DK 155728BDK 155728B
Den foreliggende opfindelse angår et gødningspræparat, hvori gødningsforbindelsen er et uorganisk gødningsmiddel med et næringsstof, et uorganisk gødningsmiddel med flere næringstoffer, et organisk gødningsmiddel, et organ isk-uorgani sk gød-5 ningsmiddel, et sporstofsgødningsmiddel, et plantebeskyttelsesmiddel eller en kombination deraf, og hvori gødningsforbindelsen er belagt med et vandafvisende og/ eller i vand tungt opløseligt eller i vand kvældende middel, hvorved frigørelse af næringsstofferne begynder på en reguleret måde.The present invention relates to a fertilizer composition wherein the fertilizer compound is an inorganic fertilizer with a nutrient, an inorganic multi-nutrient fertilizer, an organic fertilizer, an organic inorganic fertilizer, a trace fertilizer, a plant protection agent, and a combination protection agent, wherein the fertilizer compound is coated with a water repellent and / or water-soluble or water-swelling agent, thereby releasing the nutrients in a controlled manner.
10 Gødningsmidler er som bekendt stoffer, der er bestemt til tilførsel til nytteplanter med henblik på at fremme disses vækst, forøge deres udbytte eller forbedre deres kvalitet.10 Fertilizers are, as you know, substances intended for application to utility plants in order to promote their growth, increase their yield or improve their quality.
15 Alle kendte faste gødningsmidler stiller i overensstemmelse med deres opløsningshastighed næringsstoffer til rådighed for planterne via jord- eller substratopløsning. Det hører til teknikkens standpunkt at styre opløsningshastigheden således, at næringsstofferne i løbet af et valgbart tidsrum 20 - fra administrationstidspunktet - kan strømme ensartet i overensstemmelse med gødningsmidlets sammensætning.All known solid fertilizers, in accordance with their dissolution rate, provide nutrients to the plants via soil or substrate solution. It is a matter of the prior art to control the rate of dissolution so that during a selectable period of time 20 - from the time of administration - the nutrients can flow uniformly according to the composition of the fertilizer.
Det er imidlertid fælles for alle disse gødningsmidler, at begyndelsen af næringsstofafgiveisen ikke kan styres, hvor-25 ved hurtigt virkende gødningsmidler straks frigør den samlede næringsstofmængde, og langsomt virkende gødning straks frigør delmængder.However, it is common for all of these fertilizers that the onset of nutrient release cannot be controlled, whereby fast-acting fertilizers immediately release the total nutrient load, and slow-acting fertilizers immediately release subsets.
Pra fysiologisk, økologisk og økonomisk synspunkt er det 30 enten ønskeligt eller nødvendigt at forøge udnytteligheden af gødningsmidler og dermed deres effektivitet, så at man ved en enkelt høj samlet forbrugsmængde og dermed det mindst mulige administrationsopbud undgår eller i det mindste kraftigt formindsker fytotoksicitet samt miljøbelast-ning som følge af udvaskningstab.From a physiological, ecological and economical point of view, it is either desirable or necessary to increase the utilization of fertilizers and thus their efficiency, so as to avoid or at least sharply reduce phytotoxicity and environmental impact by a single high total consumption and thus the lowest possible administrative supply. due to leaching losses.
Den foreliggende opfindelse tager derfor sigte på at angive et gødningsmiddel, der først på et ønsket tidspunkt stiller næringsstofferne til rådighed i den ønskede mængde.The present invention therefore aims to provide a fertilizer which only at a desired time provides the nutrients in the desired amount.
DK 155728 BDK 155728 B
22
Dette opnås ved hjælp af gødningspræparatet ifølge opfindelsen, der er ejendommeligt ved, at gødningsforbindelsen til regulering af frigørelse af næringsstofferne er belagt med en oliemodificeret alkydharpiks og jernpalmitat eller med en al-S kydharpiksopløsning og polyvinylalkoholopløsning eller med en alkydharpiksopløsning og polyvinylalkoholopløsning samt en tværbunden methylsiloxanhærdningsmiddelblanding, hvorhos belægningslaget har en tykkelse på 10~8-10“2m.This is achieved by the fertilizer composition according to the invention, characterized in that the fertilizer compound for regulating the release of the nutrients is coated with an oil-modified alkyd resin and iron palmitate or with an al-S hydrocarbon resin solution and polyvinyl alcohol resin solution or with an alkyd resin alcohol solution and with an alkyd resin solution. wherein the coating layer has a thickness of 10 ~ 8-10 "2m.
10 I en hensigtsmæssig udførelsesform for gødningspræparatet ifølge opfindelsen foreligger dettte som gødningspulver, krystallinsk gødning, granuleret gødning, belagt gødningsgranulat, gødningsstave eller indkapslet gødningsopløsning eller -suspension.In a convenient embodiment of the fertilizer composition according to the invention, these are available as fertilizer powder, crystalline fertilizer, granular fertilizer, coated fertilizer granules, fertilizer rods or encapsulated fertilizer solution or suspension.

Opfindelsen angår endvidere en fremgangsmåde til fremstilling af det omhandlede gødningspræparat.The invention further relates to a process for the preparation of the present fertilizer composition.
25 Fremgangsmåden ifølge opfindelsen er ejendommeligt ved, at gødningsforbindelsen indføres i en anordning, som er hensigtsmæssig for den pågældende behandling, til hvilken anordning et belægningsmiddel sættes, så at gødningen bliver fuldstændigt og tilstrækkelig ensartet belagt med en belægning med ønsket 30 lagtykkelse, eller at belægningsmidlet indføres i en passende anordning, og gødningsforbindelsen tilsættes, så at gødningen bliver fyldstændigt og tilstrækkelig ensartet belagt med en belægning med ønsket tykkelse.The method according to the invention is characterized in that the fertilizer compound is introduced into a device suitable for the particular treatment to which device a coating agent is applied so that the fertilizer is completely and sufficiently uniformly coated with a coating of the desired layer thickness or that the coating agent is applied. is introduced into a suitable device and the fertilizer compound is added so that the fertilizer is fully and sufficiently uniformly coated with a coating of the desired thickness.
35 Næringstofferne kan være omsluttet af vandafvisende midler valgt blandt paraffiner, voksarter, metalsæber, kvartære ammoniumforbindelser, urinstofderivater, fedtsyremodificerede harpikser, siliconer og/eller perf 1uorerede organiske forbindelser .The nutrients may be surrounded by water repellents selected from paraffins, waxes, metal soaps, quaternary ammonium compounds, urea derivatives, fatty acid modified resins, silicones and / or perfluorinated organic compounds.
DK 155728 BDK 155728 B
3 Næringstofferne kan også være omsluttet af i vand tungt opløselige eller i vand kvældbare midler valgt blandt polymere med vandbefugtende grupper, hvor der med vandbefugtende grupper er tale om hydroxyl-, carboxyl-, alkylester-, cyan-, chlor eller 5 fluorgrupper.The nutrients may also be surrounded by water-soluble or water-swellable agents selected from polymers with water-wetting groups, with water-wetting groups being hydroxyl, carboxyl, alkyl ester, cyano, chloro or fluorine groups.
De i vand tungt opløselige eller i vand kvældbare midler kan være polyvinylalkoholer, fortrinsvis med et restacetyl indhold på 10%.The water-soluble or water-swellable agents may be polyvinyl alcohols, preferably with a residual acetyl content of 10%.
10 Næringsstofferne kan også være omsluttet af i vand tungt opløselige midler valgt blandt uorganiske forbindelser, hvor der med de i vand tungt opløselige midler er tale om jernphosphat eller calciumphosphat.The nutrients may also be surrounded by water-soluble agents selected from inorganic compounds, the water-soluble agents being iron phosphate or calcium phosphate.
1515
Endvidere kan næringsstofferne være omsluttet af i vand tungt opløselige eller i vand kvældbare midler valgt blandt polymere med vandbefugtende grupper eller valgt blandt uorganiske forbindelser samt omsluttet af vandafvisende midler valgt blandt 20 paraffiner, voksarter, metalsæber, kvartære ammoniumforbindel-ser, urinstofderivater, fedtsyremodificerede harpikser, s i 1 i -coner og/eller perf 1uorerede organiske forbindelser.Furthermore, the nutrients may be enclosed in water-soluble or water-swellable agents selected from polymers with water-wetting groups or selected from inorganic compounds and enclosed by water-repellent agents selected from 20 paraffins, waxes, metal soaps, quaternary ammonium compounds, urea derivatives, fatty acid modified resins, si 1 in -cones and / or perfluorinated organic compounds.
Det vandafvisende middel omslutter næringsstoffet med en lag-25 tykkelse fra 10-8 m til 10-2 m, fortrinsvis fra 1 x 10~8 m til lx 10-3 m.The water repellent encloses the nutrient with a layer thickness of 10-8 m to 10-2 m, preferably from 1 x 10 ~ 8 m to 1 x 10-3 m.
Det i vand tungt opløselige eller i vand kvældbare middel omslutter næringsstofferne med en lagtykkelse fra 10“6 m til 3Q 10“2 m, fortrinsvis fra 5 x 10~5 til 2 x 10"3 m.The water-soluble or water-swellable agent encloses the nutrients with a layer thickness of 10 "6 m to 3Q 10" 2 m, preferably from 5 x 10 ~ 5 to 2 x 10 "3 m.
Gødningsmidlet ifølge opfindelsen har overraskende en tidsmæssigt forsinket indtrædende næringsstofafgivelse, hvis begyndelse - alt efter det ønskede formål - kan styres 35 således, at næringsstofstrømningen først begynder efter forløbet af en forsinkelsestid fra 1 dag til 2 år, fortrinsvis fra 30 til 180 dage.Surprisingly, the fertilizer according to the invention has a delayed onset of nutrient release, the beginning of which - depending on the desired purpose - can be controlled such that the nutrient flow begins only after the elapsed time from 1 day to 2 years, preferably from 30 to 180 days.
DK 155728BDK 155728B
44
Med denne styrede næringsstofafgivelse er forbundet mange fordele, der ikke kan opnås ved anvendelse al de kendte gødningsmidler.Associated with this controlled release of nutrients are many benefits that cannot be achieved by using all the known fertilizers.
5 Gødningen kan således eksempelvis gennemføres i henhold til behovet, idet næringsstofafgivelsen indstilles efter planternes maksimumbehov og minimumbehov, hvilket ikke er muligt med nogen af de kendte gødningsmidler.Thus, for example, the fertilizer can be carried out according to the need, the nutrient delivery being adjusted to the maximum and minimum requirements of the plants, which is not possible with any of the known fertilizers.
10 Herved kan planternes forskellige næringsstofbehov i løbet af en dyrkningsperiode opfyldes optimalt, hvorved beskadigelser af planterne som følge af overgødning på tidspunkter med stor plantefølsomhed eller utilstrækkelig vækst som følge af tilførsel af utilstrækkelige næringsstofmængder på 15 tidspunkter med det største behov fordelagtigt undgås.Hereby the various nutrient needs of the plants during a growing period can be optimally met, thereby advantageously avoiding damage to the plants due to fertilization at times of high plant sensitivity or insufficient growth as a result of supply of insufficient nutrient quantities at 15 times of greatest need.
Den ved hjælp af gødningsmidlet ifølge opfindelsen regulerbare frigørelse af næringsstofleverancen har yderligere den fordel, at planternes udbyttepotential også udtømmes fuldt 20 ud under klimatisk ugunstige betingelser eller på jord med ringe frugtbarhed, hvorved hidtil lukkede veje åbnes til gødning med høj ydelse.The fertilizer delivery adjustable by the fertilizer according to the invention further has the advantage that the yield potential of the plants is also fully depleted under climatic adverse conditions or on soil with poor fertility, thus opening closed roads to high yield fertilizers.
Endvidere åbner den ved hjælp af gødningsmidlet ifølge 25 opfindelsen regulerbar frigørelse af næringsstofstrømmen mulighed for optimalt at opfylde de vekslende krav i henseende til næringsstofformer og deres koncentrationer i en speciel kultur ved hjælp af en ved udsåningen eller udpot-ningen én gang tilført samlet gødningsmængde, hvorved den 30 risikofyldte og i tilfælde af forkert tidsfastsættelse ineffektive eftergødning bortfalder.Furthermore, it allows for adjustable release of the nutrient stream by means of the fertilizer according to the invention, to optimally fulfill the varying requirements with regard to nutrient forms and their concentrations in a particular culture by means of a total amount of fertilizer once applied at sowing or potting. the 30 risky and in case of incorrect timing ineffective post fertilizer lapses.
Den ved hjælp af gødningsmidlet ifølge opfindelsen regulerbare frigørelse af næringsstofferne åbner endvidere mulig-35 hed for at sætte gødningsmidler til substrater længere før deres udnyttelse, uden at der ved begyndende udnyttelse må regnes med høje, allerede aktive saltindhold, da disse 5Furthermore, the release of the nutrients regulatable by the fertilizer according to the invention opens the possibility of adding fertilizers to substrates longer before their use, without having to expect high, already active salt content at initial use, as these
