Organized by International Union of Soil Sciences and Soil Science Society of China, the 23rd World Congress of Soil Science (WCSS2026) will be held in June 7-12, 2026 in Nanjing International Expo Center. World Congress of Soil Science (WCSS) is poised to be a landmark gathering for the global soil science community. Since its inception in 1927, WCSS has been convened every four years, serving as a pivotal scientific forum in the realm of soil sciences.
WCSS2026 theme, 'Soil and the Shared Future for Humanity' focuses on the importance of soil for our future, with a variety of arrangements including plenary session, parallel sessions, poster exhibition and soil judging contest. Tours will also be organized for participants to visit typical soils in combination with unique landscapes and cultural diversification as China is a vast country with rich soil resources.
Building on its longstanding legacy, the Congress has received 3338 abstracts from 96 countries for 138 sessions, aiming to attract more than 3500 participants globally. The sessions encompass the full spectrum of soil science, including fundamental soil processes, innovative monitoring technologies, policy frameworks, and community-engaged practices. By fostering international collaboration across academic, governmental, and industrial sectors, WCSS2026 aims to accelerate the translation of soil science into tangible sustainability outcomes, supporting global goals for food security, environmental protection, and climate resilience.
The Organizing Committee of the congress cordially invites global soil science communities, institutions in related fields and friends who care about soil health to actively engage in the congress and enjoy the early-bird registration before March 7th, 2026.
