Alfalia 
CULTURE—Alfalfa Seed may be sown either in spring or in fall at the 
rate of 12 to 20 pounds per acre. 
grains aS a nurse crop, sowing only about half the amount of grain per 
acre, so that the grain will not be too thick to smother out the alfalfa. 
Alfalfa is the great hay crop for America and can be successfully grown in many 
localities. Alfalfa is of two types, the Domestic or Common which has a long tap 
root which penetrates into the soil for a distance of 8 to 10 feet, and the Grimm 
Type, which has a spreading root system. The Grimm Type is considered: the 
hardiest although on certain soils and in certain localities the Hardy Common 
varieties will stand extremes of heat and cold equally well. 
All our Domestic Alfalfa Seed is especially selected for Adaptability, 
Sow with oats, barley, field peas or other 
Hardiness, and is of U. S. Verified Origin.

GRIMM ALFALFA (Blue Tag Grade)—State sealed 
Grimm Alfalfa is the hardiest of the hardy alfalfas 
and differs from the domestic or common: variety 
in that it has a spreading root system instead of 
the long tap root which is sometimes broken 
when the ground bulges, during the spring freezes, 
thus causing the plant to die. Highest grade seed.

cipally in the mountainous districts in northwest- 
ern Colorado in Moffat, Routt and Rio Blanco 
counties, under the mosit rigorous climatic condi- 
tions. Very hardy and will produce as fine a hay 
crop as the registered seed.

LADAK—A wilt-resistant variety adapted to a wide 
range of conditions. Ladak is slow to start in the 
spring, but produces a large first cutting. It re- 
sists drought and produces a good yield of hay 
when other varieties are practically at a stand- 
still. The hay is leafy and of high feeding value, 
and will hold a stand from one to two years 
longer than other varieties.

ARGENTINE ALFALFA—tThis is imported from 
Argentina in South America, grown in Rio Hondo 
Province 89° Latitude South. Denver is 40° North. 
Argentine seed should be comparable with seed 
grown in the southern half of Colorado and similar 
latitudes. It is similar in type to our Common 
Alfalfa, except that it grows taller and is coarser. 
Stems are leafy and produce more tonnage per 
acre. It is well liked by growers who have tried 
it. Imported seed is stained 10% Orange-Red as 
required by government regulations. Not approved 
for Soil Conservation in Colorado.
