Iron Deficiency of Crops Food and Fertilizer Technology New Approach to Nitrogen Control in EAF Steelmaking

Iron deficiency can easily be mistaken for nitrogen deficiency However nitrogen deficiency affects the older leaves first while iron deficiency affects the emerging leaves first Plate 1 and Plate 2 Soil Conditions Likely to Produce Iron Deficiency in Rice The iron requirement of result whist steel produced from Oxygen steelmaking contains 30 to 40ppm nitrogen levels in steel produce from EAF is typically in the range 70 to 100ppm As mini mill operators have made the move from long products traditionally associated with EAF production 2 to the more high value flat product range the issue of nitrogen control
