[Fertilizer Efficiency] Over a hundred people gathered in Yutai, Jining, to witness the remarkable effectiveness of rice cultivation without supplemental fertilization.

Recently, the Lunan Branch of Nongda Fertilizer Co., Ltd., in collaboration with Jining Runnong Seed Industry, held demonstration events on Nongda’s no‑reapplication rice fertilizer at Tangma Town and Shiji Farm in Jining. More than 100 rice farmers from Yutai, Jining, attended to witness the remarkable performance of Nongda’s no‑reapplication fertilizer on rice crops.

Nongda rice’s no‑reapplication fertilizer is the culmination of Nongda Fertilizer Industry’s more than ten years of research, development, production, and promotion of controlled‑release fertilizers. According to reports, the resin‑coated urea produced by Nongda Fertilizer Industry boasts a nitrogen content as high as 45.6% and a controlled‑release period of two months.

Zhang Chengyin, Director of the North China Region at Nongda Fertilizer Co., Ltd., stated: “Our rice fertilizer that eliminates the need for topdressing offers two distinct advantages: first, its controlled-release formulation is highly precise, enabling it to align with the nutrient‑requirement patterns of rice at each growth stage and scientifically regulate nutrient release, ensuring optimal efficacy over an appropriate time frame; second, the fertilizer contains activated humic acid, which, when combined with chemical fertilizers, produces a synergistic effect—controlling nitrogen, promoting phosphorus uptake, activating potassium, prolonging fertilizer effectiveness, and enhancing fertilizer use efficiency. Moreover, humic acid serves as a natural plant growth regulator, stimulating crop physiological metabolism and fostering root growth and development. In addition, humic acid helps improve soil structure, promotes the formation of soil aggregate particles, and balances soil pH, water availability, nutrient status, air circulation, and temperature.”

Song Zhi, a senior researcher at Nongda Fertilizer Co., Ltd., explained that, under current practices, rice cultivation typically involves applying 50 kilograms of 15-15-15 compound fertilizer as a base application, followed by two to three topdressings during the tillering, jointing, and booting stages—each consisting of approximately 10 to 15 kilograms of urea. In contrast, the no‑topdressing system requires only a single mechanized base application before sowing or transplanting; no additional topdressing is needed. Compared with conventional fertilization, this approach reduces nitrogen fertilizer use by 20% while maintaining or even surpassing yields, thereby saving labor and easing the physical workload.

It is understood that, in recent years, Nongda Fertilizer Co., Ltd., building on its earlier research and field trials of controlled-release fertilizers for rice, has commissioned the Shandong Provincial Agricultural Technology Extension Station to establish ten demonstration sites across the province’s major rice-producing areas. These sites are located in Rencheng District and Yutai County of Jining City; Weishan County; Hedong District and Tancheng County of Linyi City; Junan County, Ju County, and Gaoqing County; Mudan District of Heze City; Jiyang County; Kenli County; and the Beihai Economic Development Zone of Binzhou City. The extension trials conducted at these sites have yielded promising results and have been well received by local agricultural technology stations and large-scale farmers. Compared with conventional fertilization, even with a 20% reduction in fertilizer application, yields increased by more than 5%, and net income per mu rose by over 100 yuan.

Dun Xichao, Marketing Manager at Shandong Runnong Seed Industry Technology Co., Ltd., speaks highly of Nongda Fertilizer’s no‑reapplication fertilizer. He notes that several pilot trials showed that other brands’ no‑reapplication products delivered results comparable to conventional compound fertilizers, falling short of the promised “no‑reapplication” benefit. In contrast, Nongda Fertilizer’s product boasts long-lasting efficacy, rapid seedling emergence, early tillering, early heading, and sustained yield‑boosting performance—yield increases exceeding 15%. It saves labor and reduces management concerns while delivering high yields. Farmers no longer need to worry about timing their applications; the product truly achieves the goal of eliminating the need for follow‑up fertilization.

Local rice farmers witnessed the tangible benefits of the no‑reapplication fertilizer technique and spoke highly of Nongda’s no‑reapplication fertilizer, expressing their willingness to adopt and promote it.

The convening of this observation meeting enabled more farmers to witness the tangible benefits of Nongda’s rice‑specific fertilizer‑free topdressing technology, while also accelerating the adoption of this approach in the Jining region. Moving forward, Nongda Fertilizer Industry will remain committed to its corporate mission of “helping more farmers achieve greater economic returns,” guided by the principle of “rooted in Nongda, nurturing the soil, balancing nutrition, and fostering harmony between soil and fertility.” The company will continue to innovate and promote cutting-edge products and advanced agronomic services, helping farmers boost crop yields and quality, increase their incomes, and contribute innovative solutions to China’s agricultural modernization, rural development, and the prosperity of farmers.
