The key to soil remediation lies in exploring and promoting effective models
The Action Plan for Soil Pollution Prevention and Control (known as the "Soil Ten Measures") was issued not long ago, and the government's efforts to tackle soil pollution can be described as unprecedented. So from which aspects should soil pollution prevention and control, and ecological protection and remediation proceed? What role and responsibility will relevant enterprises have in this action? What kind of fertilizer is the focus of future development?
Recently, in the Wintian Hall of the Key Laboratory of Efficient Irrigation-Drainage and Agricultural Soil-Water Environment in Southern China (Hohai University), Ministry of Education, located in Nanjing, Jiangsu Province, more than 300 industry representatives from home and abroad engaged in soil improvement and remediation, research, development and promotion of environmentally friendly fertilizers, as well as river and waterway management and water quality purification, attended the First China International Forum on Soil and Water Ecological Environment Remediation and Environmentally Friendly Fertilizers, to jointly discuss the major plans for soil and water ecological environment remediation, and jointly deliberate the opportunities and actions for enterprises in soil remediation after the promulgation of the "Soil Ten Measures."
The attending representatives believed that strengthening the safe use and risk control of soil, carrying out farmland soil treatment and remediation, and ensuring "safety on the tip of the tongue" are all the responsibilities and obligations of enterprises. However, the implementation and advancement of the "Soil Ten Measures" still require supporting policies, regulations, technologies, products and funds, and it is even more necessary to enhance risk control awareness. Exploring and promoting effective soil remediation models is key. Meanwhile, technologies and products related to soil improvement, remediation and ecological environment protection and treatment will usher in more room for development.
Ouyang Pingkai, chairman of the China Green Ecological Environment Remediation Alliance and academician of the Chinese Academy of Engineering, said that truly starting from the source of agricultural product planting to solve soil problems plays an important role in food safety and restoring the original ecological taste of agricultural products. Lin Xiangui, chairman of the National Technical Committee for Soil Quality Standardization, proposed in his special report "Innovating Organic Fertilizer Production Technology to Make Soil Healthier" at the forum that scientifically and rationally applying organic fertilizer is an important link in realizing the reuse and recycling of nutrient resources in agricultural systems, and is also a key measure to maintain and improve soil health quality.
Duan Jixian, former deputy director of the Planting Industry Management Department of the Ministry of Agriculture, Hu Shuwen, professor at China Agricultural University, Shao Xiaohou, professor at Hohai University, and other professionals respectively explained the effects of functional products in soil and water remediation and ecological environment protection from multiple perspectives, including the role of biological additives in improving fertilizer quality and efficiency, green remediation technology for saline-alkali land, and the application of effective microbial technology in water quality purification. Han Fengxiang, professor at Jackson State University in the United States, introduced the technologies, methods and results of American agriculture in heavy metal treatment.
Enterprises long engaged in soil improvement and remediation, such as Jiangsu Kebang and Hebei Silicon Valley, introduced their latest soil remediation products and scientific research results.
