Alternative fertilizers from nutrient-rich wastes for organic crops
- A main challenge in optimizing organic crop production is the need to acquire alternative source of nutrients to satisfy the growing demand, and to reduce the conventional manure importation.
- In parallel, the production of organic wastes with high content of organic matter and nutrient is increasing worldwide. Therefore, their use in agriculture can potentially contribute to close the nutrient cycles. Our aim was to investigate how the combination of different wastes sources for more optimal NPKS ratios affects their fertiliser value.
