Bio-Fume Brassica Mix
Bio-Fume Brassica Mix combines daikon radish, yellow mustard, white mustard, oriental mustard and canola in a five-species brassica blend. The mix is designed to provide rapid seasonal growth, nutrient capture, soil cover, diverse root architecture and the potential to be managed as a biofumigation cover crop.
Mix Components
Five brassica species combine different growth habits and rooting characteristics within one cover crop planting.
More Than a Single-Species Brassica
The five-species formulation combines different brassica growth and rooting characteristics while maintaining the nutrient-scavenging function associated with brassica cover crops.
Nutrient Scavenging
Brassicas can take up residual soil nitrogen and other available nutrients while actively growing, temporarily retaining those nutrients within plant biomass during the cover crop period.
Rapid Biomass
Mustards, radish and canola are capable of producing substantial vegetative growth when planted into favorable conditions. Strong biomass production is particularly important when the crop will be managed for biofumigation.
Rooting Diversity
Daikon radish contributes a pronounced taproot while the mustards and canola contribute additional branched root systems, creating more rooting diversity than a single brassica species alone.
Living Soil Cover
An actively growing brassica stand keeps the soil covered during an otherwise fallow period and can help protect the soil surface from erosion.
Residue & Nutrient Cycling
Following termination, brassica plant material decomposes relatively quickly, returning captured nutrients and plant residue to the soil system.
Biofumigation Potential
Mustards and other brassicas contain glucosinolates that can form biologically active compounds when plant tissue is thoroughly disrupted. The actual effect depends heavily on species, biomass and termination management.
Agronomic Note: Biofumigation is a management process, not simply a result of planting brassicas. Results vary with species, biomass, growth stage, soil conditions, target organism and how the crop is terminated.
Management Determines the Biofumigation Effect
Brassica tissues contain glucosinolates. When plant cells are broken, these compounds can be converted into biologically active products such as isothiocyanates. Maximizing this process requires more than simply growing a brassica cover crop.
Important: Biofumigation should not be treated as a guaranteed pesticide or disease-control outcome. Research results vary by brassica species, target pest or pathogen, soil environment and termination method. Use Bio-Fume Brassica Mix as part of an integrated crop-management program.
