Down to Earth Soluble Root Zone | 4oz - OMRI Listed - (Case of 12)

OMRI Listed Soluble Mycorrhizal Fungi and Trichoderma Blend for Root Growth (4oz)

Down to Earth Soluble Root Zone is an OMRI Listed professional-grade inoculant containing a powerful blend of beneficial soil organisms that colonize plant roots and expand into the surrounding soil to greatly increase the absorptive surface area of root systems. It includes mycorrhizal fungi, Trichoderma, and a diverse mix of bacterial species that work symbiotically to promote enhanced activity in the rhizosphere, improved soil structure, and extensive root growth.

The 4oz size (Case of 12) is convenient for nurseries, propagators, and home gardeners who want a supply of Soluble Root Zone for transplanting, propagation, or applying at planting throughout the season. The soluble formula can be mixed into water for drench or irrigation application.

Key Features & Benefits

• Mycorrhizal Fungi — Colonize plant roots and form an extended network in surrounding soil, greatly increasing the absorptive surface area of root systems.
• Trichoderma — Beneficial fungal organisms that support root health and rhizosphere activity.
• Diverse Beneficial Bacteria — A diverse mix of bacterial species working symbiotically with fungi to enhance soil structure and root zone biology.
• OMRI Listed — Approved for certified organic production.
• Soluble Formula — Water-soluble formula for application as a soil drench or through irrigation systems.

Who Should Use Down to Earth Soluble Root Zone

Soluble Root Zone suits nursery growers, propagators, home gardeners, and market farmers who want to establish beneficial root zone biology at transplanting or planting. The soluble formula is particularly practical for those who apply inoculant through irrigation, as a soil drench, or in seedling and transplant programs where direct root contact with the inoculant is needed.

Mycorrhizal Fungi and the Root Zone

Mycorrhizal fungi form symbiotic relationships with plant roots, extending hyphae far beyond the root surface into surrounding soil. This network effectively increases the absorptive surface area of root systems, enabling plants to access water and nutrients from a much larger soil volume than roots alone can reach. Trichoderma species and diverse beneficial bacteria complement mycorrhizal activity by supporting rhizosphere health and soil structure. Together, these organisms help create an active, biologically rich root zone that supports plant establishment and growth.

Frequently Asked Questions

What organisms are in Soluble Root Zone?

It contains mycorrhizal fungi, Trichoderma, and a diverse mix of beneficial bacterial species that work symbiotically to colonize plant roots and enhance activity in the rhizosphere and surrounding soil.

Is Down to Earth Soluble Root Zone OMRI Listed?

Yes. It is OMRI Listed and appropriate for certified organic production.

How is Soluble Root Zone applied?

The soluble formula can be mixed into water and applied as a soil drench or through irrigation systems, or applied directly into the planting hole at transplanting. Follow current label directions for rates and application timing.

How does Soluble Root Zone differ from Granular Root Zone?

Soluble Root Zone is a water-soluble formula that can be mixed into water for drench or irrigation application — suited for situations where liquid application is preferred. Granular Root Zone is a dry granular product applied to soil at planting. Both contain mycorrhizal fungi, Trichoderma, and beneficial bacteria.

Can Soluble Root Zone be used at transplanting?

Yes. It is well suited for use at transplanting, where it can be applied as a soil drench around root zones to establish beneficial colonization from the earliest stage of plant establishment.
