Abstract
Description
Foreliggende oppfinnelse gjelder et middel for hemming av nitrifikasjonen av ammoniumnitrogen, spesielt i mineralske og organiske gjødningsmidler i jord. The present invention relates to an agent for inhibiting the nitrification of ammonium nitrogen, especially in mineral and organic fertilizers in soil.
Det er kjent at ammoniumnitrogen i jord relativt raskt omdannes til nitratnitrogen ved hjelp av bakterier. Denne nitri-fikasjonsprosess påvirkes av temperatur, jordfuktighet, pH-verdi såvel som biologisk aktivitet i jorden. It is known that ammonium nitrogen in soil is relatively quickly converted into nitrate nitrogen with the help of bacteria. This nitrification process is affected by temperature, soil moisture, pH value as well as biological activity in the soil.
Da nitratnitrogenet i motsetning til ammoniumnitroge-net ikke fastholdes til jorddeler, kan det lett utvaskes ved nedbør, fremfor alt på lett, gjennomtrengelig jord. På denne måte går nitrogenet tapt som viktig næringsstoff for plantene. Utover dette kan også en nitratanrikninq i grunn- henholdsvis drikkevannet tilkomme, noe som eventuelt kan føre til sunnhets problemer. As the nitrate nitrogen, in contrast to the ammonium nitrogen, is not fixed to soil particles, it can easily be washed out by rainfall, above all on light, permeable soil. In this way, the nitrogen is lost as an important nutrient for the plants. In addition to this, a nitrate enrichment in the groundwater or drinking water can also occur, which can possibly lead to health problems.
Ved siden av utvaskningstapene opptrer også betydelige, gassformige nitrogentap ved denitrifikasjon av nitratnitrogenet. Alongside the leaching losses, significant gaseous nitrogen losses also occur during denitrification of the nitrate nitrogen.
Ved tilsetning av nitrifikasjonshemmende midler kan disse nitrogentapene minskes og utnyttelsen av nitrogenholdige gjødningsmidler forbedres avgjørende. By adding nitrification-inhibiting agents, these nitrogen losses can be reduced and the utilization of nitrogen-containing fertilizers improved decisively.
Det er således for dette formål utviklet en rekke nitrifikasjonshemmende midler, eksempelvis på basis av pyridin-, anilin-, klor- eller svovelderivater. A number of nitrification-inhibiting agents have thus been developed for this purpose, for example based on pyridine, aniline, chlorine or sulfur derivatives.
Disse forbindelser oppviser imidlertid forskjellige ulemper i praksis, som for eksempel høy flyktighet, hvilket gjør det nødvendig med en for stor tilsetning til jorden. Dessuten er disse forbindelser som regel toksiske og/eller etterlater toksiske rester i jorden. Fra et økologisk siktemål er derfor bare slike, kjente nitrifikasjonshemmende substanser å anbefale for den praktiske anvendelse, som hverken er toksiske eller medfører restproblemer. Til disse hører fremfor alt nitrogenholdige forbindelser, som for eksempel dicyandiamid, guanylthiourea eller ammoniumthiosulfat, som nedbygges full-stendig i jorden til nitrogen som står til disposisjon for plantene. ulemper ved disse forbindelser, eksempelvis sammen-lignet med pyridinderivater, er den mindre virksomhet hhv. virkningsvarighet. De må derfor anvendes i større mengder, hvorved det ikke bare oppstår finansielle, men også en rekke anvendelsestekniske problemer. However, these compounds show various disadvantages in practice, such as high volatility, which makes it necessary to add too much to the soil. Moreover, these compounds are usually toxic and/or leave toxic residues in the soil. From an ecological point of view, only such known nitrification-inhibiting substances can be recommended for practical use, which are neither toxic nor cause residual problems. Above all, these include nitrogen-containing compounds, such as dicyandiamide, guanylthiourea or ammonium thiosulphate, which are completely broken down in the soil into nitrogen that is available to the plants. disadvantages of these compounds, for example compared to pyridine derivatives, is the smaller activity or duration of effect. They must therefore be used in larger quantities, whereby not only financial problems arise, but also a number of application technical problems.
Foreliggende oppfinnelse hadde derfor som oppgave å utvikle et nitrifikasjonshemmende middel, som ikke oppviser de nevnte ulemper ifølge teknikkens stand, men har en utmerket virksomhet og gode anvendelsesmuligheter og som ikke medfører toksikologiske eller restproblemer. The present invention therefore had the task of developing a nitrification-inhibiting agent, which does not exhibit the aforementioned disadvantages according to the state of the art, but has excellent activity and good application possibilities and which does not entail toxicological or residual problems.
Denne oppgave løses ifølge oppfinnelsen ved hjelp av et nitrifikasjonshemmende middel, som består av According to the invention, this task is solved by means of a nitrification-inhibiting agent, which consists of
a) dicyandiamid oga) dicyandiamide and
b) guanylthiourea og/eller ammoniumthiosulfat og/eller ammoniumfosfat. b) guanylthiourea and/or ammonium thiosulphate and/or ammonium phosphate.
Det har nemlig overraskende vist seg at midlet ifølge oppfinnelsen bevirker en vesentlig mer intensiv og mere lang-varig hemming av nitrifikasjonen enn den som en addisjon av hemmevirkningene av enkeltbestanddelene a) og b) gir. It has surprisingly been shown that the agent according to the invention causes a significantly more intensive and longer-lasting inhibition of nitrification than that which an addition of the inhibitory effects of the individual components a) and b) gives.
Denne synergistiske effekt, som også er sterkt utpreget ved kombinasjonen av flere enkeltbestanddeler, var på ingen måte å forutse. This synergistic effect, which is also strongly pronounced in the combination of several individual components, was in no way predictable.
Det nitrifikasjonshemmende middel ifølge.den foreliggende oppfinnelse består av bestanddelene a), nemlig dicyandiamid, og minst én ytterligere bestanddel b), valgt fra gruppen guanylthiourea, ammoniumthiosulfat og ammoniumfosfat, slik at det består av to til fire enkeltbestanddeler. The nitrification inhibitor according to the present invention consists of components a), namely dicyandiamide, and at least one further component b), selected from the group of guanylthiourea, ammonium thiosulphate and ammonium phosphate, so that it consists of two to four individual components.
Forholdet mellom enkeltbestanddelene kan varieres innen vide grenser, hvorved den synergistiske effekt naturligvis er mer eller mindre skarpt utpreget. The ratio between the individual components can be varied within wide limits, whereby the synergistic effect is naturally more or less sharply pronounced.
Av tokomponentsystemene foretrekkes blandinger bestående av 20 til 80 vekt% dicyandiamid såvel som 20 til 80 vekt% guanylthiourea. Of the two-component systems, mixtures consisting of 20 to 80% by weight of dicyandiamide as well as 20 to 80% by weight of guanylthiourea are preferred.
Som trekomponentsystemer har blandinger som består av 20 til 70 vekt% dicyandiamid As three-component systems, mixtures consisting of 20 to 70% by weight of dicyandiamide
20 til 70 vekt% ammoniumthiosulfat20 to 70% by weight ammonium thiosulfate
10 til 60 vekt% ammoniumfosfat10 to 60% by weight ammonium phosphate
vist seg særlig gunstige.proved particularly favorable.
Endelig kan midlet ifølge oppfinnelsen anvendes som firekomponentsystemer, hvorved dette fortrinnsvis består av 20 til 60 vekt% dicyandiamind Finally, the agent according to the invention can be used as four-component systems, whereby this preferably consists of 20 to 60% by weight dicyandiamine
20 til 60 vekt% guanylthiourea20 to 60% by weight guanylthiourea
10 til 50 vekt% ammoniumthiosulfat10 to 50% by weight ammonium thiosulfate
10 til 50 vekt% ammoniumfosfat.10 to 50% by weight of ammonium phosphate.
Som ammoniumfosfat innenfor rammen av foreliggende oppfinnelse skal det forståes ammoniumholdige fosfatforbindelser, spesielt ammoniumdihydrogenfosfat, diammoniumhydrogenfosfat såvel som ammoniumpolyfosfat. Ammonium phosphate within the scope of the present invention is to be understood as ammonium-containing phosphate compounds, in particular ammonium dihydrogen phosphate, diammonium hydrogen phosphate as well as ammonium polyphosphate.
Det nitrifikasjonshemmende middel ifølge oppfinnelsen kan anvendes såvel alene som også i kombinasjon med nitrogenholdige gjødningsmidler. The nitrification-inhibiting agent according to the invention can be used both alone and in combination with nitrogen-containing fertilisers.
Dersom det anvendes uten gjødningsmidler, anbefalesIf it is used without fertilisers, it is recommended
en anvendelsesmengde fra 0,1 til 300 kg/ha, fortrinnsvis 1 til 60 kg/ha, hvorved utbringelsen enten kan foregå før, samtidig med eller etter gjødslingen. an application rate of from 0.1 to 300 kg/ha, preferably 1 to 60 kg/ha, whereby the application can either take place before, at the same time as or after fertilisation.
Dersom midlet ifølge oppfinnelsen derimot anvendes i kombinasjon med det nitrogenholdige gjødningsmiddel, hvis nitrifikasjon det skal hemme, anvendes det hensiktsmessig i en mengde på 0,1 til 30 vekt%, fortrinnsvis 1 til 15 vekt% beregnet på gjødningsmidlet. If, on the other hand, the agent according to the invention is used in combination with the nitrogen-containing fertiliser, the nitrification of which it is to inhibit, it is suitably used in an amount of 0.1 to 30% by weight, preferably 1 to 15% by weight calculated on the fertiliser.
Som nitrogenholdige gjødningsmidler kommer såvel mineralske som også organiske gjødningsmidler på tale, hvorved når det gjelder de mineralske nitrogengjødningsmidler, kan anvendes alle ammoniumsalter, som f.eks. ammoniumnitrat eller ammoniumsulfat, såvel ammoniakk eller urea både i gjødningsmid-ler som inneholder et næringsstoff som også i gjødningsmidler som inneholder flere næringsstoffer. Blant de organiske gjødnings-midlene skal eksempelvis nevnes kloakkvann (Giille) , gjødselvann, klokakkslam og lignende. Nitrogen-containing fertilizers include both mineral and organic fertilizers, whereby when it comes to the mineral nitrogen fertilizers, all ammonium salts can be used, such as e.g. ammonium nitrate or ammonium sulphate, as well as ammonia or urea both in fertilizers that contain one nutrient and also in fertilizers that contain several nutrients. Among the organic fertilisers, mention should be made, for example, of sewage water (Giille), manure water, sewage sludge and the like.
Anvendelsen av midlet ifølge oppfinnelsen er på grunn av dets gode anvendelsesmuligheter uproblematisk. Det er like godt egnet for faststoff- som også for flytende gjødsel. The use of the agent according to the invention is unproblematic due to its good application possibilities. It is equally suitable for solid as well as liquid fertiliser.
For fremstilling av faststoffgjødsel utdoseres det nitrifikasjonshemmende middel ifølge oppfinnelsen til gjødnings-midlene med de vanlige innretninger og blandes med disse, henholdsvis granuleres, "prilles" eller presses sammen. Også ved tilblandingen av midlet ifølge oppfinnelsen til flytende gjødsel (i form av løsninger eller suspensjoner) forekommer som regel ingen problemer. Tilblandingen kan foregå under fremstillin-gen av gjødningsmiddelløsningen henholdsvis -suspensjonen som også etterpå. Dessuten egner midlet ifølge oppfinnelsen seg fremragende for fremstilling av en vandig suspensjon, som kan utbringes med de vanlige plantemiddelsprøyter. Herved kan anvendelsen kombineres med utbringelsen av plantebeskyttelses-og skadebekjempningsmidler. For the production of solid fertiliser, the nitrification-inhibiting agent according to the invention is dosed to the fertilisers, using the usual devices and mixed with these, respectively granulated, "prilled" or pressed together. Also, when the agent according to the invention is mixed into liquid fertilizer (in the form of solutions or suspensions), no problems usually occur. The addition can take place during the preparation of the fertilizer solution or the suspension as well as afterwards. Moreover, the agent according to the invention is excellently suited for the production of an aqueous suspension, which can be applied with the usual plant sprayers. In this way, the application can be combined with the application of plant protection and pest control agents.
De nitrifikasjonshemmende midler ifølge foreliggende oppfinnelse gjør det mulig å senke mengden anvendt aktivt stoff betraktelig for samme virksomhet hhv. virkningsvårighet sammen-lignet- med enkeltbestanddelene. Da alle bestanddelene har en lav toksisitet og ikke etterlater betenkelige rester i jorden, egner det foreslåtte middel seg på fremragende måte for praktisk anvendelse. The nitrification-inhibiting agents according to the present invention make it possible to reduce the amount of active substance used considerably for the same activity or effectiveness compared to the individual components. As all the components have a low toxicity and do not leave any questionable residues in the soil, the proposed agent is eminently suitable for practical use.
De etterfølgende eksempler skal forklare oppfinnelsen nærmere, uten imidlertid å begrense den til disse. The following examples shall explain the invention in more detail, without, however, limiting it to these.
Eksempel 1Example 1
I et inkuberingsforsøk ble 100 g jord (sandholdig leire, pH 7,2) blandet med 20 mg urea-nitrogen og følgende mengder aktive stoffer: In an incubation experiment, 100 g of soil (sandy clay, pH 7.2) was mixed with 20 mg of urea nitrogen and the following amounts of active substances:
Forsøk 1 = 1,5 mg dicyandiamid (DCD)Trial 1 = 1.5 mg dicyandiamide (DCD)
Forsøk 2 = 1,5 mg guanylthiourea (GTH)Trial 2 = 1.5 mg guanylthiourea (GTH)
Forsøk 3 = 1,5 mg DCD + 1,5 mg GTHTrial 3 = 1.5 mg DCD + 1.5 mg GTH
Som kontroll tjente samme ureatilsetning til jorden, imidlertid uten aktivt stoff. Jorden ble inkubert i 0,5 1 plastflasker ved 60 % vannkapasitet og 20° C. Etter en inkuberingstid på 8, 12 og 16 uker ble innholdet av nitratnitrogen i jorden bestemt og fra dette ble nitrifikasjonshemmingen beregnet i % ifølge følgende formel: As a control, the same urea addition to the soil, however without active substance, served. The soil was incubated in 0.5 l plastic bottles at 60% water capacity and 20° C. After an incubation period of 8, 12 and 16 weeks, the content of nitrate nitrogen in the soil was determined and from this the nitrification inhibition was calculated in % according to the following formula:
Nitrifikasjonshemming Nitrification inhibition
a = nitrat-N-innhold i kontrollen a = nitrate-N content in the control
