218 The Principles of Fruit-growing. 
sufficiency of lime as plant-food, apply lime at the 
rate of twenty-five bushels per acre once in five 
years. To provide, in addition, an abundance of all 
forms of available plant-food at the times needed 
for the development of the tree and fruit, apply 
annually chemical fertilizers in the following pro- 
portions :

“The amounts to be applied depend upon the 
character of the soils, as previously outlined, the 
kind of fruit, and the age and vigor of the tree; 
these given perhaps mark the minimum. 
“In a number of best orchards the quantities 
applied are very much larger than is here indicated, 
and the larger application is believed by the grow- 
ers to be proportionately profitable. 
“By the recent introduction of crimson clover, 
we have a plant admirably adapted to supply cheaply 
nitrogenous vegetable matter for orchards, and _ its 
growth is to be recommended wherever the plant 
ean be successfully grown, instead of the use of 
barnyard manure, particularly upon the poorest soils, 
until they are abundantly supplied with vegetable 
matter. The clover should be plowed down early in 
the season, in order not to retard the spring growth 
of the trees. Where the conditions are favorable 
for the growth of clover, the application of nitrate 
of soda may be omitted.”
