Innovative Trend of Efficient Fertilizers with Effective Nutrients
At the FSHOW Forum 2021 in Shanghai, research fellow Mr. Zhao Bingqiang, Chief Scientist of Agricultural Resources and Regional Planning of CAAS, made a theme report on “Innovation and industrial upgrading of fertilizer products”. Research fellow Mr. Zhao Bingqiang introduced the related issues of upgrading fertilizer industry. Based on that, he gave an introduction of the relevant issues of chemical fertilizer product innovation.
Research Mr. Zhao Bingqiang pointed out that the two goals of chemical fertilizer product innovation are the effect of invalid nutrients and efficiency of effective nutrients, the later being the upgraded stage of the former. The effect of invalid nutrients means transforming the invalid nutrient form in the fertilizer resource into effective nutrient form. The efficiency of effective nutrients means that the nutrient of the product can not only be absorbed and utilized, but also be used efficiently. Then, he summarized three technical trends of efficiency of effective fertilizer nutrients. The first technology trend is from passive control fertilizer to active control fertilizer; the second one is from single regulation of macro elements to multi-element comprehensive regulation; The third one is from adjusting fertilizer itself to comprehensive control of fertilizer-crop-soil system.
Afterwards, Mr. Zhao introduced several stages of chemical fertilizer industry upgrading driven by innovation of chemical fertilizers. According to his words, the upgrading of chemical fertilizer industry is from initial fertilizer to low concentration fertilizer, and then from low concentration fertilizer to high concentration fertilizer. He pointed out that the goal of “Fertilizer Industry 4.0” is green and efficient fertilizer, and then the green fertilizer system is divided into five parts, namely, green raw materials, green manufacturing, green products, green circulation and green application. He analyzed that the advantages of each part one by one in detail. The research fellow believed that the green fertilizer system can help to realize the Harmonious Circulation among “fertilizer-soil-plant-environment”, and emphasized that green high-efficiency fertilizer has the advantages of high yield and high quality, fertilizer cultivation, soil protection and environmental protection, etc.
