Turkish scientists develop organomineral fertilizer from olive waste

Scientists in Turkey are developing a new generation of organomineral fertilizer derived from olive pomace, the waste residue left after olive oil production. The project is a collaborative effort between the Kırklareli Atatürk Soil, Water and Agricultural Meteorology Research Institute and Çanakkale Onsekiz Mart University, supported by TÜBİTAK and the General Directorate of Agricultural Research and Policies (TAGEM).

The process involves converting olive pomace into biochar, which is then combined with a locally patented compound designed to prevent rapid nitrogen loss in soil. This method aims to reduce the need for chemical fertilizers and lower greenhouse gas emissions, specifically nitrous oxide.

Field tests are currently underway on wheat and corn in Kırklareli and the Keşan district of Edirne. Researcher Dr. Mehmet Ali Gürbüz stated that wheat trials are complete, while laboratory analysis for corn is ongoing. The project is expected to be finalized by the end of 2026. Notably, the fertilizer is designed to be compatible with existing farming equipment, requiring no additional machinery for farmers.
