US phosphate: Mosaic curtails, citing limited affordable sulfur; US sulfur and phosphate exports are up in 2026

“Fertilizers - Shipments decreased as higher input costs led to reduced fertilizer demand.” — source, 2026-11-13

The third-quarter 10-Q reports lower fertilizer shipments on higher input costs, and the phosphate producer's 10-K names this railroad as the rail carrier serving its Florida mines. Inferred: curtailed Florida output means fewer phosphate rock and fertilizer carloads in central Florida; the filing does not separate phosphate from other fertilizers or name sulfur.
