Roots in the Buffer: Industrial Hemp as Riparian Soil Remediation, Functional Buffer Species, and Local Fiber Hub Catalyst at Family Farm Direct

Commodities

• Agronomic: hemp
• Animals: bovine

Practices

• Crop Production: cover crops, crop rotation, nutrient management
• Natural Resources/Environment: riparian buffers

Farmers across the Chesapeake Bay watershed face compounding pressure: degraded riparian buffers, compacted soils from legacy land use, nutrient-loading obligations under the Bay TMDL framework, and the persistent search for diversification crops that can carry their own economic weight. Industrial hemp has been proposed as a high-value fiber and soil-restorative crop, but regionally validated, plot-scale data on its performance in Mid-Atlantic riparian and compacted livestock ground does not yet exist.

This three-year project establishes a no-till industrial hemp trial on approximately four acres at Family Farm Direct, a livestock operation in Waynesboro, Pennsylvania, operated by Ben Barnett and affiliated with The Farm Legacy Foundation Inc. (501(c)(3)). The trial encompasses two contrasting treatment plots: a stream riparian buffer strip (muck soil, high organic matter, elevated pH) and a legacy-compacted horse paddock zone, both seeded with the same fiber hemp varietals using a leased 7.5-foot no-till drill. This paired design allows direct comparison of hemp's soil remediation capacity under two real-world soil conditions on a single working farm.

Soil health outcomes will be measured using the Cornell Soil Health Assessment (CASH) framework at baseline, mid-point, and close-out across both plots. Economic data will be collected annually using the American Farmland Trust Retrospective Soil Health Economic Calculator (R-SHEC), generating a standardized partial budget analysis for small-scale fiber hemp integration. Harvested hemp hurd will be evaluated for hempcrete aggregate specifications as the primary value-added end use, with equine bedding as a near-term revenue bridge.

Results will be shared through two on-farm field days co-hosted with Penn State Extension, presentations at the Pasa Sustainable Agriculture Conference (https://pasafarming.org/staff/), and two American Farmland Trust-style case studies distributed through the SARE project database and regional extension networks. The project positions SARE-funded data as the foundational proof-of-concept for subsequent state/federal equipment financing and a USDA Value-Added Producer Grant to establish a community hemp hurd processing hub.

The project directly contributes to SARE's legislative priorities by enhancing soil quality, supporting Chesapeake Bay water quality goals, improving farm profitability through diversification, and providing NRCS with the first systematic agronomic data toward potential recognition of industrial hemp as a functional riparian buffer species in the national USDA NRCS Environmental Quality Incentives Program (EQIP) Practice Standard library (https://www.nrcs.usda.gov/programs-initiatives/environmental-quality-incentives-program).

This project seeks to answer three interconnected questions:

1. Soil Health: Does no-till industrial hemp, seeded into a stream riparian muck zone and an adjacent legacy-compacted horse paddock, produce measurable improvements in biological, physical, and chemical soil health indicators across a three-year rotation, as measured by the Cornell Soil Health Assessment (CASH) framework?
2. Economics: What are the net input cost changes and partial budget outcomes associated with hemp integration at the 4-acre scale on a livestock farm, as quantified using the American Farmland Trust Retrospective Soil Health Economic Calculator (R-SHEC)?
3. Hub Viability: What is the yield, quality, and per-acre economics of hemp hurd produced from the trial site, and does it meet hempcrete aggregate specifications - with equine bedding as the near-term revenue bridge pending regional processor development and market need?

A fourth applied objective bridges research and policy: to generate the baseline agronomic and water quality dataset necessary to initiate dialogue with NRCS regarding evaluation of industrial hemp as a functional riparian buffer species eligible for EQIP Practice Standard consideration. The agronomic and water quality data generated by this trial is designed explicitly to initiate that policy conversation: without a baseline dataset demonstrating hemp's performance as a riparian zone plant - its root architecture, nutrient interception capacity, and biomass accumulation in saturated muck soils - there is no empirical foundation from which NRCS can evaluate a new practice standard. EQIP is the primary federal instrument through which riparian buffer establishment reaches working livestock farms at scale, providing cost-share payments for practices like Riparian Forest Buffer (Code 391) and proven pathways for integrating buffer installation into comprehensive conservation plans. Securing hemp's eligibility under EQIP would transform this trial from a single-farm demonstration into a replicable, financially accessible conservation tool for the thousands of livestock producers managing stream-adjacent paddocks and muck zones.
