Soybean
Nitrogen-fixing symbiosis and prevention of Sclerotinia in a natural way
Application conditions: Soil pH 6–7.5, organic matter min. 1.5%. Calm weather, moist soil, 5–25 °C.
Soil treatment
Microbiological soil inoculation and organic-matter supply
| # | Recommended timing | Product | Dose | Water |
|---|---|---|---|---|
| A | On the previous crop's stubble | Natur Forte or Natur Micro T | Forte: 3 L/ha + 1 L/ha fungus · Micro T: 3 L/ha + 1.5 L/ha fungus | 50–300 |
| B | 2–3 weeks before sowing, with tillage | Natur Forte or Natur Nova | Forte: 3 L/ha + 1 L/ha fungus · Nova: 4 L/ha + 1 L/ha fungus | 50–300 |
| C | In one pass with sowing | Natur Forte or Natur Nova | Forte: 3 L/ha + 1 L/ha fungus · Nova: 4 L/ha + 1 L/ha fungus | 30–80 |
The bacterial and fungal components must be mixed together before application. Trichoderma harzianum acts as a biocontrol agent to prevent Sclerotinia and other soil-borne pathogens. For soybean, Natur Rhizo (Bradyrhizobium + Rhizobium) is recommended at seed treatment for symbiotic nitrogen fixation — please ask our advisors for a recommendation.
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. | First branching, together with herbicide | Natur Plasma T + Natur Active + MONO Mg, Ca, Mo (or Natur Power + MONO) | Plasma T + Active: 2 + 4 + 1+1+1 · Power: 2–3 + 1+1+1 L/ha | 15–300 |
| 2. | At the onset of budding | Natur Plasma T + Natur Active + MONO S concentrated, B concentrated (or Natur Power + MONO) | Plasma T + Active: 2 + 4 + 0.5+0.5 · Power: 2–3 + 0.5+0.5 L/ha | 15–300 |
| 3. | At pod formation | Natur Plasma T + Natur Active + MONO S concentrated, B concentrated, K (or Natur Power + MONO) | Plasma T + Active: 2 + 4 + 0.5+0.5+1 · Power: 2–3 + 0.5+0.5+1 L/ha | 15–300 |
Drone application: the specified product dose can be applied with 10 L/ha of water. At least 10–14 days between two treatments. Soybean is a previous crop with green-manure value — after the Rhizo treatment, the nitrogen reserve remaining in the soil also benefits the following crop.
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.
