Present invention also provides a process of preparation thereof. The present invention provides a liquid fertilizer having 100% water miscibility comprising of highest concentration of Nitrogen and micronutrient chelated fertilizer composition.
  • Plant nutrients are one of the environmental factors essential for crop growth and development. Nutrient management is crucial for optimal productivity in commercial crop production. Those nutrients in concentrations of 100 parts per million (ppm) in plant tissues are described as micronutrients and include iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), boron (B), chlorine (Cl), molybdenum (Mo), and nickel (Ni). Micronutrients such as Fe, Mn, Zn, and Cu are easily oxidized or precipitated in soil, and their utilization is, therefore, not efficient. Therefore, chelated fertilizers have been developed to increase micronutrient utilization efficiency.
  • Foliar application is done with spraying a mist of fine water droplets through small spray nozzles.
  • foliar applied fertilizers should soluble in water or dispersed in a such a good way that the spraying nozzles are not blocked.
  • Powder formulation are not perfectly homogeneous in the spray solution as it is being manually prepared in the field.
