    COMPOSITIONS OF ENCRAIS CONTAINING AN ACID-RESISTANT UREASE INHIBITOR TIN
    CROSS REFERENCE TO RELATED DEMAND
    This application claims a priority over US Provisional Application No. 62/266281 filed December 11, 2015, which is incorporated herein by reference in its entirety.
    TECHNICAL AREA
    The present invention relates to novel acid-resistant fertilizer compositions comprising a source of urea containing a particulate urease inhibitor, a particulate acid fertilizer and a basic component, as well as methods of making and using the compositions. acid resistant fertilizer.
    BACKGROUND
    Nitrogen losses due to ammonia volatilization occur with urea or urea-based fertilizers, particularly due to the rapid hydrolysis of urea on or near the soil surface by natural urease enzyme. A urea inhibitor such as N-alkylphosphoric triamide or N-alkylthiophosphoric triamide (especially N- (n-butyl) thiophosphoric triamide, NBPT) can slow enzymatic decomposition of urea by inhibition of the enzyme. urease. This is an effective way to manage ammonia nitrogen losses from fertilizers containing urea and applied to a surface.
    An N-alkylphosphoric triamide urease inhibitor or N-alkylthiophosphoric triamide such as NBPT can be applied to a granular fertilizer formulation by first mixing the concentrated solution of the N-alkylthiophosphoric triamide which is dissolved in a solvent such as the glycol or a glycol derivative or a mixed solvent of a glycol or a glycol derivative and a liquid amide. (See U.S. Patent No. 5,698,003). Alternatively, an N-alkylphosphoric triamide urease inhibitor or N-alkylthiophosphoric triamide such as NBPT can be introduced into the urea melt to form an incorporated urea fertilizer (see WO 2015/027244). In addition, a highly concentrated dry formulation of NBPT such as the AGROTAIN® DRI-MAXX nitrogen stabilizer, which can adhere to the urea granules without adding additional moisture to the mixture, can be used to treat the urea granules to to also make a urea containing NBPT. (See U.S. Patent No. 9,034,072).
    Although an N-alkylphosphoric triamide or N-alkylthiophosphoric triamide such as NBPT is reasonably stable under standard storage conditions such as ambient temperature and neutral pH, it is well known that acidic conditions can lead to the rapid disappearance of NBPT. . See, for example, Apparent persistence of N- (N-butyl) thiophosphoric triamide is greater in alkaline soils. Engel et al., Soil Science Society of America Journal (2013), 77 (4), 1424-1429.
    SUMMARY OF THE INVENTION The main object of the present invention is to provide a stable and economical fertilizer composition which comprises a source of particulate urea containing a urease inhibitor, a particulate acid fertilizer such as phosphate or sulfate fertilizer or a combination thereof, and a suitable basic component which is used to treat either the urea source containing a particulate urease inhibitor or the particulate acid fertilizer or both, independently, the impact acidic characteristics of the particulate acid fertilizer on the urease inhibitor may be substantially reduced to provide improved shelf life to the acid-sensitive urease inhibitor such as NBPT.
    Urea fertilizers containing a urease inhibitor and phosphate or sulphate fertilizers can provide various nutrients to the soil and / or plants to provide one or more nutrients essential for plant growth. Although fertilizers comprising various nutrients can be applied separately to soils or plants, it may be advantageous to prepare, package, transport, store and / or use a single fertilizer composition.
    Some fatteners may, however, be incompatible with each other for a variety of reasons. For example, the shelf life of certain urease inhibitors such as NBPT could be significantly shortened under acidic conditions when urea fertilizer granules containing a urease inhibitor are mixed with an acidic mixing partner such as monoammonium phosphate (MAP), diammonium phosphate (DAP), ammonium sulphate, ammonium hydrogen sulphate or any acidic fertilizer which includes, for example, any form of sulphate or phosphate. It has been observed that a urease inhibitor such as NBPT can decompose almost completely within one to two weeks after mixing urea containing NBPT with one or more fatty acids such as MAP.
    Surprisingly, certain basic components applied to the surface of particulate acid fertilizers impart unexpected stability to NBPT when NBPT treated urea is mixed with the acidic ingredients treated with the basic component. Examples of acidic fertilizers that can be treated include MAP, DAP, ammonium sulfate, phosphate rock or Micro-Essentials® SZ (MESZ (12-40-0-10S-lZn). Basic to treat an acidic fertilizer can generally not be a good approach because acid and base can react, even when they are both in solid form.
    Alternatively, the same surprising advantages are obtained by treating the surface of the fertilizer containing a particulate urease inhibitor with a certain basic component. This composition treated with a basic component can also offer a surprisingly longer shelf life of the NBPT when mixed with an untreated acid fertilizer.
    Thus, by using a basic component to treat the surface of a particulate urea source containing a urease inhibitor or a particulate acid fertilizer, or both independently, the present invention provides novel fertilizer compositions. containing an acid-resistant urease inhibitor that may provide a longer shelf life for an acid-sensitive urease inhibitor such as NBPT.
    In one embodiment, the present invention provides a particulate fertilizer composition comprising a basic component and a particulate acidic fertilizer having a surface, the surface of the particulate acid fertilizer being treated with the basic component. The particulate acid fertilizer that is treated with the basic component provides 14-1500 days of half-life under laboratory-accelerated NBPT stability test conditions for a urease inhibitor when the particulate acid fertilizer treated with the component basic is mixed with a source of particulate urea containing a urease inhibitor.
    In another embodiment, the present invention provides a particulate fertilizer composition comprising a basic component and a source of particulate urea containing a urease inhibitor having a surface, the surface of the particulate urea source containing an inhibitor urease being treated with the basic component.
    The source of particulate urea containing a urease inhibitor that is treated with the basic component provides 14-1500 days of half-life under laboratory accelerated NBPT stability test conditions for the urease inhibitor when the A source of particulate urea containing a urease inhibitor treated with the basic component is mixed with a particulate acid fertilizer.
    In another embodiment, the present invention provides an acid resistant fertilizer composition comprising i). a particulate acid fertilizer having a surface; ii). a source of particulate urea containing a urease inhibitor having a surface; and iii). a basic component, wherein the surface of at least one of i) or ii) is treated with iii).
    The acid-resistant fertilizer composition provides 14 to 1500 days of half-life under laboratory accelerated NBPT stability test conditions for the urease inhibitor.
    DETAILED DESCRIPTION OF THE INVENTION
    As used herein, the terms below have the following meaning, unless otherwise stated: "Treated with the basic component", "treated with a basic component", or any term relating to the mode of treatment on the surface of a particulate acid fertilizer or urea-containing particulate urea source in the present invention means that a suitable basic component is added and adhered to the surface of said particulate acid fertilizer or said source of particulate urea containing a urease inhibitor to provide sufficient protection to the urease inhibitor such as NBPT. Although it is desirable to cover as much of an acidic fertilizer as possible with a suitable basic component, if the NBPT is sufficiently protected or the decomposition rate of the NBPT is sufficiently slowed down, the actual percentage of the surface covered with a particulate fertilizer can range from 10% to 100%, 20% to 100%, 30% to 100%, 40% to 100%, 50% to 100%, 60% to 100%. 70% to 100%, 80% to 100%, 90% to 100%, or 95% to 100%. The percentage of surface area covered in the present invention is primarily the percentage of the visible outer surface of the acid fertilizer particles rather than the total area, which may include the area of small pores within the fertilizer particle. particulate. "Half-life shelf life", or "half-life" of a urease inhibitor such as NBPT in the present invention refers to the amount of time required for the amount of urease inhibitor such as the NBPT is halved from its initial value prior to mixing particulate acid fertilizer and the particulate urea source containing a urease inhibitor. In the present invention, a fertilizer mixture whose half-life of the urease inhibitor is to be tested is stored in a sealed jar under ambient conditions after mixing the particulate acid fertilizer with the source of the fertilizer. particulate urea containing a urease inhibitor. The content of urease inhibitor is analyzed by high pressure liquid chromatography (HPLC), a technique which is known to those skilled in the art. In some situations, the half-life shelf life is high. At the time the data is collected, the urease inhibitor content is still greater than 50% of the initial urease inhibitor content. For such examples, the actual urease inhibitor content and days elapsed after mixing are recorded. For example, the NBPT content of Example 33 of the present invention was half of the initial 91 day content (half-life). The half-life of 91 days is therefore recorded as the half-life of the NBPT. The NBPT content in Example 34 of the present invention is 71% at 28 days when the data is collected. The value of 71% is well above 50%. Actual days after mixing (28 days) and residual NBPT (71%) are indicated.
    There has long been a need to develop fertilizer compositions containing an acid-resistant urease inhibitor that provides multiple nutrients such as nitrogen, phosphate and sulfate. NBPT is the most commonly used urease inhibitor to reduce nitrogen losses due to the volatilization of ammonia for urea or urea-based fertilizers. However, the NBPT is very sensitive to acidic conditions. The most widely used phosphate and sulphate fertilizers are often very acidic and they break down the NBPT very quickly if they are mixed with urea sources containing NBPT. It has been observed that NBPT can decompose almost completely within one to two weeks after mixing urea containing NBPT with one or more acidic fertilizers such as MAP.
    Previous efforts to reduce the problem have been attempted to treat particulate fertilizers with coating materials such as wax or polymeric coatings. To date, no satisfactory multi-nutrient composition containing acid-resistant NBPT has been disclosed. Therefore, the main objective of this invention is to develop a fertilizer composition containing economical and acid-resistant NBPT to meet this long-standing need.

    Examples 17 to 32 of Table 2 are prepared essentially as Example 16.
    Table 2:
    *: The order of coating is reversed. The wax is first added at 65 ° C for a 10-minute coating, then add Al (OH) 3 and mix for another 5 minutes.

    Examples 36 to 43 of Table 4 are prepared essentially as Example 35.
    Table 4:
    NBPT Stability Test The objective of the NBPT Stability Test is to determine whether a certain basic component may confer on NBPT an extended shelf life after ATU is mixed with a particulate acid fertilizer, when the at least one of the ATU or particulate acid fertilizer is treated with the basic component. One or more layers of a variety of wax may optionally be applied. The half-life of the NBPT is used to show the stability performance of the NBPT. If the NBPT content is still more than half of the initial content on the day of the data collection, the actual NBPT content and the days elapsed since the preparation of the mixture are recorded. For example, if the NBPT content is 65% at 50 days after mixing the ATU and particulate acid fertilizer, "65% to 50 days" is used to indicate the performance. Mix in a 50/50 ratio a sample of ATU and a sample of particulate acid fertilizer in a container and shake vigorously to obtain a visually homogeneous mixture. The moment when the homogeneous mixture is obtained is recorded as time zero.
    In the present invention, if the ATU sample and the particulate acid fertilizer sample each make 75 g, a container of about 240 mL (8 ounces) can be used. If the ATU sample and particulate acid fertilizer sample are each 150 g, a container of approximately 470 mL (16 ounces) may be used. The container is opened at regular intervals of one week, two weeks, one month, two months, three months, six months, nine months, twelve months, or at other times in time as needed. The time between each opening and closing is approximately 1 to 2 minutes. In actual situation, the "container" may be 600 kg or 1000 kg bulk bags with a hermetically sealed plastic underlay prior to use. Since the container is constantly open in the NBPT stability test method of the present invention, oxygen and moisture can have a significant impact with respect to actual storage conditions. The NBPT stability test of the present invention causes acceleration over actual storage conditions. For example, when ammonium sulfate from the United Kingdom is mixed with ATU and stored under actual storage conditions, the NBPT has a half-life of 12 to 18 months. When exactly the same ammonium sulphate and ATU are mixed under the stability test conditions in a small sealed container that is opened and closed frequently, the half-life shelf life of the NBPT is about 38 days. Therefore, the stability test of the NBPT of the present invention can also be called a "laboratory accelerated NBPT stability test".
    To test the residual NBPT content of a sample of ATU, about ten grams of the mixture of the container are taken on the day of the test. The green pellets (ATU sample) are separated from the particulate acid fertilizer. The green granules (ATU sample) are then subjected to HPLC analysis to determine the NBPT content (recorded as ppm of NBPT, converted to% based on the initial NBPT). The HPLC test is carried out on a standard Cig column with a 75% water and 25% acetonitrile solution. UV absorbance is measured at 214 nm. Examples 44 to 90 are tested based on the test method described above.
    Example 44
    Fertilizer composition composed of ATU and MgO-treated DAP, and NBPT stability performance
    Place Example 1 in a glass jar containing AGROTAIN stabilized urea (ATU) (660 ppm NBPT, initial NBPT concentration before mixing with DAP) in a weight ratio of 50/50 ( 75 g of each component). Secure the lid and shake the mixture in the jar until smooth. The half-life shelf life of the NBPT is 140 days.
    Examples 45 to 75 of Table 5 are prepared essentially as Example 44.
    Table 5:
    Example 76
    Add Example 3 (470 ppm NBPT) to untreated DAP at 1/1 ratio (75 g / 75 g). Secure the lid and shake the mixture until it is visually homogeneous. The half-life shelf life of the NBPT is 94 days.
    Examples 77-90 of Table 6 are prepared essentially as Example 76.
    Table 6:
    Under similar test conditions, the half-life of NBPT for certain samples not treated with a basic component is given in Table 7:
    Table 7: Half-life shelf life of NBPT for mixtures without basic component
    It is observed from the test results in Table 7 that the ATU sample not mixed with an acidic fertilizer has the longest shelf life of the longest NBPT. When the ATU sample is mixed with an acid fertilizer, the half-life shelf life drops significantly. For example, the half-life of NBPT decreases by about 96% from 214 days to 9 days when the ATU sample is mixed with MAP. When the MAP is treated with a suitable basic component such as MgO in Example 56, the stability of NBPT is significantly improved to 60% NBPT at 91 days.
    Identical acidic fertilizers from different sources may give rise to very different half-lives of NBPT. For example, an ammonium sulphate from the United Kingdom (UK) has a shelf life with a half-life of NBPT longer than 100% (38 days) compared to a Honeywell ammonium sulphate in the United States. United (18 days).
    Although some examples may show a shorter half-life of the NBPT, this does not necessarily mean that the basic component is not suitable for the treatment of particulate fertilizers. In one example, the calcium stearate treated DAP of Example 50 has a half-life of NBPT of only 12 days, whereas on the contrary the calcium stearate treated ATU of Example 77 provides a NBPT half-life of 28 days. In another example, the half-life of the NBPT for the KOH-treated ATU of Example 85 is nil (more than half breaks down on the first day), the half-life of the NBPT for the DAP treated by the KOH of Example 69 is 22 days.
    Examples 91 to 98 are prepared for the NBPT stability test. Examples 99 to 106 relate to example examples stored under normal industrial storage conditions, instead of the "laboratory accelerated NBPT stability test conditions".
    Example 91
    Diammonium phosphate treated with magnesium oxide Place 6000 kg of diammonium phosphate (DAP) in a rotary drum mixer and then add 16.5 kg of powdered magnesium oxide (MgO) to the drum mixer. The components are mixed for 6 minutes at room temperature. The weight percent of MgO of the MgO treated DAP is about 0.275% of the total weight.
    Examples 92 to 94 of Table 8 are prepared essentially as Example 91.
    Table 8:
    Example 95
    Diammonium phosphate treated with magnesium oxide Place 6000 kg of diammonium phosphate (DAP) in a rotary vertical screw mixer and add 16.5 kg of powdered magnesium oxide (MgO) to the screw mixer endless vertical rotary. The components are mixed for 6 minutes at room temperature. The weight percent of MgO of the MgO treated DAP is about 0.275% of the total weight.
    Examples 96 to 98 of Table 9 are prepared essentially as Example 95.
    Table 9:
    NBPT stability test under normal industrial storage conditions The objective of the NBPT stability test is to determine if a certain basic component may confer on the NBPT an extended shelf life after ATU is mixed with a particulate acid fertilizer, when at least one of ATU or particulate acid fertilizer is treated with the basic component. One or more layers of a variety of wax may optionally be applied. The half-life of the NBPT is used to show the stability performance of the NBPT. If the NBPT content is still more than half of the initial content on the day of the data collection, the actual NBPT content and the days elapsed since the preparation of the mixture are recorded. For example, if the NBPT content is 65% at 50 days after mixing the ATU and particulate acid fertilizer, "65% to 50 days" is used to indicate the performance. Mix in a 50/50 ratio a sample of ATU and a sample of particulate acid fertilizer in a blender and mix the mixture for a few minutes then place the mixture in a bag without waiting. The moment when the mixture is placed in the bag is recorded as time zero. The sample is then removed from the bag after a period of time for the NBPT concentration test.
    Example 99
    Place Example 91 in a rotary vertical screw mixer containing AGROTAIN stabilized urea (ATU) (640 ppm NBPT, initial NBPT concentration before mixing with DAP) in a weight ratio of 50/50 (3000 kg of each component). The components are mixed for about 6 minutes at room temperature before being bagged. The NBPT concentration compared to the initial NBPT concentration was 53% at 217 days and 17% at 315 days.
    Examples 100 to 106 of Table 10 are prepared essentially as Example 99.
    Table 10:
    The above values are based on the analysis of the ATU samples and do not take into account the transfer of NBPT to the DAP.
    It is observed from Table 10 that the NBPT concentration of Examples 99 to 106 remains at least 70% of the initial NBPT concentration at 315 days when the weight percent of MgO in the MgO-treated DAP is greater than or equal to at 0.55%. When the weight percentage of MgO in the MgO-treated DAP is 0.275% as in Examples 99 and 103, the NBPT concentration is always greater than 50% of the initial NBPT concentration at 217 days. The data show that the MgO-treated DAP of Examples 99-106 exhibits surprisingly high and prolonged stability of NBPT under normal industrial storage conditions.
    Spreading Test The purpose of the spreading test is to evaluate whether the MgO-treated DAP fertilizer disclosed in the present invention may exhibit significant variation from the unmaged MgO-treated DAP. Based on European Standard EN13739-2 for solid fertilizer distributors, the value of the coefficient of variation (CV) is used to evaluate the variation. If the CV is greater than 20% it is not acceptable. The CV value between 15% and 20% is considered mediocre. The CV value between 10% and 15% is considered good. The CV value of less than 10% is considered excellent.
    Production scale samples prepared according to the method of Example 98 are used for the spreading test. The proper functioning of the spreaders is checked. Fertilizer is analyzed with a Vicon sieve with compartments of size 0 to 2, 2 to 3.3, 3.3 to 4.75 and more than 4.75 mm. A Bogballe force tester measures kg-force to grind a granule / pearl. A one-liter graduated cylinder and a digital scale are used for bulk density in kg / L. Collection trays of 50 cm x 50 cm are spaced at intervals of one meter over the entire spreading width. A motorized hopper with trays "folded" halfway. Fertilizer is transferred to tubes to visually assess its distribution.
    The manufacturer / model of spreader is Amazone ZA-M. The type of disc / fin is OM 24-36. The width of the spreader is 24 meters. The height of the spreader is 80 cm from the side of the disc. The inclination is zero degrees. The PTO / Disk speed is 540 rpm. The application rate is 200 kg / Ha. The speed of advance is 10 km / h.
    The CV value for the MgO treated DAP is 6.68% (n = 2, CV1 = 6.48%, CV2 = 6.88%). The CV value for the untreated DAP is 9.49% (n = 2, CV1 = 7.95%, CV2 = 11.03%).
    It is observed that the CV value for the second MgO treated DAP application is almost unchanged (less than 6%) while the CV value for the second untreated DAP application test increases by 39%. %.
    Thus, the MgO-treated DAP disclosed in the present invention gives excellent results in the spreading test over untreated DAP fertilizer.
    The present invention provides fertilizer compositions containing an acid-resistant and economical urease inhibitor that can provide multiple nutrients such as nitrogen, phosphate and sulfate to soil and / or plants.
    It will be understood that while the invention has been specifically described with reference to particular means and embodiments, skilled artisans will appreciate that the present invention is not limited to the details disclosed in the foregoing description. The present invention also extends to all equivalents, and to the various changes and modifications that may be made to the invention without departing from the spirit and scope thereof.
