Abstract
Plant-promoting preparations with controlled-start plant-promoting agent release, especially fertiliser preparations with controlled-start nutrient release, characterised in that the preparations containing the plant-promoting agent enveloped in an enveloping agent selected from water-repellent substances, substances that are sparingly soluble in water and substances capable of swelling in water. The preparations have a delayed-start promoting agent release the time of which can be controlled according to the desired purpose for which they are used.
Description
The present invention in concerned with plantprorating preparation· vith controlled-atart plant5 prorating agent release, especially fertiliser preparations vith eontrollsd-start nutrient release, and vith their use. ka is known, fertilisers are auhatanees intended to be fed to cultivated plants in order to prorata their growth, increase their yield, or improve their quality. All knovn solid fertiliser preparations sake nutrients available to tha plants by way of the aoll and/or substrata solution according to the speed with which, they dissolve. The state of the art is to con15 trol the speed at which they dissolve in such a way that the nutrients can flov uniformly according to the composition of the fertiliser preparation during a selected period of tiae, from the tiae of application onwards. .
A common factor with all these fertilisers, however, is that the start of the nutrient release '««n?* be controlled, so that fast-acting fertilisers release the vhole of the amount of the nutrients immediately and the alow-acting fertilisers liberate a part of the amount of the nutrients immediately. f r» Γ» Ο Ο «J ο CJ • 2 * For physiological, ecological and economic reasons it ia desirable and/or necessary to increase tbs utilisation of fertiliser preparations, and thus their effectiveness, in such a way that with a single high total outlay and thus with the lowest possible application cost both phytotoxicity and pollution due to leachlng-out losses are avoided or at least reduced to a great extent.
The problem upon which the present Invention is based has therefore been to provide a fertiliser preparation which makes the nutrients available only at a desired time and in the required amounts, This problem is now solved according to the present Invention by the preparations, ae defined below.
The present invention provides a plant-promoting preparation which comprises a plant-promoting agent, as hereinafter defined, enveloped in an enveloping agent, the composition of the enveloping agent comprising a substance selected from 1) a water-repellent metal salt of lauric acid, yristic acid, palmitic acid or oleic acid, ii) a water repellent magnesium, calcium, copper, sine, manganese, zirconium or aluminium salt of stearic acid, 54+) a water-repellent fatty acid-modified reein, iv) a water-repellent silicone, - 3 ▼) a polyvinyl polymer containing free hydroxyl groups and acetyloxy groups, the polymer being sparingly soluble in water, vi) an iron oxide hydrate or a calcium phosphate 5 that ie sparingly soluble In water, vii) a polyvinyl polymer containing free hydroxyl groups and acetyloxy groups, the polymer being capable of swelling in water and viii) a gelatin capable of availing in water.
The new preparations have a delayed-start plantpromoting agent release the time of which can be controlled according to the desired purpose for which they are used by choosing for the composition of the enveloping agent one or mors of the water-repellent substances, substances that are sparingly soluble in water and substances capable of swelling in water defined in the aforesaid groups i) to viii).
By the term a plant-promoting agent there is to be understood herein any agent capable of promoting the growth of a plant in a desired manner. The plantpromoting agent is preferably, however, a fertiliser.
Particular embodiments of the plant-promoting preparations of the present invention are that: the plant-promoting agent is an inorganic single nutrient fertiliser, aa inorganic fertiliser contnAnieg two or or* nutrients, an organ©-Inorganic fertiliser, an organic fartlliaar or a trace nutrient or a combination of two or aore auoh eubetanoes, the plant-promoting agent la a fertiliser in the fora of a powder, a crystalline fertiliser, a granular fertiliser, a fertiliser in the fora of coated granules, a fertiliser in the fora of rod-shaped pellets, an encapsulated fertiliser solution or an encapsulated fertiliser suspension, the plant-proaoting agent is a fertiliser containing at least one nutrient selected froa the eleaente carbon, oxygen, nitrogen, phosphorus, potasBiua, magnesium, calcium, sulphur, iron, manganese, copper, sine, chlorine, boron, molybdenum, sodium, silicon, cobalt and aluminium, the or each element being present in the form of a compound, the water-repellent metal salt of palmitic acid is iron palmitate, the polyvinyl polymers defined in the aforesaid groups v) and vii) are polyvinyl alcohole containing a residual acetyl content of 10%, the composition of the enveloping agent comprises (a) a substance selected from tbe aforesaid groups v), vi) and vii) and (h) a eubstance selected froa the aforesaid groups i), il), iii) and iv), 52G38 tbe composition of th· enveloping agent comprises a eubetance «sleeted froa th· aforesaid group· i), ii), iii) and ir) and th· thickness of th· enveloping agent surrounding th· plaat-proaoting agent 1· within the O range of froa 10 a to 10 a, preferably froa 1 . lO^a to 2 . 10“3a, the coapooition of the enveloping agent comprises a substance selected froa the aforesaid groups r), ri), Til) and riii) and the thickness of the enveloping agent surrounding the plant-promoting agent is within the rang· of froa 10 a to 10 a, preferably froa 5 . 105a to 2 . 10“3a.
The fertiliser preparations according to .the present invention have, surprisingly, a nutrient release which starts after a time lag and the start of which can he controlled according to the desired purpose hy the choice of an appropriate enveloping agent composition, so that the flow of nutrients doss not begin under average natural conditions until a delay tine of, for example, froa 1 day to 2 years, preferably froa 30 to 180 days, has elapsed.
The coaposition of the enveloping agent aay thus be such that it is capable of releasing the plantpromoting agent, for example a fertiliser, under average natural conditions within a period of froa 1 day to 2 years. preferably from 30 to 180 day·» After the preparation of the present Invention has been Introduced Into soil, having regard of course to the local climate of the area for which eueh a particular preparation ie intended and the desired tine at which the plant-promoting agent should be released. Many advantages which cannot be obtained by the use of the hitherto known fertiliser preparations result froa this controlled nutrient release.
Thus, for example, fertilising can he carried out according to actual requirements, with the nutrient release being adjusted to aeet the peak requirement and the sero requirement of the plants, and this is not possible with any of the previously known fertilisers.
By this mesne the varying nutrient requirements of plants during a cultivation period can be met to the optimum, this of course being an advantage; thus damage to the plante due to over-fertilising during periode of high plant sensitivity, or insufficient growth due to an inadequate supply of nutrients when requirements are at a maximum can be avoided.
The composition of the enveloping agent may thus be eueh that it is capable of controlling the release of the plantpromoting agent, for example a fertiliser, in a way suited to the nutrient requirements of the plant to he treated with the preparations of the present invention, so that over-fertill25 sins and/or unacceptable leaching-out loesee are avoided.
Tne liberation of the nutrient supply which can be controlled by means of the fertiliser preparations -Ί according to tb· present invention also offers the advantage of fully realising tbs yield potential of plants even under unfavourable climatic conditions or on soils with poor fertility, thus opening up avenues for high performance fertilising which vers previously not possible.
Furthermore, the liberation of tbs nutrient flow which can he controlled by means of the fertiliser preparations according to the present invention offers the possibility of satisfying to an optimum degree the changing demands with regard to nutrient forma and their concentration for a special cultivation by means of a single total quantity of fertiliser applied at sowing time or whan potting, so that risky follow-up fertili15 sing, which is Ineffective when carried out at the wrong time, can be omitted* The liberation of the nutrient supply which, can be controlled by means of the fertiliser preparations «apn-rding to the present invention also offers the possibility of adding fertilisers to substrates long before the latter are used, without having to take into account high salt contents that ars already active when use is commenced, since they are first activated by watering of the substrates when their use commences, so that salt shock and/or salt damage can be avoided. Thus, - θ depending on the natural conditions, an artificial watering of substrates previously treated vith the novel preparations may be carried out in order to liberate the nutrient supply.
The following fertilisers may be used as the plantpromoting agent in accordance vith the present invention: - fertiliser powders - crystalline fertilisers - granular fertilisers - granular coated fertilisers - fertilisers in the form of rod-shaped pellets - encapsulated fertiliser solutions or suspensions.
The above-mentioned fertilisers may be: - inorganic single nutrient fertilisers - inorganic multi-nutrient fertilisers - organo-inorganic fertilisers - organic fertilisers - trace nutrients - combinations of the above-mentioned components.
As the plant-promoting agent there may also be used fertilisers that have been subjected to any pre-treatment, for example fertilisers vith a retarded release of the plant nutrientB, among which sparingly soluble salts, polymeric nutrient compounds and nutrients chemically or physically bound to natural and synthetic 53338 - 9 carriers may be mentioned by way of example.
The present invention also provides * method of promoting the development of a living plant, wherein the area in the vicinity of the living plant ie treated with a preparation of the present invention.
The present invention further provides a method of promoting the development of crop plants in a crop area, wherein the crop area ie treated with a preparation of the present invention, is indicated ahove, a ingle treatment of the crop area may he carried, out at the start of the crop plants' growth with an amount of the preparation that is sufficient for the crop plants until they are fully developed; another possibility is for the treatment to be carried out before the crop plants are sown in the crop area.
