Application conditions: Soil pH 6–7.5, organic matter min. 1.5%. Soil temperature ≥ 8 °C.
Soil treatment
Microbiological soil inoculation and organic-matter supply
| # | Recommended timing | Product | Dose | Water |
|---|---|---|---|---|
| A | Before planting, broadcast over the whole surface | Natur Fertil | 2 t/ha 20 kg / 100 m² | — |
| B | In one pass with planting | Natur Fertil | 1.4 t/ha 14 kg / 100 m² | — |
| C | 1–3 weeks before planting, with tillage | Natur Nova | 4 L/ha bacteria + 1 L/ha fungus | 250–300 |
| D | In one pass with planting | Natur Nova | 4 L/ha bacteria + 1 L/ha fungus | 250–300 |
Mix the bacteria and fungus components before application. A total of 5.5 L/ha is to be applied.
Application method
Apply the soil treatment as a water-diluted solution by spraying, then incorporate it into the topsoil. It can be applied together with herbicide and liquid N fertilizer.
Foliar fertilizer / Crop treatment
Biostimulant and foliar treatments by season
| # | Recommended timing | Foliar fertilizer | Dose | Water |
|---|---|---|---|---|
| 1. | In a stand of 20–30 cm growth | Natur Plasma T + Natur Active + MONO K, Mg, Zn | 2 + 5 + 1+1+1 L/ha | 200–300 |
| 2. | During the tuber formation stage | Natur Power + MONO K, Mg, Mn | 3 + 1+1+1 L/ha | 200–300 |
| 3. | At flowering | Natur PlasMAX + MONO K, B | 1 + 1+1 L/ha | 200–300 |
At flowering MONO Boron and at tuber formation MONO Magnesium are recommended to improve quantity, quality and storability.
Application conditions
Weather suitable for spraying (below 25 °C, calm conditions). In summer heat, spray in the morning or evening hours. Tank-mixable with plant-protection products — always add the foliar fertilizer last. Allow at least 10–14 days between two treatments.
