What Treatment is Necded. 219 - 
Summary statement.—The  fruit-grower will no 
doubt desire to ask how he is to tell just what 
kind and what quantity of fertilizers to apply to 
his land. This is one of those questions which no 
person can answer for him. MHaving studied the 
matter carefully, and having observed his plantation 
from day to day and year to year, he should be 
able to discover about the treatment which it needs. 
As a general statement, it may be said that the 
fruit plantation which is giving satisfactory results 
is receiving the very treatment which it needs; but 
when it is giving unsatisfactory yields, some change 
in the management should be made. An_ orchard 
which is in sod and not doing well should certainly 
be plowed and tilled. One which is tilled and is not 
doing well may be benefited by seeding down, or 
it may not. If the growth is strong and rapid, and 
the trees or vines seem to be going to wood at the 
expense of fruit, then some check may be necessary. 
This check may be given by seeding down for a 
time, by giving somewhat less thorough or prolonged 
cultivation, or by the use of rather more mineral 
fertilizers and less nitrogenous ones. In all cases 
in which the growth is not sufficient and the leaves 
are yellow and drop early, it is probable that either 
more nitrogen or more moisture, or both, is needed. 
As a general principle, it may be said that nitrogen 
can be had in sufficient amount by thorough and 
judicious tillage, by the use of leguminous cover 
crops, and by stable manure. In some cases, how- 
ever, quicker and cheaper results may be had by
