I. Introduction

As agricultural policies continue to prioritize green, high-efficiency, reduction-oriented, and synergistic approaches in 2026, fertigation technology is rapidly expanding across China. This policy environment has created a favorable window for the promotion of liquid fertilizers. Changzhou Jiayuan Chemical Co., Ltd. has closely followed the transformation trend in agriculture, focusing on the liquid fertilizer sector and introducing UAN (Urea Ammonium Nitrate solution) as one of its core products to the market.

II. Core Competitive Advantages of UAN

Changzhou Jiayuan Chemical's UAN product contains three forms of nitrogen: nitrate nitrogen, ammonium nitrogen, and amide nitrogen. The synergistic interaction of these three forms gives UAN both quick-acting and prolonged characteristics—a core advantage that traditional single-form nitrogen fertilizers lack.

UAN significantly boosts crop yields. In field crops such as corn and wheat, yield increases of 10%–15% have been observed, while in vegetables, the increase can reach 10%–30%. Based on a synergistic formulation of the three nitrogen forms, Changzhou Jiayuan Chemical's UAN helps growers achieve higher yield returns with lower input.

III. Typical Application Scenarios of UAN

Field crop applications – example: In corn grown in the semi-arid region of Northeast China using shallow-buried drip irrigation, UAN application achieved a 2.02% yield increase while effectively reducing residual inorganic nitrogen in deeper soil layers and minimizing nitrogen losses. In wheat–corn rotation systems, UAN applied as a topdressing via drip irrigation enables precise nutrient application, supplying nitrogen during critical growth stages to promote plump grains.

Cash crops and precision agriculture scenarios: For cash crops such as vegetables and fruit trees, the yield-enhancing benefits of UAN are even more pronounced. Changzhou Jiayuan Chemical's UAN product is compatible with fertigation systems, allowing low-volume, high-frequency precision fertilization, effectively preventing quality degradation in cash crops caused by uneven nutrient supply.

IV. Changzhou Jiayuan Chemical – A Stable UAN Supply Platform

Leveraging a well-established production system and a professional service team, Changzhou Jiayuan Chemical's products now cover multiple major planting regions across China, while steadily expanding into overseas markets through formal trade channels. With consistent product quality and a responsive technical service system, the company has earned high praise from numerous agricultural enterprises and distributors.

V. Outlook

Changzhou Jiayuan Chemical will continue to focus on refined upgrades of UAN and its liquid fertilizer portfolio, continuously optimizing product formulations and user experience. The company is committed to providing global growers with efficient and reliable nitrogen solutions, empowering green and sustainable agricultural development.
