Poorly drained potholes in glacial landscapes often have localized areas that have temporary high water tables. Excess soluble salts will often crystallize on the surface of fallow fields. Thick continuous crusts form in saline seeps. Thin patchy salt crusts will form under clods or on the shady side of clods where marginal salt problems are found. Patterns of growth in cropped fields will be poor, spotty stand establishment.
Saline soils tend to inhibit germination and emergence of cereal grains.
