Canadian Organic Standards change for Hydrolyzed Proteins and Amino Acids
Hydrolyzed protein-based fertilizers have had one of the biggest changes on the Permitted Substances List from the 2020 to the 2026 version. The 2020 version had them reviewed to amino acids, which was the following annotation:
| Table 4.2 ─ Substances for crop production | |||
|---|---|---|---|
| Substance name(s) | Origin and usage |
Column 1 Soil amendments
|
Column 2 Production aids |
| Amino acids | Derived from plants, animals or microorganisms, and extracted, hydrolyzed or isolated by non-chemical means, such as physical separation, or by substances listed in Table 4.2 (Column 1 or Column 2) excluding Formulants used in crop production aids. | ✓ | ✓ |
Now, amino acids have been removed from Table 4.2 and replaced with Hydrolyzed proteins of plant origin and Hydrolyzed proteins of animal origin. The annotation for both are the following:
| Table 4.2 ─ Substances for crop production | |||
|---|---|---|---|
| Substance name(s) | Origin and usage |
Column 1 Soil amendments |
Column 2 Production aids |
| Hydrolyzed proteins of plant origin |
Resulting from enzymatic hydrolysis (in conjunction with physical processes). Shall not contain more than 0.3% hydroxyproline (as a percentage of total amino acids). Shall not contain more than 15% N (dry basis). At least 90% of the total nitrogen shall be organic (protein) nitrogen. Isolated amino acids such as glycine, lysine and methionine are prohibited. Nitrogen compounds may not be added during hydrolysis |

| Hydrolyzed proteins of animal origin |
Resulting from enzymatic hydrolysis (in conjunction with physical processes). Shall not be applied to the edible portion of crops. Shall not contain more than 17% N (dry basis). At least 90% of the total nitrogen shall be organic (protein) nitrogen. Isolated amino acids such as glycine, lysine and methionine are prohibited. Nitrogen compounds may not be added during hydrolysis. |

If a product no longer meets Canadian Organic eligibility standards subsequent to the updated annotations, the following are top reasons why:
- Needs to be reviewed to the new annotation
- Contains an isolated amino acid
- Nitrogen level exceeds 15%
- Hydroxyproline level exceeds 0.3%
