Soil fertility is a particular issue in organic/low input protected cropping systems because of the need for high crop offtakes to justify the infrastructure costs. The use of animal by-products (e.g. blood, hoof/horn meal) is common but this raises ethical issues. Legumes in various forms can offer an alternative:
We would work closely with commercial growers (e.g. in the Organic Growers Alliance) who are already using these approaches or who have particular existing issues to identify and to overcome some of the barriers that prevent legumes being used to build fertility in protected cropping situations.
