Optimizing organic fertilization in Camargue rice farming

Organic fertilizers in rice paddies show rapid nitrogen mineralization under flooded conditions, similar to mineral fertilizers. A 2004–2006 study in Camargue, France, demonstrated that split application—starting at panicle initiation—improves efficiency and profitability for organic farmers. This strategy, aligned with conventional practices, enhances nutrient use and is economically viable with minimal additional field passes. Supports organic rice farming with evidence from paddy soil studies in Asia and fertilizer guidelines.
