The Nurseries of Orange Trees. 



Cultivation of 



Citrus Fruits Previous to planting, there should be thoroughly incor- 



~ " porated with the soil, for every 100 square yards: . 



Well-rotted barn-yard manure .... 1000 pounds 



Superphosphate of lime 50 " 



Sulphate of potash 20 " 



In spring, 50 pounds of nitrate of soda should be broad- 

 casted over the same area. 



In the second year, the same application may be re- 

 peated with the exception of the barn-yard manure. 



For the seed plot, a heavy dressing of barn-yard manure, 

 with the addition of a moderate application of superphos- 

 phate of lime, will suffice. 



In spring, the plot should be watered frequently with 

 a solution of one-half ounce of nitrate of soda in the gallon 

 of water. 



It should be borne in mind that increased applications 

 of fertilizers will not necessarily produce increased yields, 

 and that, once the limits are reached of what the plant can 

 assimilate and those limits are approximately represented 

 by the quantities indicated in the formulae given above 

 any surplus that may be employed will be unproductive of 

 good and economical results. 



Time and Manner of Application 

 of Fertilizers. 



If any barn-yard manure is to be applied, it should be 

 turned under at the time of the ploughing which is usually 

 given shortly after the crop is gathered. 



The superphosphate and potash salts should be culti- 

 vated in during the dormant season of the trees, or, at latest, 

 sometime before active vegetation commences in the spring, 



The nitrate of soda should be broad-casted in three 

 successive dressings, as follows: A third-part at the outset 

 of vegetation in the spring; another third-part at least a 

 fortnight before flowering commences, and the remaining 

 third-part sometime after the fruit is well set. After each 

 dressing, shallow cultivation and irrigation may follow with 

 advantage.
