202311th International Symposium on
Plant-Soil Interactions at Low pH (PSILPH)

Organized by International Steering Committee of PSILPH
Institute of Soil Science, Chinese Academy of Sciences
Soil Science Society of China

October 16-21, 2023 (GMT+8). Nanjing, China


Approximately 30% of the world’s total land area consists of acid soils, and it has been estimated that over 50% of the world’s potential arable lands are acidic. In China, acid soils are primarily located in the southern subtropical and tropical regions, covering an area of 2.18 × 106 km2 and accounting for approximately 22.7% of the country’s total land area. To discuss the problems of soil acidification, connect scientists and to disseminate research results, the First International Symposium on Plant-Soil Interactions at Low pH (PSILPH) was successfully held in Canada in 1987. Since then, the symposium has been run every 3-4 years in different countries, including USA (1990), Australia (1993), Brazil (1996), South Africa (2001), Japan (2004), China (2008), India (2012), Croatia (2015) and Malaysia (2018). The 11th PSILPH meeting was originally scheduled to be held in October 2021, Nanjing, China, but due to the global COVID-19 pandemic, it has to be postponed for two years. After discussed with International Steering Committee, we are now pleased to announce that the 11th PSILPH meeting will be held in Nanjing on site in October, 2023. October is a very pleasant time of year to visit Nanjing. We are looking forward to having you here to share most exciting researches on acid soils.

Symposium Objectives

The 11th international Symposium on Plant-Soil Interactions at Low pH will be a platform for exchanging and disseminating knowledge and experience, ideas and results on all research fields associated with soil acidity including both crop and forest lands. It will also provide a good opportunity for promoting internationalization and friendships among researchers and professionals. The theme of the 11th PSILPH symposium will be “The Sustainable Utilization of Acid Soils”.
