ty or more plants, costing approx
mately $4,000 and having an operating
capital OF about $25 900 each to produce
I the quantity needed for agriculture.
This would involve the assumption
that the commercial phases Of the prob
lem were satisfactorily solved. Even if
the requisite funds were available, it
is a question whether operations
could begin in time to provide an ade-
quate supply for the coming year. The
department is investigating all as
poets of the, question and is planning
to send experts to California to study
the situation and especially to con-
slider possibilities of production on q
commercial scale. ~,
The Phosphate Situation.
Acid phosphate is the basis of near
ly all commercial mixed fertilizers.
1t is made by the action of sulphuric
acid upon phosphate rock Our avail
able sources of phosphate rock are
greater than those of any other ma
ton. The main supply for domestic
consumption and for .exportation
comes from Tennessee, South Caro-
lima and Florida.
In 1914, 2,734,00O tons of phosphate
rock were produced in this country.
Up to that year about one-half the
quantity mined was exported to Eu-
rope. The rock in it's natural state
is not readily absorbed as plant
food. 1t is made available for this
purpose by treatment with sulphuric
acid, about one ton of the acid being
used to ton Of phosphate rock. When
thus treated, a super-phosphate con.

zinc. or copper smelling companies
using sulphidez ores have sulphuric
acid plants, in connection. with Their.
smelters. The fumes. discharged into.
the atmosphere by these smelters are
sufficient to produce many thousands
of tons OF sulphuric acid daily. Under
normal conditions, the limited market
for the acid and the long haul sneces:

it commercially impracticable to con

The erection of acid plants of SUI.
ficient capacity to convert the smelter
gases would involve an outlay. Of at
least several million dollars. Under
normal conditions it would take four
months to complete the plants. In
the present situation, at least six
months would be required. The blu.
reau Of soils estimates that sulpburic
acid could be made by some of the
western smelling plants at approx
mately one.half the normal cost Of pro-
ducing the acid in the East where
pyrites are used The saving in cost OF
manufacture in the West, however.
would be partly Offset by the long
haul necessary to bring the acid to
the eastern market.
In view of the difficulties In the way
OF the production and utilization of
sulphuric acid for fertilizer purposes,
the bureau of soils has endeavored
to develop q commercial method, ill.,
volving the use of the electric fur
mace, for manufacturing phosph0ric
acid, which can be used as a substi-
tute. Through this method double
super.phosphate, which will contain 40
to SO per cent of water-soluble phos-
phoric acid, or the still more concen-
trated form OF ammonium phosphate,
could be secured. But the use of the
electric furnace for the purpose is
commercially feasible only where
phosphate rock coal, and cheap water
power are readily available. The de-
partment is investigating this matter
to ascertain whether there are local.
tiles where these conditions exist and
where, therefore. double super-phos-
plate may, be made.
The Nitrogen Situation.
The nitrogen situation is Of less
pressing concern. Cottonseed meal
forms the bulk of the heterogeneous sub
stances entering into commercial fer
tilizers. The amount available for
fertilizer use Is dependent upon the
annual production of cotton and the
demand for the meal for feeding stuffs.
The supply of dried blood and tank.
age, also sources of heterogeneous ma.
terial, is dependent upon the number
of animals slaughtered. Only few
large packing concerns conserve these
products, which are now used to a
considerable extent as cattle feed as
we'll as for fertilizer purposes. In.
