Sulfur Deficiency and Fertilizing for Winter Wheat
eKonomics News Team
Sulfur deficiency in winter wheat is becoming more common in much of the Midwest. In Kansas, there are two main causes of sulfur deficiency: low sulfur inputs from atmospheric deposition and sulfur fertilizer or cooler soil temperatures as a result of no-till seeding.
Sulfur deficiency symptoms generally show up in the spring following green-up. At this growth stage, winter wheat begins rapid growth with stems elongating prior to jointing. Deficiency symptoms include stunted growth and yellowing of the younger or uppermost leaves. Since sulfur is mobile in the soil, symptoms tend to appear where soil erosion or leaching have occurred.
