Video tutorial: Phosphorus recycling for organic agriculture
The CORE Organic II project Improve-P recently ended. Else Bünemann, Astrid Oberson and Kurt Möller from the Improve-P team summarized the project outcomes in a 30-minute video tutorial with the following eight chapters: Introduction, inventory of available technologies, P availability, risk assessment, life cycle assessment, regulations, stakeholder survey and conclusions.
Else Bünemann of FiBL introduces the video by explaining the relevance of phosphorus. She presents the results of a life cycle assessment, an analysis of different national regulations and a stakeholder survey and compares the pros and cons of recycled P fertilizers in the overall conclusions.
She refers to a recent study in Germany which found that 40 % of the organically managed fields are low in P, indicating a need for P replenishment. Bünemann also explains the actual state of P management in organic farming.
