into bloom. Thus the land may be prepared very 
much earlier for its destined crop of alfalfa. 
Alfalfa After Crimson Clover—Where the cli- 
mate is mild enough to permit its growth crimson 
clover forms an admirable preparatory crop for fall 
sown alfalfa. The subject is mentioned in an earlier 
chapter, but I will here sum up its advantages and 
manner of use. Crimson clover is an annual. Sown 
in the late summer it grows during the fall and 
whenever it can during warm days in winter. It 
makes very rapid growth in spring, blooms in May, 
ripens seed and dies. It is not a good clover for for- 
age unless fed off green. Half ripe crimson clover 
heads are dangerous when fed to animals, making 
‘hair balls’’ in their stomachs and killing them some- 
times. A fairly good crop of crimson clover will 
yield to the soil as much nitrogen as would cost $15 
per acre, if one were to purchase it in the bag. It 
comes off or goes under early enough to make easy 
the preparation of a good seedbed. There is seldom 
danger of insufficient moisture when crimson clover 
is the crop preceding alfalfa, supposing the land to 
be well managed after the clover is ready to turn 
under. 
On the other hand crimson clover does not thrive 
well without inoculation, and natural inoculation 
seems absent except along the Atlantic seaboard. 
Doubtless artificial soil inoculation would result in 
great gain with this plant elsewhere. Crimson clo- 
ver provides a great deal of very valuable humus.
