Application and dosing
The basic rule for field crops: 0.2–0.6 litres of ProtoHumiX® per 1 hectare, dissolved in 200–300 litres of water (0.1–0.2% concentration). The governing quantity here is the concentration, and the per-hectare dose is derived from it — which is why crops requiring more working fluid (orchards, vineyards) end up with a higher per-hectare dose at the very same concentration. Where the solution concentration is decisive (seed dressings, microgreens, fertigation, soil applications) — values are given in the second table.
Foliar application — dose per hectare
Field crops
| Crop | Working concentration | Dose per 1 ha (derived) | Application timing |
|---|---|---|---|
| Cereals, maize, rapeseed, soybean, sunflower | 0.1–0.2% | 0.2–0.6 l/ha in 200–300 l of water | 2–4 treatments: 3–5 leaves stage → before flowering / earing |
Vegetable crops
| Crop | Working concentration | Dose per 1 ha (derived) | Application timing |
|---|---|---|---|
| Tomato, cucumber, cabbage, pepper, zucchini, pumpkin, eggplant, onion, garlic, watermelon and melon | 0.1–0.2% | 0.2–0.6 l/ha in 200–300 l of water | Before transplanting (plants 10–12 cm) → 4–6 leaves stage → budding → 14–15 days after flowering → fruit development |
| Carrot and beetroot | 0.1–0.2% | 0.2–0.6 l/ha in 200–300 l of water | Start of vegetative growth → repeat every 25–30 days |
| Potato | 0.1–0.2% | 0.2–0.6 l/ha in 200–300 l of water (+ tuber dressing — table below) | 5–7 leaves stage → budding → repeat every 25–30 days |
Vineyards and orchards
| Crop | Working concentration | Dose per 1 ha (derived) | Application timing |
|---|---|---|---|
| Grapevine | 0.1–0.2% | 0.5–2.0 l/ha in 500–1000 l of water | Bud break → after flowering → berry growth and filling stage |
| Fruit and nut trees | 0.1–0.2% | 0.5–2.0 l/ha in 500–1000 l of water | Bud break → after flowering → fruit growth and filling stage |
| Oil trees | 0.1–0.2% | 0.5–2.0 l/ha in 500–1000 l of water | Bud break → after flowering → fruit growth and filling stage |
Perennial crops
| Crop | Working concentration | Dose per 1 ha (derived) | Application timing |
|---|---|---|---|
| Perennial crops | 0.1–0.2% | 0.5–2.0 l/ha in 500–1000 l of water | Before flowering → 3–4 applications at 10–14 day intervals |
The governing quantity is the solution concentration: 0.1–0.2% regardless of crop group. The per-hectare dose follows from it and from the working fluid volume — standard 200–300 l of water/ha, in orchards and vineyards 500–1000 l/ha. Changing the water volume? Keep the concentration, not the per-hectare dose.
Applications requiring a specific concentration
| Application | Concentration / dose | Notes |
|---|---|---|
| Seed dressing | 0.3 l / 1000 kg of seeds | Soak for 5–6 hours or mechanical dressing |
| Tuber dressing (potato) | 300–400 ml / 1000 kg of tubers | Before planting |
| Seed dressing (hemp, flax, tobacco) | 90–100 ml / 100 kg of seeds | Plus foliar spray 0.2–0.6 l/ha at 3–4 leaves stage |
| Microgreens | 1–2 l / 1000 l of water (0.1–0.2%) | Spray seeds and sprouts, repeat every 48 hours |
| Fertigation (root zone) | 3.3 l / 1000 l of water (0.33%) | 1–2 times a month |
| Soil application (between harvest and sowing) | 6.7 l / 1000 l of water (0.67%) | Once a month |
| Soil drench — vineyards, orchards | 3.3 l / 1000 l of water | Directly to the root zone |
| Soil drench — oil trees | 3.3–4.0 l / 1000 l of water | Directly to the root zone |
No per-hectare dose is given here, because the water volume follows from the technology (seed treater, drip system, tank), not from the field area. For soil application what counts is the amount of product delivered per hectare — calculate it as the concentration times the volume of solution actually applied on that hectare.
The product can be mixed with many plant protection products — the user is responsible for testing the mixture before use. Add ProtoHumiX® to the tank last.
Storage and shelf life
- Range in which the product retains its properties: -20°C to +40°C. Recommended storage: 0–30°C, in the original, tightly closed packaging, away from direct sunlight. The product freezes below 0°C — after thawing and mixing it retains its usable properties.
- Shelf life: 36 months from the production date. Batch number and production date are on the packaging.
Frequently asked questions
How long does delivery take?
Orders in stock usually ship within 1–2 business days. Courier delivery in Poland takes a further 1–2 business days.
How should I store ProtoHumiX®?
Keep the product in a tightly closed container, above freezing, away from direct sunlight. See the "Storage" section below for details.
Can I order more than 200 units?
Yes — orders above 200 pcs and IBC 1000 l containers are priced individually. Contact us via the form and tell us the quantity you need.
Does the product have the certificates required in the EU?
Yes. Both products carry a CE certificate under EU Regulation 2019/1009 (biostimulant PFC 6(B) / soil improver PFC 3(B)). See the full list on the "Certificates" page.
What's the difference between PFC 6(B) and PFC 3(B)?
PFC 6(B) is a foliar biostimulant applied to plants — it improves nutrient uptake and stress resistance. PFC 3(B) is a soil improver applied to the soil — it permanently improves soil structure and water retention.
