Plants are all over the map when it comes to 'salt tolerance' so there is no one good answer.    Sandy soils are more difficult to manage for salts since they do not buffer very well, and some plants can tolerate a lot of salts, ie Sweet Corn or Potatoes.  Best to follow the recommended rates as promoted by your local Land Grant College Extension, and adjust lower for sandy soils and higher for heavy/organic soils.

Find out if you are growing a 'salt sensitive' crop and do not over fertilize.

You could perhaps plant a temp cover crop to soak up the excessive salts for a time, like buckwheat.

   If your plant needs fertilizer and you fertilize it, it usually takes
eight days for the fertilized plant to show signs of being fertilized.  If
you over fertilize, the effect may appear sooner.  If over fertilized and
you want to save the plant, stir in copious amounts of gypsum into the soil
and water profusely.  This technique usually works with potted plants and
can also work if planted outside in well drained soil.  It'll take time but
plants often restore their health.
   Most of the cases of over fertilization I hear about is from users of
'Miracle-Gro.'  I warn my students to not use it or any high nitrogen
fertilizer -or - if they do continue to use it, water with 1/2 teaspoon (the
little end of the plastic spoon that comes with Miracle-Gro) per gallon of
water every)(!) time they water the plant.
