Iron Deficiency Chlorosis/Salt (IDC/SALT):

Iron Deficiency Chlorosis occurs on soils high in pH. Early in the season, new leaves turn yellow between the veins and, in severe cases, the leaf tissue turns brown and drops out. Soybean products are assigned scores based upon their tolerance to Iron Deficiency Chlorosis in field conditions. Soybeans rated with a nine (9) exhibit the highest degree of tolerance to chlorosis; varieties with a score of one (1) are the most susceptible to chlorosis and are not recommended for high pH soils.

Irrigation

The irrigation score is designed to reflect a hybrid’s response to irrigation systems.
