Broadacre nutrition & legume support
Six microbial species plus Metabolites, formulated for broadacre crops, soils with NPK lockup and complementary legume Rhizobium support.
Calculated contributions per mL of finished blend. Not measured viable counts after blending or storage.
Get to know the biology inside each blend. Select a species to explore its role, and switch units to see its calculated CFU contribution.
Conceptual illustration. Organisms are enlarged and not to scale.
Root association. Nutrient cycling. Plant signalling. Explore how each species contributes to the biological approach.
CFU means colony-forming units. Counts are calculated from website label concentrations and the supplied recipes; all strains and inputs belonging to the same species are combined. They are formulation input equivalents, not measured viable counts after blending or storage. Confirm the supplied lot specification before batching: historic label and package species listings differ.
Roles describe biological functions associated with each species, not a proven response from these finished blends. Establishment and crop response depend on strain, soil, moisture and management.

Soil microbiologist · Embrapa
Recognised for advances in biological nitrogen fixation and crop nutrition, Dr Hungria’s work has helped bring microbial research into agricultural practice.
Read about her awardStrain BR4 contributes to BioFOR’s broadacre nutrition and complementary legume Rhizobium-support focus.
The connection is the bacterial species: Azospirillum brasilense. International research explores its role in crop-root interactions and nutrient uptake. BioFOR contains strain BR4 of this species.
Published Brazilian studies used other strains, including Ab-V5 and Ab-V6. They support the wider scientific context, but do not establish equivalent performance for BR4 or the BioFOR blend. Dr Hungria’s award is not an endorsement of Wilchem products.
Hungria and colleagues evaluated selected strains at two Brazilian locations over multiple seasons. Yield responses occurred under the study’s low starter-nitrogen conditions. The authors attributed responses to increased uptake of several nutrients, rather than specifically to nitrogen fixation.
Read the original study ↗A meta-analysis examined inoculation with Ab-V5 and Ab-V6 across 103 field trials at 54 Brazilian sites. It provides broader evidence for those strains and illustrates why the strain, crop and growing conditions matter when interpreting results.
Explore the meta-analysis ↗Glenalan Farm, Wanamal • Wheat Zen • 2024 demonstration. Explore reported soil and microbial community observations.
GA1 used the baseline fertiliser program. GA3 added a wider systems treatment, including mineral nutrition, humate and biological inputs.
The document reports differences in soil nutrient availability and microbial community profiles. Because several inputs changed, this demonstration cannot isolate the effect of microbes alone.
The supplied report does not provide replication or statistical uncertainty for these displayed observations. Microbial counts are document-reported ARISA observations, not CFU or proof of a beneficial outcome. These treatments are not the new BioFOR or BioBAC blends.

BioFOR combines Trichoderma harzianum and T. asperellum with four bacterial species and Metabolites. Its broadacre focus connects root development with nutrient access.
For legumes, Azospirillum brasilense provides the basis for complementary rhizosphere support. Continue crop-specific Rhizobium inoculation and assess nodulation; BioFOR does not replace the legume’s appropriate Rhizobium inoculant.
Azospirillum brasilense, Bacillus megaterium and B. mucilaginosus contribute biological roles associated with nitrogen fixation and phosphorus and potassium mobilisation. BioFOR is positioned for soils with NPK lockup, alongside soil testing, crop removal budgets and balanced nutrition.
Microbial activity does not create phosphorus or potassium. Access to soil reserves depends on mineralogy, moisture, pH, root activity and establishment of the organisms.
BioBAC combines two Trichoderma species with six bacterial species and Metabolites. Its intended focus is horticultural crops, high disease pressure soils and stubble pressure.
The components contribute distinct biological functions. Performance of the finished blend needs its own validation; retain crop protection, residue management and diagnosis within the wider crop program.
Both blends are made to order in 1,000 L IBCs and used within one month of batching. The displayed species CFU figures are calculated formulation inputs; they do not certify viable counts after blending or storage.
International studies inform biological mechanisms. The WA demonstration offers local observations, but several inputs changed together. Neither evidence source alone establishes the response of these new blends.

Derived from available component evidence. Avoid: an adverse flag is present. Caution: a caution flag is present. No flagged conflict*: no adverse flag in the available data, but confirmation is required. Some constituents lack specific test evidence; no result validates the finished blend.
Screening descriptions conservatively interpret the source colours; the supplied chart does not give a written colour legend. Results apply to the exact listed formulation and test dose, not all products sharing an active ingredient. Refer to current chemical labels.
