Precision-Engineered
Biological Soil Amendments
High-Performance Raw Materials for Industrial Blenders & Agricultural Partners
Moving beyond "waste." McNabb Broders utilizes advanced
In-Vessel Composting (IVC) to manufacture stable,
high-performance substrates for industrial soil blenders, professional growers and broad-acre agriculture.
IVC-38 Fines
3.07% Nitrogen. 5.0 pH.
3/8" Screened. The acidic neutralizer for high-performance soil blending.

IVC-ABM
Activated Bio-Mulch.
Fungal-dominant and pathogen-free. Superior biological structural material for industrial use.

IVC-FSB
Unscreened, 2-inch minus biological amendment. Engineered for broad-acre agriculture, high-volume soil carbon building (78% OM), and Climate-Smart cooperative partnerships

Industrial Substrate Manufacturing
McNabb Broders utilizes a controlled, closed-loop In-Vessel process to engineer consistent biological outcomes. We move beyond traditional composting to provide industrial-scale substrate manufacturing that meets the rigorous demands of professional soil blenders and agricultural engineers.

Feedstock Engineering
Comprehensive characterization
and preparation of industrial biomass. We precisely calibrate raw material profiles to ensure chemical consistency and biological purity for the IVC manufacturing process.

Residual Asset Management
A technical, compliance-first approach to industrial residuals and biosolids.
We provide documented management pathways that transform material liabilities into stabilized, high-value biological assets.

Precision Substrate Synthesis
Advanced manufacturing of high-performance biological substrates.
Our closed-loop IVC system produces standardized, fungal-dominant materials engineered for industrial stability
and structural performance.
The IVC Advantage:
Engineered Biological Stability
Traditional windrow composting is subject to environmental variables, moisture fluctuations, and inconsistent maturation. McNabb Broders utilizes a closed-loop In-Vessel Composting (IVC) system to manufacture climate-controlled biological stability. By eliminating external variables, we ensure every cubic yard meets rigorous industrial specifications for purity, maturity, and performance.

Our Legacy: A History of R&D
Our history as a multi-generational farm was our Research and Development era. Decades of land stewardship evolved into today's precision manufacturing. We combined multiple generations of biological knowledge with advanced In-Vessel Composting (IVC) technology to engineer the ultimate industrial substrates.


The Circular
Cooperative Partnership
We partner with industrial producers and agricultural cooperatives to close the supply-chain loop. By transforming regional ag-processing residuals into high-volume, stabilized biological amendments (IVC-FSB), we return precision-engineered soil carbon directly to your farmer-owners. Achieve your industrial ESG diversion goals while actively funding the next generation of Climate-Smart agriculture.
Contact McNabb Broders to discuss inbound material streams, ESG reporting, and substrate manufacturing solutions tailored to your operation.
