Definitions
- the present invention relates to an effect-enhanced nutrient composition for the timed release of trace elements in rhizodermal and epidermal regions of plants. Moreover, the present invention relates to the use of such a nutrient composition in a method for fertilizing plants, with which a time-controlled release of trace elements in the rhizodermal and epidermal region of plants takes place.
- plants In order to ensure healthy growth, plants have to extract various nutrients from the soil in which they grow. However, many soils are deficient in certain elements, or they are present in a form unavailable to plants.
- Enhanced Efficiency Fertilizers have certain formulations, contain specific additives, or have particular physical properties that have the potential to increase plant nutrient uptake, ideally to deliver a linear to sigmoidal nutrient delivery, with the goal of increasing nutrient delivery Need to synchronize in the course of plant growth and to protect the nutrients from reactions in the soil, or in the leaf application on the plant surface, which can reduce the availability of plants.
- the supply of fertilizers can be done via the soil or by application to the above-ground parts of plants.
- nutrients such as trace elements, can be provided in the rhizodermal or epidermal region of plants.
- rhizodermal refers here to the terminus tissue of the plant root, the rhizodermis.
- epidermal in contrast, refers to the terminus tissue of the above-ground parts of plants, the epidermis.
- the release of the nutrients it contains is essentially controlled by the water solubility of the formulation surrounding it.
- the fertilizer particles are in a particular carrier matrix, such as e.g. a mixture of melted waxes, surfactants and polyethylene glycols embedded.
- this approach requires a large amount (up to 40%) of carrier material.
- the release of the nutrients is highly dependent on the quality of the coating.
- granules may directly release up to a third or more of the nutrients when in contact with water, and on the other hand, in part, one third of the nutrients are released only long after they are needed by the plant. These patterns of release vary significantly from the desired linear to sigmoidal form of nutrient delivery.
- Another disadvantageous aspect of polymer-coated fertilizers is that their use can result in undesirable accumulation of plastic debris in the treated floors.
- US Pat. No. 3,574,591 describes slow-dissolving ammonium-potassium-metal polyphosphates having a straight or branched chain structure.
- US 2010/0024026 virtually insoluble trace element fertilizers in the form of polymerized metal phosphates are described in water, which can go into solution in an acidified environment.
- the object of the present invention was to provide a prior art improved nutrient composition which timely releases the nutrients therein when the nutrient composition is provided in the rhizodermal and epidermal region of the plants. 4. Solution of the object of the invention
- At least one mixed metal crystalline orthophosphate type [T a (M1 M2 M3 ... Mx) b (P04) c ⁇ n H 2 0] contains wherein T is selected from NH 4, K or CH 4 N 2 O; and M1, M2, M3 ... Mx are metals selected from Mg, Ca, Mn, Fe, Co, Ni, Cu and Zn, the mixed metallic orthophosphate containing at least two different metals with the proviso that at least one of said at least two different metals M1, M2, M3 ...
- Mx is selected from Mn, Mg and Ca, the total amount of Mn, Mg and / or Ca being in the sum in the range from 0.5 to 90 mol% based on the total amount of all metals contained in the mixed metallic orthophosphate.
- One strategy of plants is to reduce rhizodermal pH by the mechanism of the 'proton pump' or by the targeted delivery of organic acids (e.g., malic and citric acids) through the plant root.
- organic acids e.g., malic and citric acids
- the pH in the rhizosphere root zone can decrease by up to 2 pH gradients, and the acidification significantly increases the solubility and hence availability of metal ions, thus improving nutrient uptake.
- a second possibility of nutrient uptake, especially of trace elements, is the absorption of ionic elements via the epidermal leaf surface into the plant parenchyma. At the leaf surface, nutrient crystals can slowly go into solution at low pH and thus be converted into an absorbable form.
- the pH change in the acidic region is exemplified by CO2, which when dissolved in water (film) on the Leaf surface carbonic acid forms (H2CO3), and also by acidic substances on the leaf surface (from the deposition of substances from the atmosphere), such as ammonium sulfate, ammonium hydrogen sulfate or "acid rain.”
- CO2 When dissolved in water (film) on the Leaf surface carbonic acid forms (H2CO3), and also by acidic substances on the leaf surface (from the deposition of substances from the atmosphere), such as ammonium sulfate, ammonium hydrogen sulfate or "acid rain.”
- the plants treated with the present nutritional compositions can specifically mobilize nutrients from the nutrient composition. Not only does this improve availability over time, it also reduces the uncontrolled release of nutrients to the environment, with optimal adjustment of the ratio of water and acid solubilities. It thus provides effective fertilizers with depot function, which ensure a timely controlled nutrient release in the rhizosphere of the treated plants, without causing excessive nutrient input into the environment.
- organic acids e.g., citric acid
- the crystalline mixed metal orthophosphates of the present invention are salts of phosphoric acid which, unlike polyphosphates, are in uncondensed form.
- the crystalline mixed-metal orthophosphates of the present invention are characterized by a regular and continuous arrangement of the orthophosphate molecules and possibly existing crystal water in a crystal structure which can be detected by the reflections occurring in an X-ray diffraction analysis (see FIG. 8).
- the experiments of the inventors described in detail below have shown that the presence of Mn, Mg and / or Ca in the crystal structure allows the water and acid solubility of the mixed metallic orthophosphates to be adjusted individually.
- a further advantage resulting from the crystal structure of the mixed-metal crystalline orthophosphates according to the invention is that the metals enclosed in the crystal lattice are protected from oxidative influences.
- the integrated trace elements in the mixed metallic crystalline orthophosphates of the present invention are preferably in the preferred bivalent absorption form of the plant (Fe 2+ , Mn 2+ , Cu 2+ , Zn 2 + or Mg 2+ ). Especially in these cases, therefore, the protection against oxidative influences by including the metals in a crystal lattice of particular advantage. 6.
- the advantages of the present invention are achieved by the claimed mixed-metal crystalline orthophosphates in which the total amount of Mn, Mg and / or Ca in the sum in the range of 0.5 to 90 mol% relative to the total amount of all in the ge mixed metallic orthophosphate metals contained.

- the upper limit of the total content of Mn, Mg and / or Ca in these embodiments is optionally up to 90 mol%, 85 mol%, up to 80 mol%, up to 75 mol% or up to 70 mol% ,
- the molar ratio of Mg or Ca or the sum of Mg and Ca on the one hand to Mn on the other hand is in the range of 0.5: 1 to 10: 1.
- the molar ratio of Mg or Ca or the sum of Mg and Ca on the one side to Mn on the other side is at least 1: 1, at least 2: 1 or at least 5: 1 and up to 10: 1 each.
