Full explanation
Trade names: ESN (Nutrien, polymer-coated, temperature-responsive), Agrium Duration (PCU), Polyon (Harrell's, decorative crops). In Ukraine — niche product: premium segment for intensive orchards, vineyards, greenhouse crops, and turf (football pitches, parks). For field crops like corn and sunflower it's too expensive — doesn't pay back. April 2026 price: +25–60% over standard urea [VERIFY]. Mechanism: coating regulates release rate via shell thickness, soil pH, temperature, and moisture. PCU is most precise — release is proportional to temperature (matching plant growth). SCU is cheaper — mimics 'candles' where sulfur shells are pierced by rainfall. Trade-off: cuts need for split applications 40–60%, but high CAPEX. For standard Steppe and Forest-Steppe cereals, combining regular urea with NBPT + DMPP delivers a similar effect at lower cost.
