A digital manure brokerage for medium/large livestock farms and crop growers, optimizing the trade of animal waste as a regulated fertilizer. Rising synthetic fertilizer prices, environmental rules on runoff, and carbon-accounting pressures are pushing demand, yet most manure still moves via phone calls and opaque local deals. NutriManure Hub uses soil tests, manure analyses, and GIS to broker nutrient-matched contracts by: - pricing NPK value vs. hauling distance and local fertilizer benchmarks - bundling permits, transport, and spreading services into a single contract - generating reg-compliant nutrient management records for auditors and lenders - offering forecast tools to integrate into farm-management software. It monetizes via per-ton brokerage fees and premium SaaS for large integrators, with defensibility in regional network effects and regulatory integrations that are painful to replicate.
