Saline seeps appear where glacial till overlays an impermeable layer. During fallow, increased
  percolation picks up salts and carries them deeper into the soil. When salty water reaches the tight
  layer, it spreads out sideways, flowing downslope underground. The salty water seeps to the surface on
  a lower field and the water evaporates leaving salt on the soil surface.

Current research shows equivalent yields from conventional and conservation tillage if known
