BIO IRON - Microbial Soil Inoculant with Iron Humate

A powerful blend of beneficial soil microorganisms to promote vigorous roots and robust plants

BIO IRON is a concentrated blend of iron humate and four species of beneficial plant-associated microbes designed to boost root health, nutrient uptake, and overall plant performance. It delivers targeted microbial and mineral support where it is needed most, whether you’re growing in soil, raised beds, or commercial media blends.

BIO IRON combines 14% plant-available iron from iron humate with Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus licheniformis, and Streptomyces nigrescens. These soil-friendly microbes colonize the rhizosphere and improve root zone biology. They support iron solubilization and organic matter breakdown, and help plants access hard-to-reach nutrients.

Why use BIO IRON?

• Enhances root growth and vigor
• Increases iron availability in the root zone
• Improves nutrient cycling and uptake
• Promotes greener, more resilient plants
• Non-phytotoxic and safe for all crops
• Dust-free and easy to apply, with no agitation or special mixing equipment required
• Compatible with most fertilizers and soil conditioners
• Suitable for organic, regenerative, and conventional systems

Crop Use

Vegetables, fruits, herbs, hemp, ornamentals, trees, shrubs, vines, greenhouse crops, turfgrass, landscape plants, nursery containers, raised beds, row crops, and much more. Use at transplant, on established crops, or as part of ongoing soil fertility management.

Directions

BIO IRON can be applied as a soil blend, top dress, broadcast, or in-furrow. Water in after every application to activate the beneficial microbes and move nutrients into the root zone. Reapply every 4–12 weeks as needed.

Soil Blending

Mix 3–7 lbs per cubic yard of potting soil, garden soil, or growing media. Use 5 lbs per yard for typical crops. Increase the rate for high-demand or problem crops; lower rates may be used for longer-cycle plants like trees and perennials.

Top Dressing

• Containers and beds: Apply ½–1 tbsp per 4" pot or 5–10 lbs per 1,000 sq ft.
• Trees and shrubs: Apply 1 oz per 1" trunk caliper.

Lightly water in to move the product into the root zone.

Turf Grass

• Problem areas: Apply 5–10 lbs per 1,000 sq ft
• General maintenance: Apply 5 lbs per 1,000 sq ft every 4–12 weeks

Agricultural Use

Apply 5–10 lbs per acre as a top dress, in-furrow, or soil incorporation. Apply as close to the plant’s root zone as possible and water in after spreading.
