| Περίληψη: | Manure solid-liquid separation offers a potential pathway for redistributing nutrients from livestock-intensive, nutrient-surplus regions to cropland with fertilizer demand, but the competitiveness of separated manure products with synthetic phosphorus fertilizer depends on manure quality, acquisition price, and hauling distance. We developed a probabilistic techno-economic framework to evaluate separated dairy manure solids (SDMS) relative to synthetic phosphorus fertilizer under representative market and agronomic conditions and to identify transaction-level thresholds for competitive viability. The analysis combined Sobol global sensitivity analysis, Monte Carlo uncertainty propagation, deterministic scenario surfaces, and leverage analysis. SDMS acquisition price was the dominant driver of variance in net savings, followed by P (Copyright © 2026 The Authors. Published by Elsevier Ltd.. All rights reserved.) |
