Iron Deficiency & Symptoms in Texas Field Crops
Distinct iron chlorosis in plant leaves makes diagnosis easier Dr. Calvin Trostle, Extension Agronomy/TAMU Dept. of Soil & Crop Sciences, Lubbock, (806) 746-6101, ctrostle@ag.tamu.edu December 2023 Culberson Co. ag. agent Zach Schaefer and I visited this sorghum/sudan field in early September (Fig. 1). From the road it was evident much of this field was heavily iron deficient. This issue is most common in Texas sorghums, both grain and forages, as all sorghums have poor iron uptake efficiency relative to other crops. Fig. 1. Yellow plants… Read More →
Iron (Fe) Deficiency in Texas Crops Made Worse by Wet Weather

Many crops will show signs of nutrient deficiency under such conditions. These include iron (Fe) and nitrogen. Symptoms for N and Fe nutrient deficiency may be confused with each other. Nitrogen is mobile within the plant. N deficiency leaf symptoms are expressed in older leaves. This is usually a broad… Read More →
