Microessentials® SZ fusion technology fertilizer
MicroEssentials® SZ uses Mosaic's proprietary Fusion® technology to fuse N, P, S, and Zn into a single balanced granule. Dual sulfur forms provide season-long availability. 15+ years of independent field data: +7.2 bu/ac corn vs. MAP.
Overview
Conventional fertilizer blends distribute nutrients unevenly because different-sized granules separate during handling. Fusion technology chemically fuses four nutrients into every granule, ensuring balanced nutrition from the fertilizer band in each plant's root zone. Dual-form sulfur delivery provides sulfate sulfur for immediate early-season uptake and elemental sulfur that oxidizes gradually through the season. MicroEssentials SZ is labeled as an Enhanced Efficiency Fertilizer (EEF) and eligible for USDA NRCS conservation programs.
