Description

This application is a National Stage application of International Application No. PCT/IB2014/062667, filed Jun. 27, 2014, which claims the benefit of International Application No. PCT/IB2013/055484, filed Jul. 4, 2013; International Application No. PCT/IB2013/055486, filed Jul. 4, 2013; and International Application No. PCT/IB2013/055483, filed Jul. 4, 2013.

FIELD OF THE INVENTION

This invention essentially relates to compositions with improved urease-inhibiting effect comprising (thio)phosphoric acid triamide and further compounds and the use of such compositions as additive or coating material for nitrogen-containing fertilizers.

DESCRIPTION OF THE PRIOR ART

Worldwide, the predominant and further-increasing amount of the nitrogen used for fertilizing is employed in the form of urea or urea-containing fertilizers. Urea itself, however, is a form of nitrogen which is absorbed very little if at all, being hydrolyzed relatively rapidly by the enzyme urease, which is present ubiquitously in the soil, to form ammonia and carbon dioxide. In this process, in certain circumstances, gaseous ammonia is emitted to the atmosphere, and is then no longer available in the soil for the plants, thereby lowering the efficiency of fertilization.

It is known that the degree of utilization of the nitrogen when using urea-containing fertilizers can be improved by spreading urea-containing fertilizers together with substances which are able to inhibit or decrease the enzymatic cleavage of urea (for a general review, see Kiss, S. Simihäian, M. (2002) Improving Efficiency of Urea Fertilizers by Inhibition of Soil Urease Activity, ISBN 1-4020-0493-1, Kluwer Academic Publishers, Dordrecht, The Netherlands). Among the most potent known urease inhibitors are N-alkylthiophosphoric acid triamides and N-alkylphosphoric acid triamides, which are described in EP 0 119 487, for example.

Additionally, mixtures of N-alkylthiophosphoric acid triamides such as N-(n-butyl)thiophosphoric acid triamide (NBPT) and N-(n-propyl)thiophosphoric acid triamide (NPPT) can be used. The mixtures and their preparation are described in US 2010/218575 A1, for example.

These urease inhibitors are described in U.S. Pat. No. 4,530,714, for example. In order for this class of compound to be able to act as a urease inhibitor, there must first be a conversion to the corresponding oxo form. That form reacts subsequently with the urease, causing its inhibition.

It is advisable to apply the urease inhibitors together with the urea onto or into the soil, since this ensures that the inhibitor comes into contact, together with the fertilizer, with the soil. The urease inhibitor may be incorporated in the urea by, for example, dissolving it into the melt prior to urea granulation or prilling. A process of this kind is described in U.S. Pat. No. 5,352,265, for example. A further option is to apply the urease inhibitor to the urea granules or prills, in the form of a solution, for example.

Corresponding processes for application, and suitable solvents, are described in US 2010/218575 A1, for example. Other suitable additives, for example amines selected from methyldiethanolamine, tetrahydroxypropylethylenediamine, trimethylaminoethylethanolamine, N,N,N′,N′-tetramethyl-1,6-hexanediamine, N,N′,N″-tris(dimethylaminopropyl)hexahydrotriazine, and 2,2′-dimorpholinyldiethyl ether, are described in US 2011/0154874 A1.

The storage life of the urease inhibitor is limited. The higher the temperature, the shorter the storage life. If, for example, urea is stored under tropical conditions, a major part of the urease inhibitor has undergone decomposition, generally, after about four weeks of storage. If the urease inhibitor is introduced into the urea melt, the decomposition is less. For the commercialization of the urea stabilized with the urease inhibitor, however, it is often vital to apply the urease inhibitor to urea and to store the treated fertilizer until the time of its spreading to the soil.

Moreover, the use of the compositions of the invention as additive or coating material for nitrogen-containing fertilizers has been found.

Preferred embodiments are explained in the claims and the specification. It is understood that combinations of preferred embodiments are within the scope of the present invention.

The term “at least one” is to be understood as 1, 2, 3 or more. A mixture comprising at least one amine refers for example to a mixture comprising 1, 2, 3 or more amines.

The term “soil” is to be understood as a natural body comprised of living (e.g. microorganisms (such as bacteria and fungi), animals and plants) and non-living matter (e.g. minerals and organic matter (e.g. organic compounds in varying degrees of decomposition), liquid, and gases) that occurs on the land surface, and is characterized by soil horizons that are distinguishable from the initial material as a result of various physical, chemical, biological, and anthropogenic processes. From an agricultural point of view, soils are predominantly regarded as the anchor and primary nutrient base for plants (plant habitat).

The term “fertilizer” is to be understood as chemical compounds applied to promote plant and fruit growth. Fertilizers are typically applied either through the soil (for uptake by plant roots) or by foliar feeding (for uptake through leaves). The term “fertilizer” can be subdivided into two major categories: a) organic fertilizers (composed of decayed plant/animal matter) and b) inorganic fertilizers (composed of chemicals and minerals). Organic fertilizers include manure, slurry, worm castings, peat, seaweed, sewage, and guano. Green manure crops are also regularly grown to add nutrients (especially nitrogen) to the soil. Manufactured organic fertilizers include compost, blood meal, bone meal and seaweed extracts. Further examples are enzymatically digested proteins, fish meal, and feather meal. The decomposing crop residue from prior years is another source of fertility. In addition, naturally occurring minerals such as mine rock phosphate, sulfate of potash and limestone are also considered inorganic fertilizers. Inorganic fertilizers are usually manufactured through chemical processes (such as the Haber-Bosch process), also using naturally occurring deposits, while chemically altering them (e.g. concentrated triple superphosphate). Naturally occurring inorganic fertilizers include Chilean sodium nitrate, mine rock phosphate, and limestone.

“Manure” is organic matter used as organic fertilizer in agriculture. Depending on its structure, manure can be divided into liquid manure, semi-liquid manure, stable or solid manure and straw manure. Depending on its origin, manure can be divided into manure derived from animals or plants. Common forms of animal manure include feces, urine, farm slurry (liquid manure) or farmyard manure (FYM) whereas FYM also contains a certain amount of plant material (typically straw), which may have been used as bedding for animals. Animals from which manure can be used comprise horses, cattle, pigs, sheep, chickens, turkeys, rabbits, and guano from seabirds and bats. The application rates of animal manure when used as fertilizer highly depends on the origin (type of animals). Plant manures may derive from any kind of plant whereas the plant may also be grown explicitly for the purpose of plowing them in (e.g. leguminous plants), thus improving the structure and fertility of the soil. Furthermore, plant matter used as manure may include the contents of the rumens of slaughtered ruminants, spent hops (left over from brewing beer) or seaweed.

The compositions of the invention are referred to as the compositions (Q1), (Q2), and (Q3) in the following. The composition (Q1) comprises (A) and (B)—latter in an amount of more than 10 wt. % based on the total weight of (Q1)—and optionally further components as described below. The composition (Q2) comprises (A) and (C) and optionally further components as described below. The composition (Q3) comprises (A) and (D) and optionally further components as described below.

Preferably, said process comprises: applying the compositions (Q1), (Q2), or (Q3) by spraying it onto the soil. More preferably, said process are conducted in a way wherein the compositions (Q1), (Q2), or (Q3) are—either at the same time (i.e. simultaneously) or with a time difference (i.e. separately)—applied together with at least one nitrogen-containing fertilizer (F) into the soil in-furrow and/or as side-dress and/or as broadcast.

According to the invention, the compositions (Q1), (Q2), or (Q3) can be used as additive or as coating material for nitrogen-containing fertilizers (F), particularly for urea-containing fertilizer (F1), for example for urea. According to one preferred embodiment, the compositions (Q1), (Q2), or (Q3) are used as coating material for nitrogen-containing fertilizers (F), particularly for urea-containing fertilizer (F1), for example for urea. The nitrogen-containing fertilizer (F) cam be in crystalline, granulated, compacted, prilled or ground form, and is preferably in granulated from.

The compositions (Q1), (Q2), or (Q3) can be applied to or on nitrogen-containing fertilizers (F) by either mixing the (Q1), (Q2), or (Q3), in either liquid or solid form, with the nitrogen-containing fertilizer (F), or incorporating them into (F) by granulation, compacting or prilling, by addition to a corresponding fertilizer mixture or to a mash or melt.

This can also be done using further auxiliaries such as adhesive promoters or encasing materials. Examples of apparatuses suitable for performing such application include plates, drums, mixers or fluidized-bed apparatus, although application may also take place on conveyor belts or their discharge points or by means of pneumatic conveyors for solids.

Application takes place preferably to an agriculturally or horticulturally exploited plot.

In parallel with the improvement of the utilization of nitrogen in the urea-containing, mineral and organic fertilizers, the use of the compositions (Q1), (Q2), or (Q3) has the effect that there is an Increase—in some cases considerably—in the yields or production of biomass of crop plants.

The compositions (Q1), (Q2), or (Q3) may be added to organic fertilizers, such as liquid manure, for example, during the actual storage of such fertilizers, in order thus to prevent nitrogen nutrient losses, by virtue of decelerated conversion of the individual forms of nitrogen into gaseous nitrogen compounds, which are therefore volatile, and in order as a result, at the same time, to contribute to a lowering of the ammonia load in animal stables.

In this context it is immaterial whether the compositions (Q1), (Q2), (Q3) are incorporated, by melting, for example, into the nitrogen-containing fertilizer (F), or else are applied to the fertilizer surface or applied separately from the spreading of the fertilizer, in the form, for example, of a (suspension) concentrate, a solution or a formulation.

The advantages of the invention are that the enhancement of the stability of the (thio)phosphoric acid triamide(s)—particularly when applied to or coated on nitrogen-containing fertilizers such as urea—and a relatively long storage life—particularly before being applied to or coated on nitrogen-containing fertilizers—was achieved with the compositions (Q1), (Q2), (Q3). Moreover, the compositions (Q1), (Q2), (Q3) do not adversely affect the urease-inhibiting effect and/or activity of the (thio)phosphoric acid triamide. Last, but not least, the compositions (Q1), (Q2), (Q3) can be easily and safely packaged, transported and shipped, even in large quantities, and can be easily and safely handled and applied for soil treatment, even in large quantities

The examples which follow illustrate the invention without restricting it.

Preparation of the Formulations

Preparation of the Formulation

According to the ratios and components as specified in Table 2, all components were mixed, and the resulting mixture was stirred until complete dissolution of the solid and analyzed for the content of NBPT, NPPT, NxPT (by HPLC), viscosity, dissolution (2%) in water and pH.

For example, in case of Ex. #310092, the technical mixture LT (25% pure NxPT) was mixed with 50.08% benzyl alcohol and 10% LFG, 10% DML and 0.25% colo. The mixture was stirred until complete dissolution of the solid and analyzed for NxPT content (by HPLC), viscosity, dissolution (2%) in water and pH.

Formulation Storage Stability

The mixture of each example (e.g. Ex.#310092) was stored in closed bottles for 14 days at 54° C. (referred to as heat stability test in the following) and then analyzed for the content of NxPT. The mixture of each example (e.g. Ex.#310092) was also stored in closed bottles for 14 days at 5° C. (referred to as cold stability test in the following) and then analyzed for the content of NxPT. The storage stability in % was calculated as difference between the content in the heat stability test and the content in the cold stability test.

Coating of Urea

EXAMPLE 1.1

500 g granulated urea was charged to a rotating drum (Type Hege 11) and 2 g of the formulation of each example (e.g. Ex.#310092) was sprayed on the urea using a rotating disc. The homogeneous coated urea was discharged after 1 min and analyzed for the content of NBPT, NPPT, NxPT (by HPLC).

Stability on Urea

The coated urea sample of 300 g was stored in a petri dish for 4 weeks at 50% humidity in a climate chamber. For analysis the sample was homogenized and analyzed for the content of NBPT, NPPT, NxPT (by HPLC)

The content of NxPT measured by HPLC measurement is always the sum of the both components NBPT and NBPT.

Viscosity was measured at the undiluted formulation with a cone-plate rheometer AR 2000ex (TA Instruments) at shear rate of 100 s−1 and 20° C.

The pH value was measured at 2% concentration in CIPAC water D.

All examples of the inventions are liquid, clear compositions which are either colourless or yellow.
