Successful water-linked test run of the liquid calcium fertilizer testing apparatus developed by Yuxiang Populus euphratica – Author/Source: Yuxiang Populus euphratica – Date: 2022-04-28 – Clicks: 22. Recently, the water-linked test run of the liquid calcium fertilizer testing apparatus produced by Yuxiang Populus euphratica was a complete success. In line with the key measures for the transformation and development of the fertilizer industry outlined in the **Ministry of Industry and Information Technology’s Guidelines on Promoting the Transformative Development of the Fertilizer Industry**, the company continuously adjusts its product portfolio and focuses on developing efficient, environmentally friendly new types of fertilizers. In early April 2021, led by the company’s Technology Department, multiple departments including the Quality Management Department, Production Department, and Compound Fertilizer Workshop worked together to fully leverage the advantages of the existing *ao acid an products, while actively exploring and designing new processing procedures. In 2022, after multiple technical seminars and exchanges organized by various departments, and through efforts from everyone involved, ranging from laboratory simulations to actual pilot production, the pilot production plan was continuously refined. The optimal ratio for liquid calcium fertilizer was determined, thereby resolving various issues such as difficulties in controlling the pH value, the lack of pressure filtration equipment, slow filtration speeds, and poor performance. Thus, the hydraulic commissioning of the liquid calcium fertilizer experimental setup was a complete success, laying a solid foundation for the subsequent development of the liquid calcium fertilizer project. Liquid calcium fertilizer is a mixture of UAN solution (urea and ** solution) and calcium; it is 100% water-soluble and free of impurities. It is particularly suitable for drip irrigation, furrow application, and foliar spraying. The UAN solution has good compatibility and can be used together with other fertilizers and pesticides, saving water, time, and labor. The utilization rate of UAN liquid fertilizer exceeds 90%, which is four times that of traditional urea. It can effectively reduce nitrogen loss and water pollution, thereby achieving the goals of cost reduction, energy conservation, and environmental protection. The establishment of the liquid calcium fertilizer testing apparatus has effectively improved the enterprise’s production and operational capabilities. Next, Yuxiang Populus Euphratica Company will take this as an opportunity to intensify its efforts in the development and production of liquid calcium fertilizers, thereby improving the current situation of fertilizer shortages in southern Xinjiang and making greater contributions to the economic and social development of the region.
