Compendium of soybean diseases. Part II. Non-infectious diseases: air pollutants; mineral deficiencies and toxicities
Soybeans are not as sensitive to ozone and sulfur dioxide as alfalfa, clovers, and peanuts. Foliar sensitivity is related to genetic materials, cultivars, and environmental factors that contribute to good plant growth. Specific symptoms of fluoride injury on soybeans is unknown. Nearly fully expanded leaves are most sensitive to ammonia. Soybean leaves of all ages show characteristic symptoms of carbaryl, and dicofol injury is associated with fully expanded soybean leaves. Mineral deficiencies are most common in sandy, weathered, and highly organic soils exposed to abundant rainfall or heavy irrigation. Nitrogen-deficient plants become pale green; soybeans require relatively large amounts of phosphorus with symptoms of its deficiency not well defined. Soybeans require large amounts of potassium, calcium, and magnesium. The symptoms of these mineral deficiencies include small, yellow-green leaves and yellowing of interveinal areas on younger leaves. Manganese and zinc toxicity were discussed. Soybeans are relatively tolerant to boron. 3 references, 1 figure, 1 table.
