    This invention relates to ammonium nitrogen nitrification inhibitors in mineral and organic fertilizers in soil.
    The purpose of the invention is to increase the effectiveness of the inhibitor.
    Example 1. In the experiment with thermostatting, 100 g of soil (sandy sap, pH 7E2) is mixed with 20 mg of urea-nitrogen and the following quantities of active substance are mixed in: experiment 1 - 1s 5 mg of dicyandiamide (DSD), experiment 2 - 1, 5 mg guanyl thiourea (GTH), experience 3 - 1.5 mg DSD + 1.5 mg GTH.
    The control is the same dose of urea for the soil, but without active
    substances. Soils thermostatic in plastic bottles with a volume of 0.5 liters at a water content of 60% and at 20 ° C. Pos-; After thermostating for 8, 12, and 16 weeks, the content of nitrate nitrogen in the soil is determined, and hence the inhibition of nitrification (%) is calculated using the following formula:

    The results are shown in Table. one.
    Overall, the use of dicyandiamide and guanyl thiourea showed inhibition of nitrification by 7.22 or 34% more than the compound inhibition of individual components.
    Example 2. The experiment was carried out as described in example 1, but with ammonium sulfate as a source of nitrogen.
    The results are shown in Table 2.
    The general use of dicyandiamide and guanyl thiourea showed a slowdown of nitrification by 9.18 or 31% more than the compound of inhibition of the individual
    yy components.
    EXAMPLE 3 The experiments were carried out as described in Example 2, with different combinations of dicyandiamcd and vanyl thiourea. After thermostati- 20 ovani for 12 weeks. combinations of the active substance exceeded the combined inhibition of the individual components by the following amount,%:

The experiment was carried out as 30 described in Example 1, but with ammonium thiosulfate (A.TS) as the second component of the combination of active substances. The duration of the thermostatic bath was 4.6 and 8 weeks. 35 The results are shown in Table. 3. The general use of dicyandiamide and ammonium thiosulfate showed that nitrification was inhibited by 3.8 or 15% more than the braking compound of the individual components.
    EXAMPLE 5 The experiment was carried out as described in example 1, but with a three-component combination of a pentone combination consisting of dicyandiamide (ADD), guanylthiourea (GTH) and ammonium thiosulfate (ATS). “12 or 16 weeks.
    The results are shown in Table. D. A three-component combination of di 50 cyandiamide, guanyl thiourea and ammonium thiosulfate showed inhibition of nitrification by 19, 35 or 40% more than the braking compound of individual
    components.55
    Example 6. The experiment was carried out as described in example 15 and the ammonium polyphosphate was added to various combinations of the active substance.

    The addition of ammonium polyphosphate increased the inhibition of nitrification by 9 or 13%.
    Example. The test was carried out as described in Example 2 with ammonium sulphate as a nitrogen source, the soil was kept under constant conditions (temperature 20 ° C and water content 60%) for 12 weeks and tested a mixture consisting of DSD and ATS with polyphosphate ammonium or without it.

    PRI me R 8. In the experiment in a vessel (7 kg of soil in a Mitscherlich vessel), the effect of the combination of active substances, consisting of diiacidimide (ADD) and guanylthiourea (GTH), on the washing out of nitrate after urea fertilization was investigated. During the first three weeks after fertilization, the following amounts (%) of urea applied as fertilizer were washed out:
    Mo4f wine without active substance 48.2
    Urea with 10% DSD - N 19.9 10% GTH - N 14.2

    Example 9. When tested under field conditions, the action was checked.
    combinations of active substances consisting of dicyandiamide (dsid), guanyl thiourea (GTH) to ammonium thiosulfate (ATS) on. sugar beet harvest. A combination of active substances was used with. a solution of ammonium nitrate urea (AHL) in the amount of 200 kg / ha (including the N active substance) before sowing sugar beet. ; The yield data is given in table.5.
    The nitrification inhibitor can be used either alone or in combination with nitrogen-containing fertilizers.
    If it is used without fertilizers, then a consumption rate of 0.1 to 300 kg / ha, preferably from 1 to 60 kg / ha, is recommended, and it can be used either before applying the fertilizer, simultaneously with applying the fertilizer or: after applying the fertilizer .
    On the contrary, if the inhibitor nj of the invention is used in combination with a nitrogen-containing fertilizer, the nitrification of which it must inhibit, then it is advisable to use in an amount of from 0.1 to 30% by weight, preferably from 1 to 15% by weight, calculated on the basis of fertilizer.
    The proposed nitrification inhibitor allows for the same efficacy or duration of action to significantly reduce the consumption of the active substance as opposed to individual components, since all the components have a slight toxicity.
