Symposium for the Use of Organic Soil Amendments

The Symposium for the Use of Organic Soil Amendments (SUOSA) will take place on the Southern Gold Coast from 16 to 18 September 2025, bringing together experts from agriculture, environmental sciences, economics, and policy to discuss the benefits, challenges, and future directions for the use of organic soil amendments in agricultural and horticultural production systems.

This multi-disciplinary event will explore the agronomic, environmental, societal, regulatory and policy dimensions of using both solid and liquid organic amendments, which include raw or processed animal manures, agricultural residues, food and fibre processing residues, and urban organic residues, and where processing can include composting, pyrolysing, drying, digesting, insect farming, pelletising, granulating, value adding, etc. Discussions will address nutrient management, soil health, carbon sequestration, circular economy, regulatory frameworks, and farmer benefits and adoption.

With contributions from leading researchers, government policymakers, industry experts, and producers, SUOSA 2025 aims to foster collaboration and inform real-world strategies for sustainable soil management and farming systems.
