Greening the Marble Sills: Big Sycamore Creek & Clinch River

Introduction: As the Big Sycamore Creek region emerges as a hotspot for sustainable mineral development, researchers and conservationists are eyeing a surprising natural ally in the pursuit of marble regeneration and carbon sequestration—plants.

1. Plants That Encourage Carbonate Precipitation

Some plants promote biological conditions for carbonate deposition through root-zone alkalinity, transpiration-driven ion concentration, or the release of calcium-binding organic acids:

• Bamboo (Phyllostachys spp.): Stabilizes marble-prone soils and mobilizes calcium through fast root growth.
• Switchgrass (Panicum virgatum): Native and effective in carbon drawdown and soil stabilization.
• Alfalfa (Medicago sativa): Enhances calcium carbonate availability and soil fertility.

2. Plants Supporting Geological Seeding & Reduced Atmospheric CO₂

• Hemp (Cannabis sativa): Excellent for phytoremediation and mineral accumulation.
• Chicory (Cichorium intybus): Enhances weathering of carbonate rock with deep-root organic acids.
• Moringa (Moringa oleifera): Releases chelators aiding calcium and magnesium binding.

3. Dual Benefit: CO₂ Drawdown + Marble Seeding

These plants aid:

• Biomass-driven carbon storage
• Organic matter cycling and root respiration
• Improved soil structure for mineral uptake

Conclusion

In the sills from Big Sycamore Creek to the Clinch River Basin, the right plant choices can drive marble nucleation, erosion control, and CO₂ sequestration. These species support a vision where ecology meets geology, nurturing sustainability and industrial potential in East Tennessee.

Hemp fiber, seed and oil can be used for a number of hemp products from summer sandals and purses, textiles like upholstery, carpets, curtains, door draft stoppers and a variety of designer sleeves for commercial products, posters, coasters, placemats and cardboard boxes.
