Uriini on võimalik kääritamise teel väärindada (upcycle) tõhusaks biostimulaatoriks. (vt. nt. Toopi)Erinevalt tüüpilistest mineraalväetistest, mis rikastavad mulda, aitab uriinist toodetud stimulaator taimedel mullast mineraaltoitaineid paremini kätte saada.
Nii väheneb taimede poolt kasutamata mineraalväetiste negatiivne mõju põhjaveele ning farmer saab kasutada vähem väetisi. Samuti väheneb koormus reoveesüsteemile ja veekeskkonnale kui kogume uriini eraldi kokku.
Muud Keskkonna kasutegurid:
- Puhta vee raiskamise vähendamine
- Vähem hormoone ja patogeene vees
- Tõkestame eutrofeerumist
- Kõrge väetise hinnaga võitlemine
- Ei raiska head kraami
- Põhjavee hoidmine
Mis oleks, kui saaksid taskukohase hinnaga seda biostimulaatorit ise kodus toota?
FAQ
Is it safe?
Safety is the top priority for such a product. Fermentation largely ensures safety. To remove pathogens or pharmaceutical residues that do not break down during fermentation, we use appropriate filters. To ensure safety, laboratory tests are also conducted on the final product.
Does our biostimulant affect the taste of the crops?
No! Even the typical smell of urine disappears during fermentation as well.
How to collect?
The easiest way to start is by collecting from urinals and dry toilets. However, various simple and elegant solutions have already been devised and used. In short, to protect nature, no one has to urinate into a bottle.
Why not just use urine directly?
Of course, you can simply use urine if you dilute it with water first; otherwise, the urine will burn the plants. It is a good fertilizer, but you would need an excessive amount of urine to replace other fertilizers. If you were to collect all the urine produced in Estonia annually, it would only replace 6% of the annual nitrogen content of mineral fertilizers.
How much urine is needed for biostimulant production using the PissIn method?
To stimulate an average Estonian farm (91 hectares), you would need the annual urine output of just five people. Typically 20-25 liters per hectare.
