Table 5. Typical Composition of Manures and Other Organic Fertilizer Sources.
Manures vary greatly in their nutrient content according to the kind of feed used, the percentage and type of litter or bedding, the moisture content, and the age and degree of rotting or drying.. The following data are representative analyses from several reports.

§ 205.600 Evaluation criteria for allowed and prohibited substances, methods, and ingredients.
(6) The substance is essential for the handling of organically produced agricultural products.
(2) Chlorine materials – Except, That, residual chlorine levels in the water shall not exceed the maximum residual disinfectant limit under the Safe Drinking Water Act.
(5) Oils, horticultural – narrow range oils as dormant, suffocating, and summer oils.
(1) Coppers, fixed – copper hydroxide, copper oxide, copper oxychloride, includes products exempted from EPA tolerance, Provided, That, copper-based materials must be used in a manner that minimizes accumulation in the soil and shall not be used as herbicides.
(2) Copper sulfate – Substance must be used in a manner that minimizes accumulation of copper in the soil.
(3) Hydrated lime – must be used in a manner that minimizes copper accumulation in the soil.
(6) Oils, horticultural, narrow range oils as dormant, suffocating, and summer oils.
(1) Aquatic plant extracts (other than hydrolyzed) – Extraction process is limited to the use of potassium hydroxide or sodium hydroxide; solvent amount used is limited to that amount necessary for extraction.
(6) Micronutrients – not to be used as a defoliant, herbicide, or desiccant. Those made from nitrates or chlorides are not allowed. Soil deficiency must be documented by testing.
§ 205.602 Nonsynthetic substances prohibited for use in organic crop production.
(g) Potassium chloride – unless derived from a mined source and applied in a manner that minimizes chloride accumulation in the soil.
(h) Sodium nitrate – unless use is restricted to no more than 20% of the crop’s total nitrogen requirement.
Ivermectin – prohibited in slaughter stock, allowed in emergency treatment for dairy and breeder stock when organic system plan-approved preventive management does not prevent infestation. Milk or milk products from a treated animal cannot be labeled as provided for in subpart D of this part for 90 days following treatment. In breeder stock, treatment cannot occur during the last third of gestation if the progeny will be sold as organic and must not be used during the lactation period of breeding stock.
(13) Phosphoric acid – allowed as an equipment cleaner, Provided, That, no direct contact with organically managed livestock or land occurs.
(3) Lime, hydrated – (bordeaux mixes), not permitted to cauterize physical alterations or deodorize animal wastes.
(e) As synthetic inert ingredients as classified by the Environmental Protection Agency (EPA), for use with nonsynthetic substances or a synthetic substances listed in this section and used as an active pesticide ingredient in accordance with any limitations on the use of such substances.
EPA List 4 – Inerts of Minimal Concern.
§ 205.604 Nonsynthetic substances prohibited for use in organic livestock production.
(9) Flavors, nonsynthetic sources only and must not be produced using synthetic solvents and carrier systems or any artificial preservative.
(v) Smoked – nonsynthetic smoke flavoring process must be documented.
(9) Chlorine materials – disinfecting and sanitizing food contact surfaces, Except, That, residual chlorine levels in the water shall not exceed the maximum residual disinfectant limit under the Safe Drinking Water Act.
(34) Sulfur dioxide – for use only in wine labeled “made with organic grapes,” Provided, That, total sulfite concentration does not exceed 100 ppm.
§ 205.606 Nonorganically produced agricultural products allowed as ingredients in or on processed products labeled as organic or made with organic ingredients.
The following nonorganically produced agricultural products may be used as ingredients in or on processed products labeled as “organic” or “made with organic (specified ingredients or food group(s))” only in accordance with any restrictions specified in this section.
Any nonorganically produced agricultural product may be used in accordance with the restrictions specified in this section and when the product is not commercially available in organic form.
§ 205.607 Amending the National List.
(b) A person petitioning for amendment of the National List should request a copy of the petition procedures from the USDA at the address in § 205.607(c).
