DESC:Technical Field
The present disclosure relates to agricultural bio nanotechnology. More particularly, the present disclosure relates to nutritional ionic liquid based chelated plant nutrient composition and method for preparing chelated plant nutrient composition.
Background
Several fertilizers and plant nutrients are applied to plant and soil through foliar or irrigation. For many years, agricultural experts have observed that greater yields have been achieved when applying fertilizer via foliar spray directly to plant leaves.
It has been found that a very low level of iron, copper, manganese, cobalt, magnesium, calcium, and zinc is beneficial, if not essential, for plant and animal life. Due to plant absorption, as well as other reasons including erosion, insolubility from interaction with other materials in the soil, and/or weathering, the soil or other growing medium may become depleted of certain elements during agriculture. This means that these micronutrients must be replenished in order for the growing medium to be utilized again for fresh crops. Numerous issues including stunted growth and crop loss could arise from a deficiency or depletion of certain micronutrients. Moreover, livestock animals that eat low-micronutrient grasses and other vegetation don’t get all the micronutrients they need, which can lead to poor health and/or sluggish growth. Several chelating ligands including four, six and eight coordination sites are developed for making unavailable metal salts/ores of micronutrients to convert and maintain bioavailability through the formation of coordination complexes.
The most popular chelating agent like ethylene diamine tetra acetic acid (EDTA) can be able to form a cage-like clustered metal complex structure through six coordination sites by using two amines and four carboxylic acid functional groups; that can resist any reactivity with oxide or hydroxide ions present in the metal ion’s environment. Consequently, the metal ion can retain its bioavailable state even in the presence of reactive caustic anions until it can contact a root hair and be taken up by the plant.
Generally, metal sulphates have been directly added in bulk quantities to the soil to restore micronutrients. This approach had some shortcomings. First, most of the metal sulphate either would run off in the initial water application, leach into lower depths of the soil, or the metal would oxidize and have limited bioavailability. Second, the metal ions would react with soils (acidic or alkaline or neutral soil) to form insoluble metal salts, which are mostly in the form of non-bioavailable oxides and hydroxides. Overuse of chemical fertilizers is causing the soil’s fertility to decline, the health of the soil to deteriorate and ultimately environmental pollution will be increasing. Generally, chemical fertilizers, herbicides, weedicides, and other agrochemicals are having negative consequences on people’s health. This leads to increasing diseases like cancer in recent years.
Ionic liquids (ILs) emerged as a greener alternative to conventional organic solvents thanks to their low volatility and flammability and their wide liquid-state window. These solvents have demonstrated special features that have found a broad application in analytical, catalysis, nanotechnology, lubricants, energy storage devices, gas separation technologies, speciality chemicals including surface reducers and agrochemicals. ILs are tuneable and can be adapted to extract a given analyte by the proper selection of their constituent ions. Currently, it’s “official” definition uses the boiling point of water as a point of reference: “These are ionic compounds which are liquids below 100 °C.” More commonly, these have melting points below room temperature; some of them even have melting points below 0 °C. These new materials are liquid over a wide temperature range (300–400 °C) from the melting point to the decomposition temperature of these compounds.
The latest studies indicate a significant increase in interest in greener or eco-friendly compounds in agrotechnical treatments. Therefore, ionic liquids technology-based compounds are focused by various industrial sectors in their own aspects. However, this is very new technology for agrochemical industrials. So far very few ionic liquid-based compounds were developed for agrochemical applications such as used as herbicide, surfactant, antibacterial, antifungal and growth promotors.
Phosphorous is an essential for the strength of plants and their blossoms. Additionally, vital to promote flowering and avoid flower shedding. Mostly, super phosphate, diammonium phosphate (DAP), urea ammonium phosphate, monoammonium phosphate, ammonium polyphosphate, and similar substances are examples of inorganic water soluble phosphorus sources for plants. However, they are infrequently available to plants. According to research, almost 75-95% of phosphorus fertilizers are fixed in the soil. The solution utilizing this cutting-edge technology helps to address the persistent issue of low phosphorus supply and offers better phosphorus efficiency, more production potential, and higher profitability.
Potassium is another essential nutrient for the growth of sugar and carbohydrates in plants. This could help crops in a way to defend against their diseases. It has the potential to thicken plant cells, reinforce stalks and stems, and lessen the likelihood that some illnesses may infect the plant after heavy rain or other stressful circumstances. And it also plays a vital role in photosynthesis.
Furthermore, when applied as foliar fertiliser, inorganic sources of nitrogen, phosphorus, and potassium are not entirely absorbed by plants since they cannot penetrate the leaf surface due to their inorganic character and must instead form complexes with certain organic molecules (Organic molecules acting as a transporter and are produced during the photosynthesis using C, H, O). Transport and absorption of nutrients are significantly impacted if the plant does not make enough of these organic compounds. However, the availability of nutrient fertiliser is significantly increased if it is made available as an organic complex. To address the following various difficulties, a solution must be offered. N-P-K, nutrients, and agrochemicals should be provided in a form that is highly assimilable to enable maximal usage.
Boron (B) is one of the essential micronutrients required for normal plant growth and development. Particularly, it plays a vital role in cell wall binding with pectic polysaccharides. Mostly boron fertilizers are used as water-soluble salts such as boric acid, sodium tetraborate, borax and octoborate. The drawback of the above is the efficient usage of boron is very low due to losses of leaching after application and before up taken by the plant and also there is a risk of toxicity to seedlings after planting. Recently, the deficiency of boron is frequently mentioned as one of the important issues worldwide. Furthermore, crop production is another notable feature of limiting boron effects that can be found in various fields, including horticultural and woody crops. Recent literature has shown that the impact of B deficiency can lead to reduce yields or damage the quality of the crop yield.
The dearth of information on iron and manganese oxyethylidene diphosphonates in the patent literature during the past 20 years was shown by a patent search using the FPQ service (US Patents, US Patents Applications, EP papers, Abstracts of Japan, German Patents). Three works were found after using the Sci Finder universal search engine to look up the same name in the American Chemical Society database. In the patent, copper salt with HEDP is used for the pre-sowing dressing of grain crops; magazines mention the issues with steel corrosion and scale formation in steel boilers. These publications are strictly scientific and do not include information on the preparative isolation of the by-products of the equilibrium reactions of HEDP with water-soluble iron salts or on the resistance to precipitation of concentrated solutions of these compounds. As a result, just three studies on iron and manganese compounds with HEDP can be found in periodicals, and there is no information on them in the patent literature. The method of synthesis is not described. It is only known that the iron complex, which is made from iron chloride and the sodium salt of HEDP is poorly soluble in water. The same article describes how manganese (II) acetate interacts with an aqueous solution of the HEDP disodium salt to produce manganese oxyethylidene diphosphonate monohydrate.
Iron (III) and manganese (II) oxyethylidene diphosphonates are very poorly soluble in water. Some of them, which are readily soluble when first created, rapidly lose their solubility nature over the period of time and even when kept in the form of solid powders. A modest increase in solubility is caused by the higher concentration of HEDP fragments in the coordination compound, but it is insufficient to produce concentrated solutions. A technique for improving the solubility of metal oxyethylidene diphosphonates was put forth that involved carefully treating aqueous solutions with caustic alkalis under controlled circumstances. The suggested method has a significant drawback: reactions with alkalis must be conducted slowly and under carefully monitored circumstances, as fast mixing results in the precipitation of insoluble metal hydroxides.
These chelated nutrient combinations can be sprayed onto plants, or it can be disseminated onto the soil or injected directly into the roots. And the mixture is preferably sprayed onto a granular carrier or mixed with other material that can be used in agriculture as a granular substance.
The results of the literature and patent searches were as follows. There is a severe lack of knowledge about zinc, copper, molybdenum, cobalt, nickel, titanium, selenium, manganese, and iron compounds. Three studies that are available online describe the creation of chemicals that are only moderately soluble in water, such as zinc and iron oxyethylidene diphosphonates. Their solubility can be made more soluble by treating them with an alkali. However, the solubility and bioavailability of metal has been reduced in time being process. This is the reason, this type of material is not successful in agrochemical application, so far in commercial aspects. And this issue was rectified through the ionic liquid technology.
Currently, micronutrients deficiency is the most important issues in the world which causes huge losses in crop production both quantitatively and qualitatively. Generally, deficiency of micronutrients leads to effects on the vegetative and reproductive growth of plants resulting in reduced cell expansion and fertility. There are numerous adverse effects on crop yield obtained due to micronutrients deficiency can be varied through the different organs, from roots, stem, petiole, leaf, peduncle, flower, seed and fruit. Particularly, the symptoms of deficiency of micronutrients lead to apical growth inhibition, leaf expansion reduction, terminal bud necrosis, flower abortion and fruit shedding. Among them, one of the initial responses to micronutrients deficiency for plants is the inhibition of cessation of root elongation. Plants have both water-soluble and insoluble forms of micronutrients. The quantity of water-soluble micronutrients varies with the quantity of micronutrients supplied whereas insoluble micronutrients does not. The decrease of water-insoluble micronutrients leads appears and coincides with deficiency symptoms of micronutrients which clearly shows the insoluble micronutrients present in the form of functional while the soluble micronutrients represent the surplus.
For example, boron is considered a beneficial micronutrient for animals and humans both because it prevents losses of Ca and Mg from their bodies. As enshrined in the essentiality criteria, every micronutrient performs a specific role in plant, animal and human metabolism and its deficiency/role cannot be mitigated/substituted by any other element. Minerals applied to crops for their nourishment improve their concentration/content in the plant tissues. Inadequate supply of these nutrients in micronutrient deficient soils can lead to loss of yield as well as the quality of product, and consequentially health of animals and humans feeding thereon per se and also their productivity.
In recent days chelating agents have been focused more due to their less environmental toxicity and it makes micronutrients available to plants for a long time. EDTA (ethylene diamine tetraacetic acid) is one of the important chelating agents which has been used in many countries for more than one decay. Due to the high usage of EDTA, European groundwater was contaminated with these organic compounds, and it has the potential to disturb the natural species of metals and to influence metal bioavailability. Therefore, this high concentration of a chelating agent may lead to involving the remobilization of metals from sediments and aquifers, consequently posing a risk to groundwater and drinking water.
Generally, many chelating agents such as Ethylenedinitrilo-tetraacetic acid (EDTA), 2-[Bis(carboxymethyl)amino] acetic acid (NTA), 2-hydroxypropane-1,2,3-tricarboxylic acid, amino acid, and phosphonates are slowly biodegradable and are therefore rather persistent in the environment. Natural waters contain strong chelating agents predominantly in the form of metal complexes. The importance of chelation on metal bioavailability was established by several studies. Conversely, the type of metal presence also affects the chelating agents due to the various reactivity of metal chelates. Recently, much of the research emphasized phosphonate-bearing chelators due to their known hard ionic co-ordinations electronics as well as their instant kinetics of complexation. Particularly, phosphonates are well suited towards the complex formation through the coordination of hard metal ions, including a small high valent main group (gallium, aluminium) and transition metals as well as the entire lanthanides series. In addition, bisphosphonates have interesting features as they can easily interact with bone.
Therefore, there is a need to overcome the limitations associated with traditional chelating agent, toxicity associated with the chelating agent to ground water and drinking water.
