High-efficiency urea combats fog and haze; it significantly reduces ammonia emissions! Author/Source: Xinlianxin Agricultural Inputs News Date: 2020-09-13 Clicks: 15 China emits 12–15 million tons of ammonia per year, with an emission intensity that is 4–5 times higher than that of the EU and the US. Of these, nearly 90% of ammonia emissions come from agricultural sources, with the extensive use of nitrogen fertilizers in agriculture being the main cause of ammonia pollution. In recent years, atmospheric environmental issues have attracted considerable attention; thus, the importance of research on ammonia emissions has become increasingly evident. It is particularly crucial to objectively and scientifically explore ways to reduce the intensity of agricultural ammonia emissions and mitigate agricultural non-point source pollution. The North China Plain and the middle and lower reaches of the Yangtze River are areas with high ammonia emissions. To understand the impact of new fertilizers containing urease inhibitors on air pollution as well as their effect on increasing crop yields, from 2019 to 2020, the Agriculture and Rural Affairs Bureau of Handan City in Hebei Province, the Handan City Ecology and Environment Bureau, and the research team led by Academician Zhang Fusuo from China Agricultural University collaborated to carry out a research project titled “Control of agricultural non-point source pollution to reduce ammonia emissions in agriculture.” Trials of these new fertilizers containing urease inhibitors were conducted on 16,000 mu of wheat-corn fields in Quzhou County, providing a basis for their wider adoption in the future. On September 10, the “Handan City Conference on Reducing Fertilizer Use while Improving Efficiency and Cutting Ammonia Emissions” was held in Quzhou. This conference was organized by the Soil and Fertilizer Station of the Handan City Agriculture and Rural Affairs Bureau, and was hosted by the Quzhou County Agriculture and Rural Affairs Bureau as well as the Quzhou Experimental Station of China Agricultural University. More than 100 participants attended, including leaders from the agricultural and rural affairs bureaus of various counties (cities, districts) in Handan City, directors of soil and fertilizer stations, professors from China Agricultural University, as well as large-scale farmers from those counties (cities, districts). They jointly observed the effects of applying a new type of nitrogen fertilizer containing urease inhibitors on corn, and exchanged ideas on how to further promote efforts to reduce ammonia emissions in agriculture. 01 Reducing ammonia emissions in agriculture is an urgent task; new, high-efficiency nitrogen fertilizers show significant effectiveness in suppressing ammonia volatilization. Reducing ammonia emissions is part of the trend toward sustainable agricultural development. The research project on \"Controlling agricultural non-point source pollution to reduce ammonia emissions\" was carried out in Quzhou, where demonstrations of ammonia emission reduction were conducted on 16,000 mu of land across 4 towns and villages—Quzhou Town, Disiutuan Town, Liyue Township, and Baizhai Town—as well as 2 cooperatives. Just in May this year, reporters at the \"Henan Heart-to-Heart Fertilizer Reduction and Efficiency Improvement sowie Demonstration and Training Session on New Types of Fertilizers\" organized by the Agriculture and Rural Affairs Bureau of Quzhou County learned that when used with wheat, new types of fertilizers containing urease inhibitors reduce ammonia emissions by 39%-85% compared to ordinary urea fertilizers. On September 10, the reporter returned to Quzhou and, along with leaders from various departments of the Municipal Bureau of Agriculture and Rural Affairs as well as agricultural experts and professors, investigated the effectiveness of new fertilizers containing urease inhibitors when used on corn. On-site testing of ammonia volatilization (urea SuperControl on the left, ordinary urea on the right). At the observation site, Niu Xinseng, a senior agronomist at the Quzhou Testing Station, Professor Liu Xuejun from China Agricultural University, and Dr. Xu Wen from China Agricultural University conducted actual measurements of the ammonia volatilization from the high-efficiency urea produced by Henan Xinlianxin Chemical Industry Group Co., Ltd. (hereinafter referred to as Xinlianxin Group) and ordinary urea. The results showed that under conditions where the application rate of nitrogen fertilizer was 10.4 kg of nitrogen per mu at demonstration sites such as Wangzhuang in Quzhou County, the ammonia volatilization loss in the conventional nitrogen fertilization treatment amounted to 1.51 kg of nitrogen per mu, accounting for 14.5% of the total amount of fertilizer applied ； The ammonia volatilization loss under the treatment with the new nitrogen fertilizer was 1.15 kilograms of nitrogen per mu, accounting for 11.1% of the total amount of fertilizer applied. Under the same nitrogen fertilizer application rate, the ammonia volatilization rate under the new fertilizer treatment was lower than that under the conventional fertilizer treatment. Professor Liu Xuejun said that at present, the spatiotemporal distribution of ammonia emissions is unclear, making emission reduction difficult and technological solutions lacking; urgent research is needed. The foundation for reducing ammonia emissions in agriculture is weak and the task is challenging, so there is an urgent need to develop key technologies for such reduction. The new fertilizer product developed and promoted by Xinlianxin—Chaokongshi High-Efficiency Urea—contains two active ingredients. It suppresses ammonia volatilization by over 50%, reduces fertilizer losses, and improves the utilization efficiency of nitrogen fertilizers. While ensuring crop yields, it also cuts ammonia emissions by more than 50%. It has played an important role in reducing ammonia emissions in agriculture, ensuring agricultural ecological safety while also protecting the environmental ecosystem. 02 Controlling emissions of ammonia from agricultural sources: Xinlianxin high-efficiency urea helps reduce ammonia emissions nationwide. After witnessing the significant effects of new nitrogen fertilizers containing urease inhibitors on corn, the group visited the 300-acre experimental demonstration site at the Quzhou Experimental Station. Zhang Hongyan, deputy director of the Quzhou Experimental Station of China Agricultural University, provided a detailed overview of the station’s activities related to monitoring atmospheric nitrogen deposition, meteorological observations, and the restoration of natural vegetation, enabling the attendees to gain a more comprehensive understanding of the implementation of projects aimed at reducing ammonia emissions from agriculture. At the seminar site, the Hanan City Agriculture and Rural Affairs Bureau held this \"Observation and Discussion Meeting on Projects to Reduce Fertilizer Use and Improve Efficiency while Cutting Ammonia Emissions in Hanan City\". By visiting the demonstration area in Quzhou County for the project aimed at reducing agricultural ammonia emissions through the control of agricultural non-point source pollution, and by observing the effects of new urease-inhibiting nitrogen fertilizers when used on corn, participants exchanged ideas on how to further advance efforts to reduce agricultural ammonia emissions. At the seminar, Duan Yunlong from the Agriculture and Rural Affairs Bureau of Quzhou County pointed out that since the beginning of this year, taking the opportunity of building a **-level green pilot zone, Quzhou County has adhered to the principles of cost reduction and efficiency improvement, quality enhancement and consumption reduction, resource conservation, and environmental friendliness. With a focus on promoting new types of fertilizers containing urease inhibitors, the county has achieved notable results in transforming fertilization practices, improving the efficiency of fertilizer utilization, and reducing ammonia emissions in agriculture. Duan Yunlong, Secretary and Director of the Agriculture and Rural Affairs Bureau of Quzhou County, delivered a speech. Professor Liu Xuejun from the Quzhou Experimental Station presented a report on ammonia emission reduction data. Zhang Hongyan, Deputy Director of the Quzhou Experimental Station at China Agricultural University, explained the progress in implementing ammonia emission reduction projects. Ding Hui, Senior Manager at BASF, gave a presentation. Hao Liyan, Section Chief at the Provincial Agricultural Technology Extension Station, offered specific suggestions regarding the reduction of fertilizer use while improving its efficiency. Chen Tao, Deputy Director of the Agriculture and Rural Affairs Bureau of Handan City, delivered a concluding speech. \"At present, farmers have a much stronger awareness of applying fertilizers scientifically; there is also a greater emphasis on using new, high-efficiency and organic types of fertilizers. The methods of fertilization have undergone significant changes, and fertilizer utilization rates are steadily increasing. However, it is still important to focus on the key technologies related to reducing fertilizer use while enhancing its efficiency.\" ”Hao Liyan, section chief at the Hebei Provincial Agricultural Technology Extension Station, said that accelerating the transformation of ways in which fertilizer resources are utilized, paying attention to agricultural environmental pollution, reducing the amount of fertilizers used, promoting projects aimed at reducing ammonia emissions in agriculture, and widely promoting new types of efficient nitrogen fertilizers have all contributed to ensuring agricultural ecological safety. Jia Xinchao, assistant to the general manager of Xinlianxin Group, delivered a comprehensive report on the research, development, production, and promotion of new types of fertilizers. At the meeting, Jia Xinchao stated that as early as 2012, Xinlianxin Group was the first in the industry to introduce the brand concept of \"high-efficiency fertilizers for China.\" The company increased its efforts in researching new products and forged strategic partnerships with scientific research institutions such as the Chinese Academy of Sciences and the Chinese Academy of Agricultural Sciences to jointly develop and promote environmentally friendly, high-efficiency fertilizers, thereby helping farmers increase their yields and incomes and contributing to the sustainable development of agriculture. Jia Xinchao explained that China has high levels of ammonia emissions from agriculture, and the areas with high emissions overlap significantly with those suffering from severe air pollution, which is one of the main causes of smog. In the field of crop cultivation, there is an urgent need for technologies such as precise nitrogen reduction and methods to slow down ammonia release. To date, Xinlianxin Group has promoted over 16,000 tons of Super-Kongshi urea. This has played a catalytic role in reducing ammonia emissions from agricultural sources nationwide, making it possible to address the prevention and control of air pollution in farmland through technological means. The initiative thus yields significant ecological benefits. At the same time, Xinlianxin Company focuses on developing humic acid fertilizer products for different regions and crops, with the goals of reducing fertilizer use, increasing efficiency, and improving product quality, thereby driving innovative development in the industry’s products. Leaders from the agricultural bureaus of various counties and districts exchanged views on the progress of agricultural ammonia emission reduction projects and the specific methods for reducing fertilizer use while improving its efficiency. They clarified their approaches, identified key priorities, and proposed strategies to further promote effective efforts to reduce fertilizer use and enhance its efficiency across the city, thereby fostering green and sustainable agricultural development throughout the region. At the end of the meeting, it was emphasized that all counties (cities, districts) should raise their awareness further, enhance their sense of responsibility and urgency in working to reduce the use of fertilizers and lower ammonia nitrogen emissions. They need to strengthen leadership, focus on key areas, and address critical issues. Technical outreach and training programs aimed at grassroots levels and farmers should be carried out in depth. Technical experts should continue to provide guidance and services directly in the fields, ensuring that various key technologies are properly implemented. This will help advance projects aimed at reducing ammonia emissions in agriculture and promote its green, healthy, and sustainable development.
