| Clay (e.g. bentonite, perlite, zeolite) | Not chemically treated |
| Vermicculture | - |
| Peat (prohibited for soil conditioning) | Excluding synthetic additives permitted for inclusion in potting mixes. Use limited to horticulture (market gardening, floriculture, arboriculture, nursery). Prohibited for soil conditioning Not chemically treated |
| Humus from earthworms and insects | - |
| Zeolites | - |
| Wood charcoal | - |
| Chloride of lime | Foliar treatment of apple trees, after identification of deficit of calcium. Need recognized by the TPA. |
| By-products of industries processing ingredients from organic agriculture | Can only be used after TPA approval and shown to have no adverse affect on the soil |
Factory Farming refers to industrial management systems that are heavily reliant on veterinary and feed inputs not permitted in organic farming.
Note: Chilean nitrate and nitrogenous fertilisers including urea are prohibited.
