Feeding biology, supporting roots, unlocking early nutrient efficiency.
Applied at planting, in-furrow biology goes exactly where roots explore first. This window establishes microbial populations, supports root function, and improves nutrient availability in the rhizosphere—before the crop ever shows above ground.
2025 Field Trial · Findlay, OH · RhizeBio Roots-to-Shoots Analysis
Independent metagenomic sequencing, Haney soil chemistry, and plant tissue analysis tracked the AgriBio in-furrow program from V2 through V8 on commercial corn.
Extracted from premium vermicompost, BioMax E delivers over 400 species of beneficial microorganisms directly into the root zone. It rapidly populates the rhizosphere with living biology, supports nutrient retention, and improves soil structure from the moment it's applied.
Why we use it
A two-part formula that addresses both sides of the microbial equation. DualStart® B delivers a concentrated blend of microbial-supporting carbon sources, minerals, and plant-derived compounds that stimulate soil bacteria. DualStart® F nourishes fungi with a blend of kelp extracts and humic substances. Together, they create functional balance in the rhizosphere.
Why we use it
Two different products, one spot in the program—chosen based on the goal. Both deliver ocean-derived carbon and biology into the root zone during the most critical window of crop establishment.
Why chitin matters
Chitin is a structural polysaccharide found in fungal cell walls and insect exoskeletons. Applied in-furrow, it stimulates populations of chitin-degrading bacteria—primarily actinomycetes and Bacillus species—that are also among the most effective natural suppressors of soil-borne fungal pathogens. The result: a more biologically competitive root zone from day one, without adding a fungicide.
A low-heat squid hydrolysate delivering chitin, amino acids, fats, and a balanced 2-2-2 NPK that activates chitin-degrading biology in the root zone. OMRI certified and usable from germination through harvest.
Why we use it
Plant-available phosphorus paired with carbon-based energy to fuel early root metabolism and microbial activity simultaneously. Bridges the gap between nutrient supply and biological demand in cold or tight soils.
Why we use it
Each product plays a distinct role—combined, they create a biologically active, nutrient-efficient root environment from day one.
DualStart® B + F establish and support both populations—bacteria and fungi working in concert to drive nutrient cycles and soil structure.
BioMax® E rapidly increases microbial activity and species diversity, amplifying the biological foundation laid by DualStart®.
Squid Juice floods the root zone with chitin, activating disease-suppressing bacteria and fueling the system with amino acids and carbon. SeaPhos takes the same role where P availability is the limiting factor—carbon energy paired with plant-available phosphorus.
Together, they deliver a biologically active, nutrient-efficient root environment before the crop even shows above ground.
Applied in-furrow at planting, directly alongside the seed in the root zone—extending the biological activity of seed treatment into the soil where roots will explore during early growth.
Key Takeaway
The in-furrow window doesn't get a second chance. What you put in that furrow determines what the crop has to work with for the rest of the season.
