There are no “biostimulants” as such in the Spanish legislation. However, they can be placed on the market as so-called “other fertilizers and special fertilizers” (“otros abonos y productos especiales”) of group 4 of Royal Decree 506/2013.

These “other products” are defined in Article 14 as products that provide an other kind of fertilizer, either to soil or to the plant, substances that promote and regulate the absorption of nutrients or that correct physiological anomalies.
