Description

Preparations providing a nutrient source for plants and a process for making such preparations

TECHNICAL FIELD

The invention relates to preparations serving as a nutrient source of plants and for reducing heavy metal and isotope absorption and tolerating injuries brought about by them as well as for reducing the pesticide requirement and a process for the preparation thereof.

BACKGROUND ART

It is well known that in agriculture some preparations containing nutrients to improve the yield are used, such as organic manure, fertilizers, foliar fertilizers as well as large quantities of pesticides which are applied to the plants or their environment, in order to eradicate pests and parasites. Of these preparations, those containing synthetic active ingredients have numerous side-effects in addition to the desired impact. For example the application of large quantities of fertilizers containing nitrogen, phosphorus and potassium may lead to deficiency symptoms reflecting the lack of micro-elements in plants (S. Kiss: Magnesium fertilizers, magnesium in biology. Agricultural Publishing House, Budapest 1983. W. Bergmann: Occurrence and recognizing of nutrition disturbances in cultivated plants, Agricultural Publishing House, Budapest 1979) . This - in addition to retarding the development and growth of plants - also results in the plant generating less growth and development factors (amino-acid, vitamins and enzimes) so important for the human and animal body. Besides, residuals of pesticides may cause different grades and manifestations of poisoning in humans and animals, and they are also the cause of polluting the soil and natural waters.

One of the detrimental side-effects of industrial production is that various pollutants such as heavy metals and acid rain generating gases are introduced into the environment, polluting the lithosphere, the hydrosphere and the atmosphere. The pollutants are introduced through the feeding chain into the human and animal bodies, possibly leading to poisoning and related diseases.

In the operational breakdowns of nuclear power stations or upon experimental nuclear explosions, radio nuclides are introduced into the biosphere. Of these, the ones with a long half-period, such as Sr-90 and Cs-137 could cause radiation diseases for many thousands of years.

Consequently, approaches and preparations are required by which the nutrient demand of plants, animals and people can be met without detrimental side-effects, while reducing the quantity of pesticides applied, along with the heavy metal and isotope absorption of plants, and facilitating repairing and recovery possesses.

The basis for the invention is the recognition that if the soluble salts and/or complexes of macro and/or micro elements important from a physiologic aspect are applied to the plants or their environment together with the extract of plants containing biocide and/or repellent ingredient, the disadvantages mentioned above can be avoided or mitigated.

Macro-elements important for physiological processes are the chemical elements such as C, 0, N, H, P, K, Ca, Mg, S, Si, Na, Cl, Fe and Al occurring in a relatively large quantity in the organic structures of all living creatures.

Physiologically important micro-elements are the chemical elements existing in a very low quantity in the organizations of living creatures, the lack of which, however, causes functional troubles, or toxicity if they are present in a volume higher than required, such as B, Zn, Cu, Mn, Ti, Li, F, Br, Ni, Rb, Sn, Sr, Ba.

Macro and micro elements may also be applied partly or fully in the form of rocks containing such elements.

DISCLOSURE OF THE INVENTION

The subject of the invention covers the preparations serving as a nutrient source for plants, in addition to reducing and helping to tolerate the heavy metal and isotope absorption while decreasing the pesticide volume needed. The active ingredients of these preparations are the soluble salts and/or complexes of physiologically important macro and/or micro elements and/or the rocks containing such materials and the extract of plants containing biocide and/or repellent active ingredient. We have also found that the impact of preparations can be improved in a target-oriented way, by adding inorganic or organic acids, phytohormons and/or vitamins.

The macro and micro elements of the preparation embodied by the invention are selected according to the requirements of the plants to be treated, as well as taking into consideration the demand of animals and human beings.

The various elements can be applied in the form of their soluble salts and/or complexes. As a complex, especially favourable use can be made of chelates.

As the source of macro and micro elements, the following compounds are listed as examples.

As a nitrogen source, ammonium nitrate or ammonium sulphate can be used. In relation to elementary nitrogen, a percentage by weight of 0.01 to 40 is adjusted.

Plants containing biocide and/or repellent active ingredient are plants which contain pesticide, such as bactericide, viricide, insecticide, fungicide, miticide or vermicide or repellent materials.

As examples for such plants, the following are mentioned: mustard (Brassica juncea Czern.) absinth (Artemisia absinthium L.) , chamomile (Matricaria chamomilla L.) , calendula (Calendula officinalis L.), thyme (Thy us vulgaris L.), horsetail (Ephedra equisetine Bge.), borago (Borago officinalis L.), caraway (Caru carvi L.), black radish (Raphanus sativum) , quince (Cydonia oblonga Mill.), rose (Rosa L.), sage (Lepidium sativum L.), walnut (Juglans regia L.), ricinus (Ricinus communis L.) paprika (Capsicum annua L.), mallow (Althaea officinalis L.) , hyppophae (Hyppophae rhamnoides L.), celery (Apium gravedens L.), normal sage (Salvia officinalis L.), bidens (Bidens tripartitus L.), abutilon (Abutilon Adans) , chrysanthenum (Chrysenthenum vulgare L. , Phyrethrum Bois. ) , lavender (Lavendula officinalis L.), buckwheat (Fagopyrum Geartu.), St.John's wort (Hypericum perforatum) , horse radish (Verbascum thapsiforme) , plantain (Plantago major L.) , anise (Pimpinella anisum L.), aloe (Aloe arborescens Mill.), rhubarb (Rhenum officinale) , garlic (Alliu sativum L.), nettle (Urtica dioica L.).

Plant extracts applicable as components of the preparations embodied by the invention are available from trade or they can be produced by extraction, vapour distillation and/or pressing of the plant organs containing the active ingredient, for example the flower, leaves, root, berries or seed.

The plant extracts available from trade include the active ingredients of one or more plants. Such abstracts are for example the products marketed under the names Aromex and Fresta.

Extraction may be carried out by an organic extracting agent, for example by alcohol, some kind of an oil or acid or by the mixtures of these. As mentioned above, the effect of the preparations embodied by the invention may be enhanced by adding inorganic or organic acids, phytohormons and/or vitamins.

Such inorganic or organic acids can be used which do not harm the plants in the concentration applied.

A further advantage of using inorganic or organic acids is that they shift the pH rate of the preparation to the acid range, and as a result the nutrient absorption of plants to be treated is enhanced.

An inorganic acid that can be applied beneficially is phosphoric acid, while as an organic acid, lactic acid, citric acid, malic acid, butanedioic acid, acetic acid etc. can be applied.

Phytohormons and vitamins are also boosting agents. As phytohormons, it is advantageous to use auxins, gibberellines, cytokinins, abscisic acid and ethylene. As vitamins, advantageous use can be made of thiamine- hydrochloride, aneurin, pyridoxine and nicotine acid. The quantity of these materials amounts to between 1 μg and 50 g per one litre of the preparation.

For the preparations embodied by the invention, if necessary suspending agent such as bentonite, alginite or vinace is added. The latter materials partly improve the viscosity of the preparation and partly increase the active colloide surface of the preparation. The retarded effect of the preparation is ensured by the absorbed cations on the surface of the colloides.

The accurate composition of the preparation embodied by the invention is selected according to the objective to be accomplished. If the preparation is used as a plant nutrient, through their application the mineral content of plants can be increased in a target-oriented way, meaning the iron, calcium, magnesium, copper, selenium or zinc content. In this way, in addition to increasing the plant yield, it better corresponds to the mineral requirement of the person or the animal species to be fed.

To supply pregnant women and small children, for example, vegetables and fruit with a high iron content can be produced. This can be achieved by spraying the vegetables and fruit with a high iron content preparation.

Lucern intended to feed high milking capacity cattle for example is sprayed with a high calcium and magnesium preparation and so the fodder will also have a higher calcium and magnesium content.

If the preparation embodied by the invention is intended for reducing and tolerating the heavy metal absorption of plants, first soil and plant analysis is carried out, i.e. it is determined what heavy metals are present, and in which concentration and form. In the knowledge of these factors is the composition selected and such a preparation is produced which has a high calcium and magnesium content and a significant micro-element content. When plants are sprayed with such a preparation, the plant organs above the soil are saturated with calcium, magnesium and micro elements, thereby antagonizing (reducing) the absorption of heavy metals and facilitating the toleration of the plant. The micro elements phytohormons and/or vitamins in the preparation boost the enzyme activities of the plants, thereby contributing to tolerating heavy metal pollution.

If the preparation embodied by the invention is designed to reduce and tolerate isotope absorption by the plants, again soil and plant analysis precedes the selection of composition. Once this information is gathered, we can increase in the preparation the concentration of the stable forms of polluting isotope(s) or that of the antagonist isotopes. Thus, for example in the case of Sr-90, we increase the concentration of calcium and magnesium and also that of stable stroncium, in the case of Cs-137 the concentration of potassium, calcium and magnesium and in the case of J-131 that of stable iodine is increased. At the same time, we also enhance the concentration of elements able to change their valence (e.g. copper, manganese, iron) and B-vitamins and phytohormons to encourage the processes of rerairing and recovering the damage caused by radiation.

The plant extracts applied in the preparations embodied by the invention - in addition to exerting a biocide effect themselves, thus reducing the necessary quantity of other pesticides, also assist the nutrient uptake of plants.

The preparations embodied by the invention are produced in the following way.

To the biocide effect plant extract or to the mixture of multi biocide effect plant extracts, the salts and/or complexes of macro and micro elements selected according to the purpose to be achieved are added, and then the mixture is supplemented as required by one or more phytohormon and/or vitamin and/or inorganic or organic acid and if necessary also by a suspending agent.

If the macro and micro elements are used in the form of rocks, one or more rocks selected on the basis of its nutrient content are crushed to 1 nm - 10 mm size, and this is added to the plant extract(s) of biocide effect. If only a part of the macro and micro elements is applied in the form of rocks, the lacking nutrients are supplied by their salts or complexes.
