Holganix’s chief technology officer, Austin Hausmann, says the company’s Bio 800 product aims to rebuild depleted soils by reintroducing beneficial microbes and restoring natural nutrient cycles. As pressure mounts on farmers and turf managers to cut chemical inputs and boost resilience, the approach highlights a broader shift toward biologically driven soil management.
How it works: rebuilding the soil’s living network
According to Hausmann, Bio 800 is positioned as a microbial soil amendment designed to change the biological balance in the root zone rather than simply supplying nutrients. The product contains a diverse mix of microbes and organic substrates intended to jump-start processes that plants rely on — from nutrient mineralization to enhanced root development.

Rather than acting like a conventional fertilizer, the product is described as promoting natural functions: microbes break down organic matter, mobilize locked-up nutrients, and form beneficial associations with plant roots. That activity can, in theory, increase the efficiency of applied fertilizers and improve plant access to water and nutrients.
Why this matters now
Growers and turf managers are facing several converging pressures: rising input costs, regulatory scrutiny around runoff and nutrient management, and a greater focus on resilience to drought and heat. Biological soil products such as Bio 800 respond directly to those concerns by attempting to improve the living component of soil — the part that conventional chemistry doesn’t address.
For stakeholders, the practical implications are straightforward: if soil biology can be restored, managers may rely less on synthetic inputs, achieve steadier plant growth under stress, and build longer-term soil health. That can translate into cost savings, reduced environmental risk, and improved productivity — though outcomes can vary by site and management practices.
Reported benefits — and the limits
Holganix highlights several potential advantages when Bio 800 is used as part of an integrated program. Independent verification of results can differ between environments, and the company notes that biological products tend to perform best when paired with good cultural practices.
- Improved nutrient cycling — microbes can make existing soil nutrients more available to plants.
- Enhanced root development — users often report deeper, denser root systems that help with drought tolerance.
- Reduced reliance on synthetic inputs — by increasing nutrient use efficiency, biologicals may allow for lower fertilizer rates.
- Support for soil structure — biological activity can contribute to aggregation, improving water infiltration and aeration.
What scientists and practitioners say
Soil biologists stress that microbial amendments are not a silver bullet. Success depends on a host of factors: baseline soil biology, organic matter levels, pH, and how the product is applied. Many researchers advocate for field trials under local conditions to set realistic expectations.
Practitioners who adopt microbial products typically treat them as one tool among many — a complement to crop rotation, cover cropping, reduced tillage, and targeted nutrient management.
Questions to ask before trying microbial soil amendments
Managers considering Bio 800 or similar products should weigh the following practical points:
- What does independent trial data show for soils and crops similar to yours?
- How will the product fit into your existing fertility and pest management program?
- Are application methods and timing clearly defined for your operation?
- What baseline soil tests and monitoring will you use to measure impact?
Hausmann frames Bio 800 as an attempt to restore ecological function to soils that have been stressed by intensive management. For farmers, groundskeepers, and landscape managers navigating tighter budgets and tougher environmental rules, biologically based products offer a different path — one that focuses on rebuilding the living systems beneath our feet rather than only treating symptoms aboveground. The scientific community continues to evaluate how broadly and consistently those approaches translate into measurable, long-term gains.
