GREEN MANURE Biofumigation Seed Mix

Our Biofumigation Seed Mix is a potent blend of fast-growing brassicas specially selected to suppress soil-borne pests, pathogens, and weeds. When chopped and incorporated, these plants release natural biofumigant compounds—glucosinolates—that break down into substances with cleansing effects on soil biology. Ideal for growers seeking a natural way to improve soil health between crop cycles, particularly before planting sensitive vegetables like tomatoes, brassicas, or carrots.

  • Releases natural fumigant compounds to reduce harmful soil pathogens and nematodes.
  • Builds biomass and adds organic matter for improved soil fertility and structure.
  • Breaks weed and pest cycles to give your next crop a clean start.
  • Perfect for cool-season planting and fallow periods in rotations.
  • Recommended for organic gardeners, market growers, and permaculture systems.

What’s Inside?

A carefully balanced mix of high-performing brassicas for maximum biofumigant effect:

  • White Mustard (Sinapis alba) – Fast-growing and rich in glucosinolates
  • Radish (Raphanus sativus) – Deep taproots improve soil structure
  • Ethiopian Mustard (Brassica carinata) – High biomass and fumigant power
  • Rocket (Eruca sativa) – Adds diversity and cool-season vigour
  • Brown Mustard (Brassica juncea) – Strong fumigant effects at low inclusion rates

Plant Details:

  • Plant Type: Cool-season annual brassica mix with biofumigant properties
  • Coverage: 1 kg sows approximately 400–500 m²

Sowing Information:

  • Sow When:
    Temperate Regions: Late summer to autumn or early spring
    Subtropical Regions: Autumn to early spring
    Tropical Regions: Autumn to early spring (in cooler, drier months)
  • Germination: 5–10 days (at 10–25°C)
  • Depth: Sow 1 cm deep
  • Position: Full sun preferred
  • Sow Where: Broadcast over prepared soil and rake in lightly
  • Soil Type: Well-drained, fertile soil with moderate moisture
  • Spacing: Broadcast evenly or sow in rows 20–30 cm apart

Management:

  • Water regularly during establishment; reduce once plants are mature.
  • Chop and incorporate into soil at early flowering (around 6–8 weeks).
  • Allow 2–4 weeks for residues to decompose before planting food crops.

Harvest and Incorporation:

Cut and dig in at flowering for optimal release of glucosinolates. Wait 2–4 weeks before planting subsequent crops to allow biofumigant compounds to break down fully.

When to Sow Biofumigation Mix in Your Climate

Climate Zone Best Planting Time Tips
Temperate February–April or August–October Sow after summer crops or early spring before main crop planting.
Subtropical March–July Ideal during the cooler dry season; avoid extreme summer heat.
Tropical April–July Sow during dry season when soil is cooler and less humid.
Cool Late summer–early autumn Sow after harvesting summer vegetables; tolerates light frost.
Arid March–May Use mulch and irrigation during dry spells to establish quickly.
