Salt Tolerant Alfalfa FSG 423ST was selected for persistence and high forage yield from parent plants growing in the saline soils of the northern Great Plains. Due to it’s tolerance to saline soils, branching/tap root system, and great disease resistance package, FSG 423ST produces high quality, fine stemmed hay and tolerates variable soil types. It is adapted to the Great Plains, North Central Region and the winterhardy Intermountain Region of the United States. But FSG423 is just for saline soil conditions; it is an excellent choice for any area where a high yielding, superior forage quality alfalfa variety is desired.

The vast majority of soils in the Great Basin province and Intermountain West are above 7 on the pH scale and high in salt. 423ST should find broad appeal in these areas. If you are considering a seed mixture or pasture, please visit our Salt and Alkali tolerant seed page for suggestions and help. Consider using Salt Tolerant FSG 423ST as a component of your mix.
