22%.

As an alternative or in addition to a nitrogen fertilizer or magnesium fertilizer, the fertilizer can also comprise a phosphate fertilizer. The phosphate fertilizer can only comprise phosphate or have additives.

[0070] Phosphate plays a central role in the metabolism of plants.

The phosphate fertilizer can have water-soluble sulfur. By combining such a phosphate fertilizer with an elemental sulfur fertilizer, both water-soluble sulfur and the elemental sulfur can thus be provided.

According to a further embodiment, the phosphate fertilizer comprises between 3% and 15%, in particular 9%, water-soluble sulfur.

As an alternative or in addition to a nitrogen fertilizer, magnesium fertilizer or phosphate fertilizer, the fertilizer can also comprise a potash fertilizer. The potash fertilizer can only comprise potassium or have additives.

[0074] In particular, the potash fertilizer has water-soluble sulfur. By combining such a potash fertilizer with an elemental sulfur fertilizer, both water-soluble sulfur and the elemental sulfur can thus be provided.

According to a further embodiment, the potash fertilizer comprises between 3% and 25%, in particular between 10% and 20%, preferably 12.5% or 17%, of water-soluble sulfur.

A potash fertilizer with 40% potassium oxide and 12.5% sulfur trioxide or 4% water-soluble sulfur is also known as Korn-Kali ®.

A potash fertilizer can also have, for example, 50% potassium and 17% sulfate.

5/12

AT15 971 U1 2018-10-15 Austrian

Patent Office [0078] The proportion of potash fertilizer in the fertilizer, if any, can be between 25% and 50%, in particular between 30% and 45%, preferably 38%.

In particular, the potash fertilizer is chloride-free or contains a maximum of 1% chloride. The Kali fertilizer is therefore free of chloride or only contains traces of it. Potassium can thus also be provided for plants sensitive to chloride, for example vegetables, in particular potatoes.

The potash fertilizer can have, for example, between 40% and 60%, preferably 50%, K2O and between 35% and 55%, preferably 45%, SO3.

A potash fertilizer with 50% K2O and 45% SO3 is also known as KALISOP ® in the market and for example for vegetables, e.g. Potatoes, suitable.

The fertilizer can comprise, for example, water-soluble sulfur, elemental sulfur, sea lime and KALISOP ®. Stabilized nitrogen may also be present in the fertilizer.

In particular, the potash fertilizer can be present as granules. It can therefore be mixed well with other components of the fertilizer.

Preferably, the potash fertilizer is completely water soluble so that the nutrients potassium and sulfur are immediately available to the plant.

As an alternative or in addition to a nitrogen fertilizer, magnesium fertilizer, phosphate fertilizer or potash fertilizer, the fertilizer can also comprise a phosphate potash fertilizer. [0086] In particular, the phosphate-potassium fertilizer has water-soluble sulfur.

By combining such a phosphate-potassium fertilizer with an elemental sulfur fertilizer, both water-soluble sulfur and the elemental sulfur can thus be provided.

According to a further embodiment, the phosphate potash fertilizer comprises between 1% and 10%, preferably 4%, of water-soluble sulfur. In particular, the phosphate-potassium fertilizer can have a proportion of between 5% and 15%, preferably 7.5%, of phosphorus. The proportion of potassium can be between 30% and 50%, preferably 40%. Calcium oxide can also be present, in particular in a proportion between 5% and 20%, preferably 10.8%.

A phosphate-potassium fertilizer can have, for example, 7.5% phosphorus, 40% potassium, 4% sulfate and 10.8% calcium oxide.

The proportion of phosphate-potassium fertilizer in the fertilizer - if any, can be between 20% and 40%.

According to a further embodiment, the fertilizer comprises bentonite. The bentonite can be contained, for example, in an elemental sulfur fertilizer which comprises the elemental sulfur. The proportion of bentonite in the elemental sulfur fertilizer can be between 5% and 15%, in particular 10%.

Bentonite forms e.g. Clay-humus complexes that stabilize the soil structure and increase soil fertility.

A granulated elemental sulfur fertilizer with 90% elemental sulfur and 10% bentonite is e.g. known as Schwedokal ® 90. Schwedokal ® 90 is bio-suitable.

The proportion of Schwedokal ® 90 in the fertilizer can be between 4% and 15%, in particular between 5% and 10%.

According to a further embodiment, the fertilizer comprises a urea fertilizer with nitrification inhibitor.

The grain diameter of the urea fertilizer can average between about 2 mm and 4

6/12

AT15 971 U1 2018-10-15 Austrian

Patent Office mm. In particular, a nitrogen, magnesium, phosphate, potash and / or phosphate-potash fertilizer can thus be combined according to the invention with an elemental sulfur fertilizer and a calcium cyanamide fertilizer or a micronutrient fertilizer and a urea fertilizer with nitrification inhibitor. The plant can be supplied with important nutrients through a single fertilization.

Like water-soluble sulfur, nitrate nitrogen cannot stay in the soil and is washed out.

With the urea fertilizer with nitrification inhibitor, however, the advantages of the ammonium form can be fully exploited. The urea is converted into ammonium nitrogen in a short time after application and reaching a certain soil temperature. The ammonium nitrogen is stabilized and its microbial conversion to nitrate is significantly delayed. In this way, a store of ammonium protected from relocation is created in the ground. Since plants can absorb ammonium just as well as nitrate, there is an ammonium-based diet that is controlled by plant growth as required. Higher amounts of nitrogen can be applied during fertilization without the risk of luxury consumption. Repeated fertilization is not necessary.

The fertilization is also simplified and can be made more variable, especially since stabilized nitrogen acts safely and regardless of the weather. Even with high rainfall after fertilization, it is thus protected from washing out.

A combination of a nitrogen fertilizer with an elemental sulfur fertilizer and a calcium cyan nitrogen fertilizer or a micronutrient fertilizer and a urea fertilizer with nitrification inhibitor thus makes it possible to provide stabilized nitrogen and a steady supply of sulfur during a complete growing season. Repeated fertilization is not necessary. The plant can grow from the beginning of are supplied with nitrogen, sulfur and lime or micronutrients for grain ripening in maize or rapeseed or until the ears are pushed in the grain.

According to a further embodiment, the urea fertilizer comprises 46% carbamide nitrogen. Such a urea fertilizer with nitrification inhibitor is also known as Alzon ® 46. In addition to or in addition to Perlka ®, Alzon ®, for example, can also be used as stabilizing nitrogen.

In particular, the proportion of urea fertilizer with nitrification inhibitor - if any - in the fertilizer between 5% and 50%, in particular between 10% and 40%, preferably 11.3%.

The nitrification inhibitor can comprise or consist of dicyandiamide, triazole, in particular 1,2,3 triazole or 1,2,4 triazole, allylthiourea and / or nitrapyrin. In particular, the nitrification inhibitor can be formed as a mixture of dicyandiamide and 1H-1,2,4 triazole.

[00104] These nitrification inhibitors have good inhibitory properties.

According to a further embodiment, the fertilizer comprises a diammonium phosphate fertilizer, in particular wherein the diammonium phosphate fertilizer comprises 18% nitrogen and 46% phosphorus and / or wherein the proportion of diammonium phosphate fertilizer in the fertilizer is between 15% and 60%, in particular between 16% and 24%, preferably 17.6%.

[00106] The diammonium phosphate fertilizer can be designed as (NH4) 2HPO4.

[00107] In particular, the diammonium phosphate (DAP) is present as granules. The average grain diameter can be between about 2 to 5 mm.

In particular, a nitrogen, magnesium, phosphate, potash and / or phosphate-potassium fertilizer with an elemental sulfur fertilizer and a calcium cyanamide fertilizer or a micronutrient fertilizer and a diammonium phosphate 7/12 can thus be used according to the invention

AT15 971 U1 2018-10-15 Austrian

Patent Office

Fertilizer can be combined. In addition, a lime nitrogen fertilizer and / or urea fertilizer with nitrification inhibitor can be provided.

The plant can be supplied with important nutrients by a single fertilization.

Preferably, at least part of the nitrogen is in ammonium form and is therefore not washed out. It also supports the absorption of phosphate and counteracts excessive absorption of potassium from the soil.

In particular, at least part of the phosphorus may also be in ammonium phosphate form, which is easier to assimilate for the soil.

According to a further embodiment, the fertilizer has a snail bait.

[00113] Snails can attack the plants as soon as they emerge. Accumulation is the time at which the plant seedlings emerge and grow out of the ground.

[00114] This point in time is particularly critical since the plant seedling can be very severely damaged, which ultimately leads to considerable crop losses. For example, small rapeseed plants can be attacked by snails.

[00115] Snail bait is therefore applied to the field. So far, this has been done regardless of the fertilization of the field.

[00116] According to the invention, the snail bait can be designed as granules, in particular snail grain. The snail bait can thus form part of the fertilizer and be carried away with it. An additional step to bring out the snail bait is therefore not necessary, which can reduce costs. Preferably the fertilizer is applied in late summer or autumn, e.g. held in August.

Mixtures in which a fertilizer is provided with snail bait are not yet known since, above all, the exact metering proves to be complex. On the one hand, the proportion of snail bait should be kept as low as possible due to the comparatively high costs. On the other hand, the proportion must be high enough to ensure noticeable protection against snails.

It was surprising that an effective fertilizer can be mixed by means of a metering mixer, which enables optimal protection against snails while avoiding unnecessary costs for excess snail bait.

According to a further embodiment, the proportion of snail bait in the fertilizer - if present at all - is between 1% and 6%, in particular between 3% and 4%, preferably 3.7%. The plants can thus be protected from snails without using an unnecessary amount of snail bait.

If, for example, 150 kg of fertilizer is applied per hectare, around 2 to 8 kg, e.g. 5 kg, snail bait may be included.

By means of a metering mixer, it is possible to add exactly the desired proportion of snail bait.

According to a further embodiment, the snail bait comprises metaldehyde, iron III phosphate and / or methiocarb.

[00123] The snail bait can have, for example, 2 to 5 grams per kilogram of metaldehyde.

A snail bait with 3 g / kg metaldehyde is e.g. known as Spiess-Urania ® G2 in the market. A snail bait with 4 g / kg metaldehyde is available as METAREX IN-OV ®. [00125] Furthermore, the snail bait can, for example, 5 to 15 grams per kilogram of Ei8 / 12

AT15 971 U1 2018-10-15 Austrian

Patent Office sen-III phosphate. A 9.9 g / kg snail bait is also known as Ferramol ®. A snail bait with iron ill phosphate is bio-suitable and protects e.g. Earthworms, hedgehogs and bees.

[00126] A snail bait with methiocarb is known, for example, as Mesurol ®.

[00127] According to a further embodiment, the snail bait comprises a sex attractant. The snail bait works better because the snails are attracted more.

[00128] For example, a sex attractant is present in METAREX INOV ®.

According to a further embodiment, the fertilizer has sea lime, in particular coral, algae and / or mussel lime. The chalk, from which the sea lime is obtained, may have arisen from deposits of calcareous algae.

Sea lime is significantly more reactive than, for example, stone or quicklime, which must be ground before application in order to be able to be absorbed by microorganisms at all. As a result, sea lime is more effective even without shredding. Sea lime also improves the absorption of other nutrients. Sea lime is also bio-suitable.

Sea lime is preferably in granular form and can therefore be mixed well with other components of the fertilizer.

The fertilizer may comprise a sea lime fertilizer which has the sea lime. The sea lime fertilizer can consist exclusively of sea lime or comprise further additives, for example elemental sulfur, calcium carbonate and / or magnesium carbonate. For example, the sea lime fertilizer can comprise 82% calcium carbonate (CaCO3), 1.3% magnesium carbonate (MgCO3) and 9% elemental sulfur.

A composition with 92% calcium carbonate and 1.5% magnesium carbonate is also conceivable.

Alternatively, the sea lime fertilizer can have, for example, between 0.1% and 2%, preferably 0.6%, magnesium and between 40% and 60%, preferably 52%, calcium oxide.

The proportion of sea lime in the fertilizer - if present at all - can be between 2% and 12%, in particular between 4% and 8%, preferably 6.4%.

[00136] According to a further embodiment, the fertilizer has crude phosphate. Raw phosphate is bio-suitable. The crude phosphate is particularly soft and can include phosphorus pentoxide (P2O5) soluble in mineral acid.

[00137] The fertilizer can comprise a raw phosphate fertilizer which has the raw phosphate. The raw phosphate fertilizer can consist exclusively of raw phosphate or comprise further additives, for example calcium, in particular CaCO3, magnesium, in particular MgO, aminopurine and / or selenium.

The raw phosphate fertilizer can have, for example, 26% phosphate, 1.2% magnesium, 40% calcium oxide and 0.5% sodium. This is also known on the market as Hyperkorn P26.

A natural phosphate fertilizer with 26% mineral acid-soluble phosphorus pentoxide (P2O5) is also known as natural phosphate P26.

Also known as Litho Physalg ® G18 is a raw phosphate fertilizer with P2O5, CaCO3, MgO and aminopurine.

In addition, a raw phosphate fertilizer with 26% P2O5, 40% CaO and 2% MgO is known as DOLOPHOS ® 26.

DOLOPHOS ® 15 contains, for example, 15% soft earthed raw phosphate (P2O5),

AT15 971 U1 2018-10-15 Austrian

Patent Office% calcium carbonate (CaCO3) and 15% magnesium carbonate (MgCO3).

The proportion of the crude phosphate fertilizer in the fertilizer - if present at all - can be between 4% and 12%, in particular between 5% and 10%, preferably 8%.

All aspects, embodiments and features of the invention described here can be combined with one another, in particular also detached from the specific embodiment in the context of which they are mentioned. In particular, all subjects of the dependent claims can be combined with one another and with each subject of the independent claims.

[00145] The invention is described below by way of example using possible fertilizers.

A first fertilizer, in particular for plants for use in biogas plants, can contain, for example, Alzon® 46, diammonium phosphate with 18% nitrogen and 46% phosphorus, kieserite, Schwedokal® 90 and Excello® 331.

If a GNP fertilizer is used instead of Excello ® 331, the proportion can be chosen accordingly, since the GNP fertilizer has a higher proportion of boron than Excello @ 331.

A third fertilizer, especially for rapeseed, can, for example, Alzon ® 46, diammonium phosphate with 18% nitrogen and 46% phosphorus, a phosphate-potassium fertilizer with 7.5% phosphorus, 40% potassium, 4% sulfate and 10, Contain 8% calcium oxide, kieserite, Schwedokal ® 90 and Excello ® 331. The respective proportions can in principle be chosen arbitrarily. Instead of Excello ® 331, for example, a GNP fertilizer can also be used.

In particular, the fertilizer can e.g. 36.6% Alzon ® 46, 17.65% diammonium phosphate, 25.1% phosphate potash fertilizer, 10% kieserite, 6.7% Schwedokal ® 90 and 4% Excello ® 331. If a GNP fertilizer is used instead of Excello ® 331, the proportion can be chosen accordingly, since the GNP fertilizer has a higher proportion of boron than Excello ® 331.

A fourth fertilizer, especially for soybean, can, for example, diammonium phosphate with 18% nitrogen and 46% phosphorus, a phosphate-potassium fertilizer with 7.5% phosphorus, 40% potassium, 4% sulfate and 10.8% calcium oxide, Kieserit, Schwedokal ® 90, Excello ® 331, sea lime with 0.6% magnesium and 52% calcium oxide, as well as Hyperkorn P26. The respective proportions can in principle be chosen arbitrarily. Instead of Excello ® 331, for example, a GNP fertilizer can also be used.

In particular, the fertilizer can e.g. Contain 17.62% diammonium phosphate, 37.5% phosphate potash fertilizer, 11.3% kieserite, 9.15% Schwedokal ® 90, 10% Excello ® 331, 6.4% sea lime and 8% hyperkorn P26.

In addition to elemental sulfur, the patent office also contains Excello © Weide. In particular, the fertilizer can be designed as NPK fertilizer 7 + 5 + 10 (+ 4MgO + 8S) with 7% Na and 10% to 30%, preferably 15%, sea lime (CaO). The nitrogen can be completely stabilized with 3.5% sulfate and 4.5% elemental sulfur. 0.6 g of selenium, 0.3 g of cobalt, 150 g of zinc and 50 g of copper per 100 kg of fertilizer can be included as micronutrients.

All components of the fertilizer can be present as granules. A wide variety of fertilizers can thus be mixed well to form a new fertilizer.

In order to mix the proportions of the individual fertilizers in the fertilizer as precisely as possible, a metering mixer can be used.

The percentages given relate in each case to% by weight.
