Definitions

  • the present invention related to a novel water soluble fertilizer composition and method of preparation thereof. More preferably, the present invention provides a novel cationic liquid, Sodium and Chloride free, water-soluble nano-formulation fertilizer composition comprising primary nutrients Nitrogen, phosphorous and Potassium and preparation method thereof.
  • the novel fertilizer comprises of sufficient amount of source of primary nutrients Nitrogen, phosphorous and Potassium in soluble form and additional excipients.
  • the additional excipients includes chelated metals, humectants, emulsifiers, preservative.
  • the fertilizer of the present invention is cationic in nature, free of acid or alkali factors such as chloride or sodium and is having neutral pH as better foliar application solution for crop management.
  • the fertilizer composition of the present invention can well regulate the growth of crops and increase the yield of the crops. BACKGROUND AND PRIOR ART OF THE INVENTION: Nitrogen (N), potassium (K), and phosphorus (P) are nutrients, that are utilized by the plants for their important physiological growth like root development, early and active vegetative growth and inflorescence & fruit leading to increased nutritive value and yield of the produce.
  • Nitrogen is an important component of chlorophyll (with this compound, plants use sunlight energy to produce sugar from water and carbon dioxide ( during the process of photosynthesis)). It is also the main component of amino acid (the building block of protein). Without protein, plants wither and die. Some proteins act as the building blocks of plant cells, while others act as enzymes, which are essential for many biochemical reactions. Nitrogen is a component in energy transfer compounds such as ATP (adenosine triphosphate). ATP allows cells to preserve and use the energy released by metabolism. Additionally, nitrogen is an important component of nucleic acid (such as DNA) of genetic material that enables cells (ultimately tissues and all plants) to grow and reproduce.
  • ATP adenosine triphosphate
  • Phosphorus Phosphorus is an important component in plant DNA and RNA. Phosphorus is also important for the development of roots, flowers, seeds, and fruits, the energy required by plants, and the intake of other elements (including N).
  • Potassium (K) Potassium is important for strengthening stem growth, water flow, and intake of other elements in plants. Potassium also plays a key physiological role in the metabolism of carbohydrates and protein in plants, promoting flowering and fruiting. Because of the unavailability or exhaustion of primary metal ions and additional micronutrients is very often observed in the soil, hence the cause of poor plant growth and finally poor crop yield.
  • NPK grade straight bulk fertilizer in the soil are subjected to non-availability due to its intrinsic property of mobility in soil often don’t reach the root zone and remain fixed in the soil or may leach down beyond root zone making non available to plants. Therefore, to correct the deficiency of available nutrients and to make it quickly available through liquid formulation having nano particles so that absorption during foliar application to crops are quick and on right time of physiological growth of the crops .
  • NPK Nitrogen-Phosphorous-Potassium
  • the relevant N-P-K based fertilizer can be utilised to manage the soil nutrients and specific plant requirement to fight with nutrient deficiencies and disorders to provide better yield from the crop.
  • the conventional available NPK fertilizer has some limitations: Firstly, the conventional water soluble NPK fertilizers like NPK 4-11-11 comprising ammonium polyphosphate and potassium chloride are prepared from salts of sodium and chloride. These alkali ions show adverse effect on absorption of essential nutrients in the plant. Sodium and chloride ions separate when salts are dissolved in water. The dissolved sodium and chloride ions, in high concentrations, can displace other mineral nutrients in the soil.
  • the patent document US 5,997,600 discloses fertilizer additives comprising micronutrients in the form of chelated metal ions with citric acid.
  • Micronutrients are selected from calcium, magnesium, manganese, iron, cobalt, copper, Zinc, molybdenum, which can be added to conventional NPK compositions.
  • the said fertilizer additives include a sufficient quantity of amine to maintain the pH above about 7.5 and preferably about 8-11.
  • the problem of conventional NPK fertilizer is remain same as disclosed above even if someone wants to use this additive to provide micronutrients.
  • the conventional NPK fertilizer with different concentration of NPK are available in market, but they are in powder form (water insoluble or water soluble powder).
  • the patent application WO 2014/041556 Al discloses such powder form of NPK fertilizer comprising chelated fertilizer composition for enriching Zinc and Phosphorus content in agriculture/horticulture crops and plants through foliar application.

  • the chelation of Zn by Na2 HEDP using ZnS0 4 .H 2 O developed 17% Zn-HEDP and 21% Phosphorus pentoxide (P 2 0 5 ) and chelation of Zn by Na 2 HEDP using ZnO developed 21% Zn-HEDP and 26% P205.
  • the chelated fertilizer composition obtained is in powder form and is 100% water-soluble concentrate.
  • the said fertilizer is consisting of sodium and also acidic composition having pH between 3.5 to 4.5..
  • the most of the fertilizer compositions contain Sodium (Na) and Chlorine (Cl) that are responsible to alter the final pH of the final composition.
  • foliar fertilizer is a fertilizer product which is designed to be applied directly to the leaves of a plant. Now the important part is that, since soils are negatively charged and plant nutrients are positive and negative.
  • the present invention is developed in order to give better and effective fertilizer composition comprising sufficient primary nutrients as well as micronutrients for crop management with cationic liquid, water-soluble fertilizer composition without undesirable alkali content such as Sodium (Na) and Chlorine (Cl) at neutral pH for maximum plant availability of Nitrogen, Phosphorous and Potassium source.
  • the present invention fertilizer is comprising of humectant, preservative and emulsifier combination that prevents undersaturation of liquid composition at lower atmospheric temperature (below 2 oC) or higher atmospheric temperature (above 35 oC).
  • the present invention provides a novel cationic liquid, Sodium and Chloride free, 100% water-soluble fertilizer in liquid form composition comprising different concentrations of primary nutrients selected from Nitrogen, phosphorous and Potassium, using preparation of water soluble cationic agents from the primary nutrients sources along with other essential micronutrients like Zinc (Zn), Iron (Fe), Copper (Cu), Manganese (Mn), Calcium (Ca), Magnesium (Mg).
  • micronutrients are in the form of chelated complex with Ethylenediaminetetraacetic acid (EDTA) and salts of Molybdenum (Mo) and Boron (B) without any risk of scorching/phytotoxicity and to give better yield with appropriate application rate.

Description

TITLE OF THE INVENTION: SODIUM AND CHLORIDE FREE, WATER SOLUBLE FERTILIZER COMPOSITION HAVING PRIMARY NUTRIENTS NITROGEN- PHOSPHOROUS-POTASSIUM AND PREPARATION PROCESS THEREOF FIELD OF INVENTION: The present invention related to a novel water soluble fertilizer composition and method of preparation thereof. More preferably, the present invention provides a novel cationic liquid, Sodium and Chloride free, water-soluble nano-formulation fertilizer composition comprising primary nutrients Nitrogen, phosphorous and Potassium and preparation method thereof. The novel fertilizer comprises of sufficient amount of source of primary nutrients Nitrogen, phosphorous and Potassium in soluble form and additional excipients. The additional excipients includes chelated metals, humectants, emulsifiers, preservative. Wherein, the fertilizer of the present invention is cationic in nature, free of acid or alkali factors such as chloride or sodium and is having neutral pH as better foliar application solution for crop management. The fertilizer composition of the present invention can well regulate the growth of crops and increase the yield of the crops. BACKGROUND AND PRIOR ART OF THE INVENTION: Nitrogen (N), potassium (K), and phosphorus (P) are nutrients, that are utilized by the plants for their important physiological growth like root development, early and active vegetative growth and inflorescence & fruit leading to increased nutritive value and yield of the produce. The fundamental effect of NPK element in the NPK fertilizer is: Nitrogen (N): Nitrogen is an important component of chlorophyll (with this compound, plants use sunlight energy to produce sugar from water and carbon dioxide ( during the process of photosynthesis)). It is also the main component of amino acid (the building block of protein). Without protein, plants wither and die. Some proteins act as the building blocks of plant cells, while others act as enzymes, which are essential for many biochemical reactions. Nitrogen is a component in energy transfer compounds such as ATP (adenosine triphosphate). ATP allows cells to preserve and use the energy released by metabolism. Additionally, nitrogen is an important component of nucleic acid (such as DNA) of genetic material that enables cells (ultimately tissues and all plants) to grow and reproduce. In short, nitrogen promotes healthy plant growth. Phosphorus (P): Phosphorus is an important component in plant DNA and RNA. Phosphorus is also important for the development of roots, flowers, seeds, and fruits, the energy required by plants, and the intake of other elements (including N). Potassium (K): Potassium is important for strengthening stem growth, water flow, and intake of other elements in plants. Potassium also plays a key physiological role in the metabolism of carbohydrates and protein in plants, promoting flowering and fruiting. Because of the unavailability or exhaustion of primary metal ions and additional micronutrients is very often observed in the soil, hence the cause of poor plant growth and finally poor crop yield. Also application of NPK grade straight bulk fertilizer in the soil are subjected to non-availability due to its intrinsic property of mobility in soil often don’t reach the root zone and remain fixed in the soil or may leach down beyond root zone making non available to plants. Therefore, to correct the deficiency of available nutrients and to make it quickly available through liquid formulation having nano particles so that absorption during foliar application to crops are quick and on right time of physiological growth of the crops . Hence the different compositions of Nitrogen-Phosphorous-Potassium (NPK) are recommended for the production of different crops and at different stages of plant life cycle, which in turn improves the nutritional quality and levels of minerals, Phyto-nutrients and vitamins in said crop. Routine soil testing or visual observations of crops may confirms the nature of nutrient deficiency. Accordingly, the relevant N-P-K based fertilizer can be utilised to manage the soil nutrients and specific plant requirement to fight with nutrient deficiencies and disorders to provide better yield from the crop. The conventional available NPK fertilizer has some limitations: Firstly, the conventional water soluble NPK fertilizers like NPK 4-11-11 comprising ammonium polyphosphate and potassium chloride are prepared from salts of sodium and chloride. These alkali ions show adverse effect on absorption of essential nutrients in the plant. Sodium and chloride ions separate when salts are dissolved in water. The dissolved sodium and chloride ions, in high concentrations, can displace other mineral nutrients in the soil. Plants then absorb the chlorine and sodium instead of needed plant nutrients, leading to deficiencies. Secondly, the conventional water soluble NPK fertilizers like NPK 11-37-0 (ammonium polyphosphate) and 32-0-0 (ammonium nitrate, urea), can not be formulated into more than 50% concentration of all nutrients. Because, undersaturation condition. One more problem with conventional water soluble NPK fertilizers is related to undersaturation condition of liquid fertilizer at lower atmospheric temperature (below 2 ºC) or higher atmospheric temperature (above 35 ºC). Therefore, the stability of conventional liquid fertilizer are failing in lower/ temperature terrestrial countries such as in European countries and African countries. The patent document US 5,997,600 discloses fertilizer additives comprising micronutrients in the form of chelated metal ions with citric acid. Micronutrients are selected from calcium, magnesium, manganese, iron, cobalt, copper, Zinc, molybdenum, which can be added to conventional NPK compositions. The said fertilizer additives include a sufficient quantity of amine to maintain the pH above about 7.5 and preferably about 8-11. The problem of conventional NPK fertilizer is remain same as disclosed above even if someone wants to use this additive to provide micronutrients. The conventional NPK fertilizer with different concentration of NPK are available in market, but they are in powder form (water insoluble or water soluble powder). Foliar application of water insoluble powder is not recommended as quantity require per hectare is very high, high degree foliar deposition leads to scorching by toxic salts, MRL issues in produce and with drip application high deposition of insoluble inorganic compound destroy the soil quality over a period of time. The patent application WO 2014/041556 Al discloses such powder form of NPK fertilizer comprising chelated fertilizer composition for enriching Zinc and Phosphorus content in agriculture/horticulture crops and plants through foliar application. The chelated fertilizer composition compounds comprising (a) Na2 HEDP and ZnS04.H2O (Zinc sulphate monohydrate) and (b) Na2 HEDP and ZnO (Zinc Oxide). The chelation of Zn by Na2 HEDP using ZnS04.H2O developed 17% Zn-HEDP and 21% Phosphorus pentoxide (P205) and chelation of Zn by Na2 HEDP using ZnO developed 21% Zn-HEDP and 26% P205. The chelated fertilizer composition obtained is in powder form and is 100% water-soluble concentrate. The said fertilizer is consisting of sodium and also acidic composition having pH between 3.5 to 4.5.. The most of the fertilizer compositions contain Sodium (Na) and Chlorine (Cl) that are responsible to alter the final pH of the final composition. Appropriate pH of fertilizer composition as well as soil pH is responsible for good absorption of plant nutrients, and it has been derived that optimum pH range for plant growth is close to neutral e.g. between 6.5 to 7.5. Based on previous studies, there is strong evidence for the direct or indirect impact of ionic charge of fertilizer on absorption of plant nutrients. These experimental results provide a scientific basis toward the importance of having cationic fertilizer for foliar applications. The foliar fertilizer is a fertilizer product which is designed to be applied directly to the leaves of a plant. Now the important part is that, since soils are negatively charged and plant nutrients are positive and negative. Those nutrients that exist as anions (-) are moved through soil and hence meaning growers need to be careful to select formula as well as how they are applied regardless of soil type. Anions (-) solution based nutrients readily travel wherever water carries them, leading to nutrient runoff and leaching and economic loss and environmental concern. Therefore, the fertilizer with cations (+) charge are more efficient as they does not leach out and remain in plant for availability. Therefore, the inventor of the present invention developed an answer to above problem. Hence, the present invention is developed in order to give better and effective fertilizer composition comprising sufficient primary nutrients as well as micronutrients for crop management with cationic liquid, water-soluble fertilizer composition without undesirable alkali content such as Sodium (Na) and Chlorine (Cl) at neutral pH for maximum plant availability of Nitrogen, Phosphorous and Potassium source. Additionally, the present invention fertilizer is comprising of humectant, preservative and emulsifier combination that prevents undersaturation of liquid composition at lower atmospheric temperature (below 2 ºC) or higher atmospheric temperature (above 35 ºC). Additionally, the better absorption of available nutrients (Macronutrients as well as Micronutrients) to the plant has been assessed with the help of in-situ preparation of water soluble form of a metallic nanoparticle based formulation which increases absorption of metal ions into the plant. Therefore, the present invention provides a novel cationic liquid, Sodium and Chloride free, 100% water-soluble fertilizer in liquid form composition comprising different concentrations of primary nutrients selected from Nitrogen, phosphorous and Potassium, using preparation of water soluble cationic agents from the primary nutrients sources along with other essential micronutrients like Zinc (Zn), Iron (Fe), Copper (Cu), Manganese (Mn), Calcium (Ca), Magnesium (Mg). These all are micronutrients are in the form of chelated complex with Ethylenediaminetetraacetic acid (EDTA) and salts of Molybdenum (Mo) and Boron (B) without any risk of scorching/phytotoxicity and to give better yield with appropriate application rate. The present invention also provides a process of preparation of said novel cationic liquid, Sodium and Chloride free, 100% water-soluble fertilizer in liquid nanoformulation composition comprising different concentrations of primary nutrients selected from Nitrogen, phosphorous and Potassium, using preparation of water soluble cationic agents from the primary nutrients sources, additional excipients for stabilization of saturated solutions along with other essential micronutrients. OBJECTIVES OF THE INVENTION It is an objective of the present invention to develop a Sodium (Na) and Chlorine (Cl) free and 100% water soluble fertilizer nano-formulation having possible percentage of available Nitrogen (N), Phosphorous (P) and Potassium (K).

It is another objective of the present invention to provide a cationic liquid Nitrogen- Phosphorous-Potassium (N-P-K) based fertilizer which can also be used to control the salinity of soil using electrostatic interactions among nutrients and charged cationic species. Another objective of the present invention is to provide additional Micronutrients Zinc (Zn), Iron (Fe), Copper (Cu), Manganese (Mn), Calcium (Ca), Magnesium (Mg) - all are EDTA Chelated form with Molybdenum (Mo) and Boron (B) to correct the related Micronutrient deficiencies and enriching the crops and plants through foliar and soil application. Further objective of the present invention is to provide a process for preparation of a Sodium (Na) and Chlorine (Cl) free and 100% water soluble fertilizer having highest or equal possible percentage of available Nitrogen (N), Phosphorous (P) and Potassium (K) and having neutral pH value.

Yield (q/ha): The weight of fruits harvested in each picking from each net plot were recorded and totaled up plot wise to get yield per plot. This was converted hectare basis. Number of effective root nodules at flowering stage:Uprooted the selective plants carefully and removed the soil by tap water. Count each effective root nodules per plant. Yield attributes and yield studies: Five plants were randomly selected from each net plot for post-harvest studies such as number of pods plant-1, weight of pod-1, grain weight plant-1, test weight (g), grain and straw yield (q ha-1). Number of pods plant -1: All the pods from five randomly selected plants were counted separately after harvest and the average number of pods plant-1was worked out. Weight of pods pod-1(g.): At harvest, the weight of pods of five observational plants was recorded. Then weight of pods plant-1 was worked out. Grain weight plant-1(g.): The total grains obtained from every observation plant were weighed separately on analytical weighing balance and mean value was calculated for obtaining the weight of grains (g.)green pod weight of five randomly select plants was recorded from each plot. Test weight (g): From the composite seed of net plot 100 seeds were counted and weighed on analytical weighing balance and values were recorded. Grain yield (q ha-1): The produce was dried in sun for a week. After harvesting, the grains were cleaned of dried leaves, soil and other foreign material. The grain yield net plot-1 was recorded and then converted on hectare basis by multiplying with hectare factor. Straw yield (q ha-1): After removing the grain from pods, the stalks along with empty pods were dried in the sun. Upon drying, the weight of the bundle of stalk per plot was recorded. the weight per plot was transformed into hectare basis by utilizing hectare factor.
