Closing the Loop: Nutrient Circularity in Agricultural Systems

/in /by

Reading Time: 4 minutes

Production systems that are highly reliant on fertiliser is exposed to high risk and is severely influenced by fertiliser prices. Nutrient circularity is a concept which relates to the efficient use and recycling of nutrients in a closed-loop system. This approach can help to reduce the need for synthetic fertilisers and other inputs, increase resource use efficiency, and support sustainable agricultural and food systems.
