Changzhou Jiayuan Chemical: A Full-Category Liquid Fertilizer Matrix Empowers High-Quality Development of Modern Agriculture with UAN as the Core ( Part 1 )

With agricultural policies continuing to favor green, efficient, and cost-effective practices in 2026, and the rapid popularization of integrated water and fertilizer technology, liquid fertilizers, with their core advantages of high efficiency, environmental friendliness, easy absorption, and suitability for precise fertilization, have become a core support for the transformation of modern agriculture, and the market size is steadily expanding.

As a strong company with many years of experience in the chemical industry, Changzhou Jiayuan Chemical closely follows industry trends, focusing on the research, development, production, and supply of liquid fertilizers. It has built a product matrix covering five core categories, using high-quality products and professional services to help farmers reduce costs and increase efficiency, promote the green and sustainable development of agriculture, and demonstrate the responsibility and commitment of a chemical enterprise.

Among Jiayuan Chemical's liquid fertilizer product portfolio, UAN (urea ammonium nitrate solution) stands out as a core star product, leveraging its unique advantage of synergistic effects of three nitrogen compounds to become the preferred solution for efficient nitrogen supplementation in agricultural production. This product is scientifically formulated with urea, ammonium nitrate, and water, conforming to the industry standard "Urea Ammonium Nitrate Solution" (NY2670-2020). It offers nitrogen content in three mainstream grades: 28%, 30%, and 32%, maintains a stable pH of 6.5-7.5 (neutral to slightly alkaline), and is a colorless or light yellow transparent liquid. It is stable under normal pressure with no risk of explosion, is 100% water-soluble, and has extremely low corrosiveness. Different concentration grades are suitable for different climate zones, with UAN-32 exhibiting a salting-out temperature as low as -18℃, ensuring safe use in low-temperature regions.

Compared to traditional solid nitrogen fertilizers, UAN has significant advantages: Its production process eliminates the drying and granulation steps, resulting in 31% lower energy consumption than solid urea and a reduction of 0.33 tons/ton in CO₂ emissions, embodying the concept of green production; its nitrogen utilization rate is as high as 90%, 4-5 times that of traditional urea, reducing nitrogen leaching loss by 40% and lowering ammonia volatilization pollution; it has excellent compatibility, allowing for mixing with phosphorus and potassium fertilizers, micronutrients, and pesticides, and is compatible with drip and sprinkler irrigation systems, enabling "one-stop" fertilization, reducing labor input, and is widely used in field crops such as wheat, corn, and cotton, as well as cash crops such as vegetables and fruit trees, promoting increased crop yield and quality. Specifically, it can increase yields by 10%-15% in corn and wheat, and by 10%-30% in vegetables.
