What Oregon requires before soil amendments, plant amendments, inoculants, biostimulants and similar products are sold there, field by field, with the source for each. Checked on October 4, 2026.
Whether a product is a fertilizer, soil amendment, plant amendment or beneficial substance depends on what its label claims, and each state decides; the same product can fall in different categories in different states. This site lists what each state's law and agency say. It does not say which category any product is in.
Fees, forms and rules change: confirm with the state agency before you register or sell.
