Frequently asked questions

Is an Ulva biostimulant a fertiliser?
No. Regulation (EU) 2019/1009 places them in different functional categories: a fertiliser supplies nutrients, while a biostimulant acts on the plant's processes or on the rhizosphere, regardless of its nutrient content.
How is it applied?
Foliar or through fertigation, depending on the stage of the cycle. The label dosage per crop is published in full on the documentation page, with the frequency for each case.
Is it certified for organic farming?
The extract holds CAAE certification, the Andalusian organic farming committee. Ask us for the current certificate for the batch you are being offered.
Can I sell it under my own brand?
Yes. Own-brand supply is one of the usual routes with distributors: we supply the extract and you put it in your own packaging. Terms are agreed by volume.
Why do you not publish yield increases?
Because a performance claim needs a trial behind it, demonstrated in line with EN 17700-1:2024. Until we have one published, we do not put a percentage on this site.
