Fermented nettle extract
Biofertilizers Bio-inputTraditionally used in organic farming for routine plant care, it provides rapidly available nitrogen when used in diluted form as a foliar or irrigation fertilizer.
Application description: Dilute before applying: approximately 1:10 for foliar spraying as part of your plant's regular care routine, or 1:20 for use as a foliar or irrigation fertilizer. Apply preferably in the morning or at dusk. Repeat every 10–15 days.
Freshly strained manure can be stored for a few months in a cool place away from light, in a tightly sealed container (it has a strong odor). To use as a foliar fertilizer or for irrigation, dilute it to 10 percent (1 liter of liquid manure per 10 liters of water). For spraying on foliage, use a more diluted solution: approximately 1.5 liters of liquid manure per 100 liters of water. Avoid applying it undiluted, as it can burn the plants.
1) Cut the fresh stinging nettles before they bloom and chop them coarsely. 2) Submerge all the nettles in 10 liters of water in a non-metallic container. 3) Stir well to ensure they are completely submerged. 4) Cover the container without sealing it tightly, allowing the fermentation gases to escape. 5) Stir the mixture every 2 days. 6) Let it ferment for about 10 days, until it stops bubbling and gives off a strong, characteristic odor. 7) Strain the liquid and discard the plant matter (you can compost it).
A dark brown liquid with a strong odor, rich in nitrogen and minerals, used in diluted form as a foliar or irrigation fertilizer and, when diluted even further, as part of routine foliage care.
