Relation of Sulphur to Alfalfa Production 
947 
SUMMARY 
The data presented in these investi¬ 
gations show that the type of soil used 
in these experiments' contained as 
much of the common fertilizing ele¬ 
ments as the average Kansas soil 
and the sulphur content to be a little 
higher than the average. 
Sulphur applied to alfalfa has given 
no marked increase in yield or root 
development. This means that sul¬ 
phur is not the limiting factor in alfalfa 
production on the type of soil used in 
this experiment. 
In general, the acidity of the soil was 
increased by the sulphur, evidence that 
it should be supplemented with lime. 
The nitrogen content of the tops, 
and the sulphur content of roots and 
tops were not influenced by the sulphur 
applied. 
There was not a material increase in 
root development nor any increase in 
number or size of nodules on the 
roots as a result of sulphur applications.
