A Milestone in the R & D of Yishizhuangs New Fertilizers - The Successful Trial Run of Slow - Release and Controlled - Release Fertilizers

The Birth of Yishizhuang's Slow - Release and Controlled - Release Fertilizers

In recent years, with the pursuit of high - yield, high - efficiency, ecological, and simplified agricultural cultivation techniques, slow - release and controlled - release fertilizers that can save labor and time and improve fertilizer utilization have emerged. In June 2023, the research and development of new fertilizers by Hubei Yishizhuang Agricultural Technology Co., Ltd. reached a new milestone - the successful trial production of slow - release and controlled - release fertilizers. The company's R & D of slow - release and controlled - release technologies and products conforms to the new situation of China's agricultural development and meets the new demands of industrial upgrading. It is another major scientific and technological breakthrough after the three major series of products, namely special formula fertilizers for crops, bio - functional organic fertilizers, and tower - type organic - inorganic water - soluble fertilizers.

"Installing a Switch" for the Rational Release of Fertilizer Nutrients

The technology of slow - release and controlled - release fertilizers is to put a polymer coating on fertilizer granules, enabling the nutrients of the fertilizers to penetrate the coating layer and be released at a controlled release rate and release period.

Letting technological innovation take root in every link of the enterprise's growth is the core of Yishizhuang's strategic development. As early as 2018, Yishizhuang began to explore adding controlled - release components on the basis of the slow - release function of special formula fertilizers for crops to precisely improve fertilizer utilization. With the continuous upgrading of new fertilizer products, relying on the experience accumulated in slow - release fertilizer technology in the early stage, and with the technical guidance of experts related to the production process of new fertilizers from universities and research institutes, and in cooperation with the Japan Nohyaku Association and Nissho Iwai Toyama Co., Ltd., Yishizhuang finally introduced the internationally leading Japanese slow - release and controlled - release technology to further optimize the regulation of nutrient release on the basis of slow - release.

After investigation, research, small - scale trial production, and experimental demonstrations, the company upgraded the coating materials and optimized the production line. It successfully trial - produced slow - release and controlled - release urea and slow - release and controlled - release nitrogen - phosphorus - potassium compound fertilizer products with release periods of 40 days, 60 days, 80 days, 100 days, 120 days, 140 days, 160 days, and 240 days. After inspection, the release periods meet the requirements of national standards. At present, the company has the ability to produce slow - release and controlled - release fertilizer products with independent intellectual property rights and its own brand.

Slow - Release and Controlled - Release Fertilizers: The "Vanguard" of the Company's Strategic Development

Low - carbon and high - efficiency have become the general trend of the development of the fertilizer industry. The company integrates its products into the product systems of special formula fertilizers for rape, rice, citrus, vegetables, tea, western melons, and muskmelons. A large number of experiments and demonstrations have proven that when controlled - release urea is applied with a 15% - 25% reduction in nitrogen, the yield does not decrease. In many cases, there is a significant yield - increasing effect, indicating that it can save labor and time and reduce fertilizers while increasing efficiency without increasing fertilizer input.

External issues such as food security, energy conservation, emission reduction, and modern agriculture have increased the demand for fertilizer innovation, bringing the slow - release and controlled - release fertilizer industry into a historical opportunity period of development. Yishizhuang will surely live up to expectations, conduct in - depth research on slow - release and controlled - release technology products, and contribute to the modernization of national agriculture and rural revitalization.
