Citric Acid – nonsynthetic
Allowed
Crop Management Tools and Production Aids
Nonsynthetic
Citric Acid – synthetic
Allowed with Restrictions
Crop Fertilizers and Soil Amendments, Crop Management Tools and Production Aids
Synthetic
When used in crop fertilizers or soil amendments, may only be used to pH adjust liquid fish products. The amount of acid used shall not exceed the minimum needed to lower the pH to 3.5. See also FISH PRODUCTS, LIQUID – STABILIZED. When used for equipment cleaning, considered to meet requirements under 205.105 provided there is no crop or soil contact. Must be rinsed before equipment contact with crops or soil. See also EQUIPMENT CLEANERS FOR FARMS.
Drip Irrigation Cleaners
Allowed
Crop Management Tools and Production Aids
Nonsynthetic
Allowed nonsynthetic drip irrigation cleaners include acetic acid, vinegar, citric acid, and other naturally occurring acids.
205.105
Fish Products, Liquid – stabilized
Allowed
Crop Fertilizers and Soil Amendments
Synthetic
Liquid fish products can be pH adjusted using synthetic citric, sulfuric, or phosphoric acid. The amount of acid used cannot exceed the minimum amount needed to lower the pH to 3.5. May be stabilized with preservatives that are on the National List and are allowed for that use or are nonsynthetic. See also FISH PRODUCTS, MULTI-INGREDIENT.
205.601(j)(7) Liquid fish products—can be pH adjusted with sulfuric, citric or phosphoric acid. The amount of acid used shall not exceed the minimum needed to lower the pH to 3.5.
Fish Products, Multi-ingredient
Allowed
Crop Fertilizers and Soil Amendments
Synthetic/Nonsynthetic
Liquid fish products stabilized with synthetic citric, phosphoric, or sulfuric acid that are blended with other materials must have a final pH of no less than 3.5 measured prior to being formulated with other ingredients permitted in organic production for use as fertilizers and soil amendments. Synthetic ingredients cannot be used to fortify nitrogen, phosphate, or potash levels. Liquid fish products can be pH adjusted using citric, sulfuric, or phosphoric acid.
205.601(j)(7) Liquid fish products—can be pH adjusted with sulfuric, citric or phosphoric acid. The amount of acid used shall not exceed the minimum needed to lower the pH to 3.5.
