CK® Crop Kit™ NitroSulfix™

CK® Crop Kit™ NitroSulfix™ is a granular nitrogen fertilizer engineered for soil application where multi-nutrient correction and strong sulfur support are required. By coupling steady ammoniacal nitrogen with Fe and MgO enrichment and a reinforced SO₃ supply, NitroSulfix™ ensures vigorous vegetative growth, robust chlorophyll formation, and improved nutrient assimilation. Its higher sulfur concentration makes it especially suitable for soils or crops with elevated S demand (oilseeds, brassicas, cereals) and for alkaline or calcareous soils where sulfur-driven acidification improves Fe and P availability.
