Summary

It is prohibited to fertilize the soil with fresh blood, guano, Chilean nitrate, urea, or slaked lime or quicklime. Soil Association Organic Standards. Paragraphs 4.8.12.

Difference

Soil Association standards have further restrictions than EU Regulation 2092/91, where for example guano is permitted as fertiliser where the need is recognised by the inspection body. It is prohibited by the Soil Association standards.

Justification

Guano extraction is unsustainable on a large scale because of habitat damage and limited reserves. Historically, guano was used as a major nitrate source, but nitrogen fixed from the atmosphere should be the main source of nitrate in organic farming.
