Ladak II Alfalfa is specialized for use on rangeland and dryland pastures from the northern plains to the winterhardy intermountain areas of the west where rainfall is limited for extended periods of time. Ladak 2 alfalfa is the superior choice for dryland applications. It is commonly used in grass mixes improving improved pasture applications. Performs very well in harsh soils and adverse conditions. It is drought tolerant and has an edge over Ranger Alfalfa in arid conditions. It has a deep tap root. Demonstrates very good winter hardiness with a fall dormancy 3.

The original USDA public Ladak strain has long been a favorite of farmers and ranchers in the intermountain west for arid sites. Widely used at the Utah Great Basin Research Station in range seeding and by the BLM Boise Regional Seed Warehouse. The original strain was slow to recover between cuttings. Ladak II alfalfa is an improvement on the original strain, developed from plants selected out of a 27 year old stand in eastern Washington. Ladak II Alfalfa has the drought tolerance of Ladak with improved disease and nematode resistance for increased persistence and adaption to a wider range of soil conditions.

Our Certified Ladak 2 is an improvement on the original and is a stonger dryland performer than Ranger Alfalfa.
