Description
I
Use of aminocarboxylates in agriculture The present invention relates to the use of formulations comprising (A) one or more aminocarboxylates, selected from among methylglycine diacetate (MGDA) and its alkali metal salts and glutamic diacetate (GLDA) and its alkali metal salts, (B) at least one inorganic compound selected from among inorganic phosphates, inorganic phosphites, inorganic nitrates, ammonium salts and potassium salts and (C) optionally water for the application to plants, the ground or growth substrates.
In some embodiments, the invention relates to the use of a formulation comprising (A) one or more aminocarboxylates selected from the group consisting of methylglycine diacetate (MGDA) and its alkali metal salts and glutamic diacetate (GLDA) and its alkali metal salts, (B) at least one inorganic compound selected from the group consisting of inorganic phosphates, inorganic phosphites, inorganic nitrates, ammonium salts and potassium salts, and (C) optionally water, wherein the formulation has a pH value in the range from 6 to 8, for the application to plants, the ground or growth substrates.
In some embodiments, the invention relates to a method of fertilizing plants, wherein at least one formulation comprising (A) one or more aminocarboxylates selected from the group consisting of methylglycine diacetate (MGDA) and its alkali metal salts and glutamic diacetate (GLDA) and its alkali metal salts, (B) at least one inorganic compound selected from the group consisting of inorganic phosphates, inorganic phosphites, inorganic nitrates, ammonium salts and potassium salts, and (C) optionally water, the formulation having a pH value in the range from 6 to 8, is applied mechanically or manually to the ground and/or to plants.
The present invention furthermore relates to formulations comprising (A) one or more aminocarboxylates, selected from among methylglycine diacetate (MGDA) and its alkali metal salts and glutamic diacetate (GLDA) and its alkali metal salts, (B) at least one inorganic compound selected from among inorganic phosphates, inorganic phosphites, inorganic nitrates, ammonium salts and potassium salts and (C) optionally water.

la The present invention furthermore relates to a process for the preparation of formulations according to the invention. The present invention furthermore relates to the use of aqueous formulations comprising (A) one or more aminocarboxylates, selected from among methylglycine diacetate (MGDA) and its alkali metal salts and glutamic diacetate (GLDA) and its alkali metal salts, to be applied to plants or the ground or growth substrates.
It has long been attempted to improve the yields of soils in terms of fertility. By using fertilizers, in particular what are known as NPK fertilizers, it is indeed possible to improve the essential mineral content. However, it is observed that, in many cases, only fractions of the minerals supplied to the soil are indeed taken up into plants. A considerable fraction of the minerals supplied, in contrast, is not taken up but enters the groundwater, where in particular nitrates and phosphates are undesired. Excess fertilizer application, therefore, is not acceptable.
Regular fertilizing with low fertilizer concentrations is too time-consuming.
The bioavailability of phosphates is a problem. Phosphate minerals which, in many cases, include phosphate in a sparingly water-soluble form will in many cases not be effective as phosphate fertilizer in nature. The use of what are known as soluble phosphates, which has already been proposed as a solution, will, in soils which comprise significant amounts of calcium or iron ions in dissolved form, result in the precipitation of sparingly-soluble phosphates, so that the problem of the bioavailability of phosphate cannot be considered as solved.

What is know
2 as the mineralization of soluble phosphates can take place within a period of less than two weeks, depending on the soil composition.
An object was therefore to provide formulations whose mineral fertilizer component can be taken up readily by soils or plants. A further object was to provide uses of formulations by means of which mineral fertilizers, and in particular phosphate, can be taken up readily by soils or plants. A further object was to provide a method by means of which phosphate can be rendered readily bioavailable.
Accordingly, there have been found the uses and formulations defined at the outset.
According to the invention, there is used at least one formulation comprising (A) one or more aminocarboxylates, selected from among methylglycine diacetate (MGDA) and its alkali metal salts and glutamic diacetate (GLDA) and its alkali metal salts, in each case also called aminocarboxylate (A) or else, summarily, compound (A) for short, (B) at least one inorganic compound, also called inorganic compound (B) for short, selected from among inorganic phosphates, inorganic phosphites, inorganic nitrates, ammonium salts and potassium salts and (C) optionally water for the application to plants or the ground or growth substrate.
Compound (A) can be present as the free acid or, preferably, in partially or fully neutralized form, in other words as a salt. Examples of suitable counterions are inorganic cations, for example ammonium, alkali metal or alkaline-earth metal, preferably Mg2+, Ca2+, Nat, K+, or .. organic cations, preferably ammonium which is substituted by one or more organic radicals, in particular triethanolammonium, N,N-diethanolammonium, N-mono-Ci-C4-alkyldiethanolammonium, for example N-methyldiethanolammonium or N-n-butyldiethanolammonium, and N,N-di-C1-C4-alkylethanolammonium. Preferred ions are alkali-metal ions, especially preferably Nat and K.
In one embodiment of the present invention, compound (A) is selected from among derivatives of aminocarboxylates (A), for example from their methyl or ethyl esters.
Compound (A) is selected from among methylglycine diacetate (MGDA) and glutamic diacetate (GLDA) and their derivatives and preferably their salts, in particular their sodium and potassium salts. Very especially preferred are methylglycine diacetate and the trisodium salt of MGDA.
