Sulfur-Coated Urea - an overview ScienceDirect Topics

Sulfur-coated urea (SCU) was one of the first CRFs. It was manufactured by the Tennessee Valley Authority [13, 14]. SCU was prepared by coating preheated urea granules with elemental sulfur called molten sulfur. Sulfur is a low-cost plant macronutrient and is suitable for fertilizer coating because of its ability to melt at about 156C.Sulfur coated urea is a commonly used product in lawn Jul 06, 2012 Sulfur Coated Urea (SCU) When sulfur coated urea technology was first developed, sulfur was chosen as the dominant coating material because of its low-cost.
