Ga old worn soils of Southern New
Eogland it has been found that Cal.
cium, or lime, is a dominant element
owing, doubtless, to it's having been ex'
hausted. This is necessarily a promi
nent ingredient OF the phoephaEes and
need not be taken into consideration
where acid phosphate is used. One Of
the principal places where lime may be
used is in situations where the soil is
rich in humus and water and the free
gro With of plants has been checked by
the cold, sour conditions thus estab
lished, Turning up this soil and lin
ing it freely, 1000 to 8 600 pounds per

amounts of water, GrIm5 ID found
some soils responsive to app ications of
ferrous sulphate, copperas, sulphate OF
iron. This was doubtless due to lack
of iron, the action of the sulohuric ACID
on other soil compounds and perhaps
to some lack of sulphuric acid itself
which furnishes sulphur.
Some one may wish to know how to
prepare a home mixture, OF to selec a
commercial manure so as to present q
given amount of the special elements
tor the use Of plants. Toe commercial
articles are given in per centages If
1t is desired to apply 90 pounds Of
nitrogen, 40 pounds of potash and 80
pounds Of phosphoric acid from an
ammoniated guano as many hundred
pounds must be used as multiplied into
the per centsges given on the bag will
approximate the amount desired to
use.
