Project Details:

Many crops have been shown to respond to Cl - containing fertilizers. Both yield increases and a suppression of Physiological Leaf Spot symptoms have been reported when winter wheat has been fertilized with KCl in Montana.

There has been a large increase in interest in winter wheat production in Saskatchewan in the last few years. Part of this increased interest has been stimulated by the release of the high yielding semi-dwarf winter wheat cultivar, CDC Kestrel. Under favorable growing conditions, CDC Kestrel will often show strong Physiological Leaf Spot symptoms and preliminary observations suggest that these symptoms are suppressed by the addition of KCl fertilizer. It is also possible that CDC Kestrel and several other winter wheat cultivars could be excellent indicators of Cl deficient soils.
