Declining Atmospheric Sulphur Deposition Drives Agronomic Demand
Decades of cleaner industrial and power generation emission standards have sharply reduced atmospheric sulphur deposition that historically supplied a meaningful share of crop sulphur nutrition for free, creating genuine and increasingly documented soil sulphur deficiency across major agricultural regions that previously never required supplemental sulphur fertilization. Agronomists increasingly recommend sulphur coated urea specifically to address this deficiency, since it delivers both nitrogen and sulphur in a single application rather than requiring separate sulphur fertilizer purchases and application passes. This trend has proven durable, since the underlying cause, cleaner air, shows no sign of reversing while soil reserves continue depleting.
