     if you are in a highly alkaline location you likely   
   do not need any more salts or calcium.  instead look   
   to growing organic materials that will eventually end   
   up being turned into humus.  if you can salvage any   
   clean organic materials and get them used as mulch or   
   compost them you will instead be building topsoil and   
   building on top of that alkaline base.  protect it   
   from the wind and getting blown or washed away.   
      
     elemental sulfur may likely be much more economical   
   as an acidifier.
