Description:FIELD OF INVENTION
The present invention is related to Emulsion-based liquid fertilizer. More particularly, the present invention discloses emulsion-based liquid fertilizer using carbomer that contains nitrogen, phosphorous and potassium (NPK) having at least total content of 30% w/w to 65% w/w.

BACKGROUND OF INVENTION
Nitrogen, phosphorus, and potassium (NPK) are essential macronutrients required for optimal plant growth, development, and productivity. These nutrients play vital roles in various physiological processes within plants, such as photosynthesis, energy transfer, and cell division.
In agricultural practices, NPK fertilizers are commonly used to replenish soil nutrient levels and enhance crop yields. Traditionally, NPK fertilizers are available in solid forms, including granules, powders, and pellets. However, these conventional solid fertilizers have several limitations, including uneven distribution, leaching, and wastage.
Solid NPK fertilizers often suffer from uneven distribution when applied to the soil surface, leading to spatial variability in nutrient availability for plant roots. This non-uniform distribution results in patchy growth and yield disparities within the field. Moreover, solid fertilizers are susceptible to leaching, especially in regions with heavy rainfall or over-irrigation. Leaching leads to nutrient runoff into water bodies, causing environmental pollution and nutrient loss from the agricultural ecosystem. Additionally, solid fertilizers require multiple applications throughout the growing season to meet the dynamic nutrient demands of crops, leading to increased labor and resource costs for farmers.
To address these challenges, liquid fertilizers have gained popularity due to their advantages in nutrient delivery, application flexibility, and reduced environmental impact. Liquid NPK fertilizers offer several benefits over solid formulations, including improved nutrient absorption, uniform distribution, and reduced leaching.
However, existing liquid fertilizer formulations may encounter stability issues, nutrient segregation, and inefficiencies in nutrient delivery to plants.
Liquid fertilizers offer uniformity in nutrient distribution, ensuring that plants receive a consistent supply of nutrients. These fertilizers typically consist of a nitrogen, phosphorous and potassium source, water, and various additives that enhance the fertilizer's performance and stability.
