Agricultural production in China has increased tremendously during the last thirty years, especially increased year by year during last 6 years. This was achieved via better farming practices and supporting policies as well as improved seeds, irrigation and fertilizer use.

With the increasing population and projected strong demand for food, fiber and fuel from agriculture in the future, and no waste land to spare for additional production, a much needed further refinement and optimization of fertilization practices is required. At the same time, there is compelling evidence for sub-optimal usage of nutrients: in many regions of China it is reported that nitrogen application far exceeds the needs, causing severe unbalanced fertilization. Potassium requirements in China are diverse: the fast growing fruit and vegetable sector need large amount of potassium, while potassium consumption in cereals and oil seeds is still low and in many cases below the optimal level.

Hence there is a need to optimize the use of potash in all sectors of the Chinese agriculture. By doing so, farmers will benefit from better utilization of precious irrigation water and nitrogen fertilizer, reduce the burden of reactive nitrogen on the environment and improve their income and profits.

The international symposium on "Management of Potassium in Plant and Soil Systems in China" will address the issues related to the role and benefits of potassium fertilizers in Chinese agriculture, focusing on chemical, physical and biological processes in soil and plants, farm management and economical application of fertilizers.

During the symposium, issues including soil fertility, quality of mineral fertilizers, efficient use of fertilizers and fertigation will be discussed. This event will be of interest to soil and plant nutrition scientists, agronomists, and extension officers from universities and research organizations, government offices, agribusinesses who share an interest in improving food production and quality in China. Invited speakers will include scientists from China and abroad. Poster presentations are open to all, and students are encouraged to participate and present research related/relevant to the themes of the symposium.

The sustainability of agricultural systems greatly depends on balanced fertilization to improve soil fertility for secure and sustainable food production. Potassium fertilizers play a crucial role in improving the quality and yields of crops and thus contribute to the welfare of farming communities. Water availability and high evaporation are other important parameters which affect productivity. The development of advanced technologies and fertilization practices is a priority to secure food production in the country, as well as a significant effort in education.
