Den foreliggende opfindelse angår et middel til hæmning af ni-trifikationen af ammoniumnitrogen især i mineralske og organiske gødningsmidler i jordbunden.The present invention relates to an agent for inhibiting the nitrification of ammonium nitrogen especially in soil mineral and organic fertilizers.
Det er kendt, at ammoniumnitrogen i jordbunden forholdsvis 5 hurtigt omdannes af bakterier til nitratnitrogen. Denne nitri-fikation påvirkes afgørende af temperatur, jordbundsfugtighed, pH-værdi samt biologisk aktivitet i jordbunden.It is known that ammonium nitrogen in the soil is rapidly converted by bacteria to nitrate nitrogen. This nitrification is significantly affected by temperature, soil moisture, pH and soil biological activity.
Da nitratnitrogen i modsætning til ammoniumnitrogen ikke fastholdes af jordbundspartikler, kan det let udvaskes ved nedbør 10 især på let gennemtrængelig jord. På denne måde går nitrogenet tabt som vigtigt næringsstof for planterne. Derudover kan der ske nitratberigelse i grundvand eller drikkevand, hvilke under nogle omstændigheder kan føre til sundhedsmæssige problemer.Since nitrate nitrogen, unlike ammonium nitrogen, is not retained by soil particles, it can be easily washed out by rainfall 10, especially on easily permeable soil. In this way, the nitrogen is lost as an important nutrient for the plants. In addition, nitrate enrichment can occur in groundwater or drinking water, which in some circumstances can lead to health problems.
Ved siden af udvaskningstab optræder der også betydelige luft-15 formige nitrogentab ved denitrifikation af nitratnitrogenet.In addition to leaching losses, significant gaseous nitrogen losses also occur during denitrification of the nitrate nitrogen.
Ved tilsætning af nitrifikationshæmmende midler kan dette nitrogentab formindskes, og udnyttelsen af nitrogenholdige gødningsstoffer forbedres afgørende.By adding nitrification inhibitors, this nitrogen loss can be reduced and the utilization of nitrogenous fertilizers significantly improved.
Derfor er der til dette formål udviklet en række nitrifikati-20 onshæmmende midler f.eks. på basis af pyridinderivater, anilinderivater, chlorderivater eller svovlderivater.Therefore, a number of nitrification inhibitors have been developed for this purpose e.g. on the basis of pyridine derivatives, aniline derivatives, chlorine derivatives or sulfur derivatives.
Disse forbindelser udviser dog i praksis forskellige ulemper f.eks. høj flygtighed, som nødvendiggør en kompliceret indføring i jordbunden. Desuden er disse forbindelser i reglen tok-25 siske og/eller efterlader toksiske rester i jorden. Ud fra et økologisk synspunkt kan derfor kun anbefales sådanne kendte nitrifikationshæmmende stoffer til praktisk anvendelse, som hverken er toksiske eller giver remanensproblemer. Hertil hører især nitrogenholdige forbindelser, som f.eks. dicyandi-30 amid, guanylthiourinstof eller ammoniumthiosulfat, som i jordbunden nedbrydes fuldstændigt til nitrogen, der står til rådighed for planterne. En ulempe ved disse forbindelser f.eks.However, in practice these compounds exhibit various disadvantages e.g. high volatility, which necessitates a complicated introduction into the soil. In addition, these compounds are generally toxic and / or leave toxic residues in the soil. Therefore, from an ecological point of view, only such known nitrification inhibitors can be recommended for practical use which are neither toxic nor cause residue problems. These include, in particular, nitrogenous compounds such as e.g. dicyandiamide, guanylthiourea, or ammonium thiosulfate, which is completely degraded in the soil to nitrogen available to the plants. A disadvantage of these compounds e.g.
2 DK 167061 B1 i sammenligning med pyridinderivater er den ringere virkning eller varighed af virkningen. De må derfor anvendes i større mængder, hvorved der opstår ikke blot finansielle men også en række anvendelsestekniske problemer.In comparison with pyridine derivatives, the lower effect or duration of the effect is inferior. They must therefore be used in large quantities, which results in not only financial but also a number of technical problems.
5 Til grund for den foreliggende opfindelse var derfor den opgave at udvikle et nitrifikationshæmmende middel, som ikke udviser de nævnte ulemper ved den kendte teknik, men som har en udmærket virkning og gode anvendelsesmuligheder, og som både i toksikologisk og i remanensmæssig henseende er uden problemer.Therefore, the object of the present invention was to develop a nitrification inhibitor which does not exhibit the aforementioned disadvantages of the prior art, but which has an excellent effect and good applications, and which is toxic in both toxicological and remanufacturable terms. .
10 Denne opgave blev løst ifølge opfindelsen med et nitrifika-tionshæmmende middel, som er ejendommelig ved, at det består af a) dicyandiamid og b) guanylthiourinstof og/eller ammoniumthiosulfat 15 samt om ønsket ammoniumphosphat.This problem was solved according to the invention with a nitrification inhibitor, which is characterized in that it consists of a) dicyandiamide and b) guanylthiourea and / or ammonium thiosulfate 15 and, if desired, ammonium phosphate.
Det har nemlig overraskende vist sig, at midlet ifølge opfindelsen bevirker en væsentlig mere intensiv og længere varende hæmning af nitrifikationen, end der fås ved en addition af hæmningsvirkningerne af enkeltkomponenterne a) og b) .Surprisingly, it has been found that the agent of the invention causes a significantly more intense and longer lasting inhibition of nitrification than is obtained by the addition of the inhibitory effects of the single components a) and b).
20 Denne synergistiske virkning, der også er meget udpræget ved kombination af flere enkeltkomponenter, kunne på ingen måde forudses.20 This synergistic effect, which is also very pronounced by combining several single components, could in no way be foreseen.
Det nitrifikationshæmmende middel ifølge opfindelsen består af komponenterne a) , nemlig dicyandiamid og mindst én yderligere 25 komponent b) valgt af gruppen guanylthiourinstof og ammoniumthiosulfat samt derudover om ønsket ammoniumphosphat, således at det består af indtil fire enkeltkomponenter.The nitrification inhibitor of the invention consists of components a), namely dicyandiamide and at least one additional component b) selected from the group of guanylthiourea and ammonium thiosulfate and, additionally, if desired, ammonium phosphate, so that it consists of up to four single components.
Forholdet mellem enkeltkomponenteme indbyrdes kan variere inden for vide grænser, hvorved den synergistiske virkning DK 167061 B1 3 naturligvis er mere eller mindre udpræget.The relationship between the individual components may vary within wide limits, whereby the synergistic effect of DK 167061 B1 3 is, of course, more or less pronounced.
Med tokomponentsys terner må blandinger bestående af 20 til 80 vægt% dicyandiamid og 20 til 80 vægt% guanylthiourinstof anses for foretrukne.With two-component systems, mixtures of 20 to 80% by weight of dicyandiamide and 20 to 80% by weight of guanylthiourea should be considered preferred.
5 Som trekomponent sys terner har især blandinger bestående af 20 til 70 vægt% dicyandiamid, 20 til 70 vægt% ammoniumthiosulfat, 10 til 60 vægt% ammoniumphosphat vist sig særligt egnede.In particular, as three-component systems, mixtures of 20 to 70% by weight of dicyandiamide, 20 to 70% by weight of ammonium thiosulfate, 10 to 60% by weight of ammonium phosphate have proved particularly suitable.
10 Endelig kan midlet ifølge opfindelsen anvendes som firekompo-nentsystem, hvorved det fortrinsvis består af 20 til 60 vægt% dicyandiamid, 20 til 60 vægt% guanylthiourinstof, 10 til 50 vægt% ammoniumthiosulfat, 15 10 til 50 vægt% ammoniumphosphat.Finally, the agent of the invention can be used as a four-component system, preferably consisting of 20 to 60% by weight dicyandiamide, 20 to 60% by weight guanylthiourea, 10 to 50% by weight ammonium thiosulfate, 15 to 50% by weight ammonium phosphate.
Ved ammoniumphosphat inden for den foreliggende opfindelses rammer skal forstås ammoniumholdige phosphatforbindelser, især ammoniumdihydrogenphospat, diammoniumhydrogenphosphat samt am-moniumpolyphosphat.Ammonium phosphate within the scope of the present invention is understood to include ammonium phosphate compounds, especially ammonium dihydrogen phosphate, diammonium hydrogen phosphate, and ammonium polyphosphate.
20 Det nitrifikationshæmmende middel ifølge opfindelsen kan udbringes både alene og i kombination med nitrogenholdige gødningsmidler.The nitrification inhibitor of the invention can be applied both alone and in combination with nitrogenous fertilizers.
Hvis det anvendes uden gødningsmidler anbefales en mængde 0,1 til 300 kg/ha, fortrinsvis 1 til 60 kg/ha, idet udbringningen 25 kan ske enten før, samtidig med eller efter gødskningen.Hvis midlet ifølge opfindelsen derimod anvendes i kombination med det nitrogenholdige gødningsmiddel, hvis nitrifikation det skal hæmme, anvendes det hensigtsmæssigt i en mængde på 0,1 4 DK 167061 B1 til 30 vægt%, fortrinsvis 1 til 15 vægt% beregnet på gødnings-midlet.If used without fertilizers, an amount of 0.1 to 300 kg / ha, preferably 1 to 60 kg / ha, is recommended, since application 25 can be carried out either before, simultaneously with or after fertilization. On the contrary, if the agent according to the invention is used in combination with the nitrogenous fertilizer, if nitrification 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 fertilizer.
Som nitrogenholdige gødningsmidler kan der anvendes både mineralske og organiske gødningsmidler, idet der som mineralske 5 nitrogengødningsmidler kan anvendes alle ammoniumsalte som f.eks. ammoniumnitrat eller ammoniumsulfat samt ammoniak eller urinstof både i enkeltgødningsmidler og gødningsmidler med flere næringsstoffer. Ved de organiske gødningsmidler skal f.eks. forstås gylle, ajle, klaringsslam og lignende.As nitrogenous fertilizers, both mineral and organic fertilizers can be used, as as mineral fertilizers all ammonium salts such as e.g. ammonium nitrate or ammonium sulfate and ammonia or urea both in single fertilizers and fertilizers with several nutrients. In the case of the organic fertilizers, e.g. are understood slurry, eel, clearing sludge and the like.
10 Anvendelsen af midlet ifølge opfindelsen er uproblematisk på grund af dets gode anvendelsesmuligheder. Det er lige godt egnet til faststofgødninger og til flydende gødninger.The use of the composition according to the invention is unproblematic due to its good application potential. It is equally suitable for solid fertilizers and liquid fertilizers.
Til fremstilling af faststofgødninger doseres det nitrifika-tionshæmmende middel ifølge opfindelsen til gødningsmidlerne 15 med de sædvanlige apparater og blandes med disse eller bliver granuleret, prillet eller presset sammen med disse. Heller ikke ved iblanding af midlet ifølge opfindelsen i flydende gødninger (i form af opløsninger eller suspensioner) optræder der problemer. Iblandingen kan ske under fremstillingen af gød-20 ningsmiddelopløsningen eller -suspensionen og ligeledes bagefter. Derudover egner midlet ifølge opfindelsen sig fremragende til fremstilling af en vandig suspension, der kan udbringes med de sædvanlige plantemiddel sprøjter. Herved kan anvendelsen kombineres med udbringning af plantebeskyttelsesmidler og ska-25 dedyrsbekæmpel sesmidler.For the production of solid fertilizers, the nitrification inhibitor of the invention is dosed into the fertilizers 15 with the usual apparatus and mixed with them or granulated, prilled or pressed therewith. Problems do not occur even when admixing the composition of the invention in liquid fertilizers (in the form of solutions or suspensions). The mixture can be made during the preparation of the fertilizer solution or suspension and also afterwards. In addition, the agent according to the invention is well suited for preparing an aqueous suspension which can be applied with the usual herbal sprayers. Hereby, the application can be combined with the application of plant protection products and pest control agents.
Det nitrifikationshæmmende middel ifølge opfindelsen gør det muligt til samme virkning eller samme varighed af virkningen betydeligt at nedsætte den anvendte mængde virksomt stof sammenlignet med enkeltkomponenterne. Da alle komponenter har en 30 ringe toksicitet og ikke efterlader nogen betænkelige rester i jorden, egner midlet ifølge opfindelsen sig på fremragende måde til praktisk anvendelse.The nitrification inhibitor of the invention allows the same effect or duration of action to significantly reduce the amount of active ingredient used compared to the individual components. Since all components have a low toxicity and leave no questionable residue in the soil, the composition of the invention is well suited for practical application.

De følgende eksempler skal belyse opfindelsen nærmere uden at begrænse denne.The following examples will illustrate the invention in more detail without limiting it.

Efter en inkubationstid på 8, 12 og 16 uger blev indholdet af nitratnitrogen i jorden bestemt og heraf blev beregnet nitrifikationshæmningen i procent 15 efter følgende formel:10 As a control, the same addition of urea to the soil served, but without active substance. 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 15% nitrification inhibition was calculated according to the following formula:
Nitrifikationshæmning (%) = a - b x 100 a - c a = nitrat-N-indhold i kontrollen b = nitrat-N-indhold i forsøget 20 c = nitrat-N-indhold i jorden.Nitrification inhibition (%) = a - b x 100 a - c a = nitrate N content in the control b = nitrate N content in the experiment 20 c = nitrate N content in the soil.
