Description:FIELD OF INVENTION
The present invention is related to liquid based nitrogenous fertilizer having a water-based solution, with higher nitrogen content. More particularly, the present invention discloses solution Liquid Nitrogenous Fertilizer having at least total Nitrogen of 35 % w/w to 40% w/w.
BACKGROUND OF INVENTION
Nitrogen is a vital nutrient for plant growth and plays a significant role in agricultural productivity. It is an essential component of proteins, nucleic acids, and chlorophyl, which are essential for plant development and photosynthesis. However, nitrogen in its natural form is often unavailable or present in low concentrations in the soil, necessitating the use of fertilizers to meet plant’s nitrogen requirements.
Traditionally, solid fertilizers, such as granular or powdered formulations, have been widely used in agriculture. While it has several advantages, there are also some disadvantages associated with its use:
Nitrogen Loss: Urea is susceptible to nitrogen loss through volatilization, especially when applied to the soil surface without incorporation. This can result in a significant amount of nitrogen being lost to the atmosphere as ammonia gas, reducing the fertilizer's efficiency and contributing to environmental pollution.
Environmental Impact: Excessive or improper use of urea N 46 can lead to nitrogen runoff and leaching, which can contaminate water bodies and contribute to eutrophication. Eutrophication can cause algal blooms, deplete oxygen levels in water, and harm aquatic ecosystems.
Uneven Distribution: If not applied and distributed properly, traditional urea granules or prills may lead to uneven nutrient distribution in the soil, resulting in some areas receiving excessive nitrogen while others remain deficient.
Urea Burn: Urea N 46 in its solid form can cause "urea burn" if it comes into direct contact with plant tissues, particularly leaves and stems. This burn can damage the plant and hinder growth.
Fast Release: Traditional urea releases nitrogen rapidly after application, which may not align with the nutrient demands of certain crops. The quick release can lead to nutrient wastage and potential leaching if not taken up by plants promptly.
Nutrient Imbalance: Urea N 46 provides only nitrogen as a nutrient and lacks other essential elements like phosphorus and potassium. Overreliance on urea without proper consideration of other nutrients can lead to nutrient imbalances in the soil and affect crop health.
Limited Long-Term Effect: As a water-soluble fertilizer, urea N 46 can be prone to leaching from the root zone over time, which reduces its long-term effectiveness compared to slow-release or controlled-release fertilizers.
While effective, these solid fertilizers often have limitations in terms of nutrient distribution and application efficiency. Uneven distribution of solid fertilizers results in localized nutrient imbalances, reducing crop yield and potentially leading to environmental issues like runoff and leaching.
While fertilizers are used; the solid urea undergoes a hydrolysis process in the soil, where it is converted into ammonium and bicarbonate ions. The ammonium is further converted to nitrate by soil microorganisms, making it available for plant uptake. This process may take some time, and there is a risk of nitrogen loss through volatilization during the hydrolysis phase. If urea comes into direct contact with plant tissues, it can cause ammonia toxicity and "urea burn," which damages leaves and stems. If urea is not absorbed by plants or converted into stable forms in the soil, it can be susceptible to leaching with water movement through the soil profile or runoff during heavy rain. Leaching and runoff leads to nitrogen pollution in water bodies and contribute to environmental issues such as eutrophication. Uneven distribution results in some areas of the field receiving too much nitrogen while other areas do not receive enough, leading to inconsistent plant growth and lower yields.
To overcome these challenges, liquid fertilizers have gained popularity due to their advantages in nutrient distribution, ease of application, and versatility. Liquid fertilizers offer uniformity in nutrient distribution, ensuring that plants receive a consistent supply of nutrients.
Water-based nitrogenous liquid fertilizers provide an efficient means of delivering nitrogen to plants. These fertilizers typically consist of a nitrogen source, water, and various additives that enhance the fertilizer's performance and stability. The nitrogen source can include compounds such as ammonium nitrate, ammonium sulfate, urea, and other nitrogen-containing substances. The water serves as the carrier for the nutrients, facilitating their absorption by plant roots and ensuring even distribution throughout the soil.
Developing a reliable and efficient method for producing water-based nitrogenous liquid fertilizers is essential to meet the growing demand for high-quality fertilizers that promote sustainable agriculture. Such a method should ensure the efficient utilization of nitrogen, offer customizable formulations to meet specific crop requirements, and enable easy application through various irrigation systems. By addressing these needs, the proposed method for producing water-based nitrogenous liquid fertilizer aims to contribute to improved crop productivity, environmental sustainability, and overall agricultural efficiency.
The present invention has unique aspect of usage of Dicyandiamide, a nitrification inhibitor with higher nitrogen content of at least 35 % w/w of total nitrogen to 38% w/w of total nitrogen. The Patent No: WO2016064973, KR20230025865 and CS247314 claims a composition using Dicyandiamide used as a liquid nitrogen fertilizer. However, none of these patent claims shows either total nitrogen content of exceeding beyond 35 % w/w or the efficacy of Dicyandiamide in terms to slowing down nitrification process. The patent no: IN202211013205 also discloses a method of manufacturing Liquid fertilizers containing high nitrogen level it has specifically claimed that the nitrogen content has not exceeded beyond 35 % w/w of total nitrogen. The patent no: IN202247051281 discloses organic water soluble fertilizer with humic properties is claimed to have 3% w/w to 11% w/w of total nitrogen with respect to dry nitrogen weight and this fertiliser is basically produced in solid form.

OBJECT OF THE INVENTION
The main objective of the present invention is to produce a liquid fertilizer having a water-based solution with higher nitrogen of at least 35 % w/w of total nitrogen to 40% w/w of total nitrogen.
Another object of the present invention to provides much needed Nitrogen to the crop in a relatively easier process by combining a formulation that includes the benefits of conventional fertilizers while reducing the dependency.
Another major object of the present invention is related to usage of Dicyandiamide as nitrification inhibitor. It is a chemical compound that is added to fertilizers to slow down or inhibit the process of nitrification in the soil.
Yet another objection of the present invention is to improve the efficiency of nitrogen fertilizers by reducing nitrogen losses from the soil. Having combined Urea, Nitric acid, Dicyandiamide, Organic Components, this invention aims to make optimum availability of nitrogenous nutrients to the crop without the hassle of using different fertilizers. The Liquid Nitrogenous Fertilizer brings about a welcome change for the farmers who have been using conventional nitrogenous fertilizers like urea and ammonium nitrates etc. incoherently without considering the actual needs of the crop at hand. Since nitrogenous fertilizer is in a liquid form, it helps in targeted application of the same to the crops, hence avoiding a lot of, unnecessary spillage and waste which happens while using the typical form of application i.e. Solids.
