uble forms of plant food may be diff
fused and distributed through the soil
and also how some of the more soluble
materials, such as nitrates, may be
leached from soils, especially in the
case of sandy soils that are not under
laid by retentive. olayey subsoils
Discussion of some of the principal
heterogeneous fertilizers, with reference to
their composition and relative availabili-
ty, followed. Special attention was CIV
en- to calcium cyanamid, commonly
known as lime nitrogen, as this particu-
lar form of nitrogen has aroused much
interest in recent years by reason of the
fact that atmospheric nitrogen Is used
in rs production, the process being car
ried~ out by the employment of an cleo
trio current of high voltage.
1t was noted that the company owning
the rights to manufacture this material
in the United States was interested in
the development of one or more large
water power sites in Alabama so that
1t Is possible that a great industry of
vast economic and agricultural import
ance may eventually be developed in
this state
Regarding Potato Culture
