COMPLETE FERTILIZERS FOR FRUIT. 



N the composition of the commercial fertilizers now in the mar- 

 ket, the fact is recognized that nitrogen, phosphoric acid and 

 potash are the chief constituents of plant food. But in com- 

 bining them the manufacturers, in most instances, fail to embody 

 any distinct principle or rule of practice. Order will come out 

 of this chaos, through the efforts of those who use the various 

 preparations of plant food. 



The time is coming when the general farmer, or the market gardener, will 

 order of the dealer so many pounds each of nitrogen, phosphoric acid and 

 potash, just as now he purchases seeds and foods. 



As a suggestion to those who are inclined to mix their own fertilizers, or 

 ask for a definite mixture from the dealer, I offer the following combinations, 

 which may be varied ad libitum : 



No. 1 

 Nitrate of soda 15% nitrogen 350 lbs. 



Dried blood j'S" i ". •"■ 'i" ItOO „ 



\ 2 I. phosphoric acid j 



Acid Phosphate 15 n i. i. 700 m 



Sulphate of potash 50 n potash 250 n 



This combination would contain the following : 



Nitrogen 122 lbs., or 6 1 % 



Phosphoric Acid 119 n or 5 9 ., 



Potash 125 .. or 6.2 „ 



No 2. 



Sulphate of Ammonia 20% nitrogen. 250 lbs. 



) 6.75,, \ 



Cotton Seed Meal |- 2.75 ,, phosphoric acid > 1000 \^ 



) 1.75 I, potash ) 



Acid phosphate 15 „ i, 550 n 



Muriate of potash 50 n n 200 n 



This combination would contain the following : 



Nitrogen 117 lbs., or 5.85% 



Phosphoric acid 110 „ or 5. 5 n 



Potash 117 M or 5.85,, 



No. 3. 

 Nitrate of soda 15 % nitrogen 300 lbs. 



Dried blood V2 " , ", : ••.•,• IgOO .. 



J 2 M phosphoric acid J 



Dissolved bone Vo r " n. " IsOO ,. 



/ 2.5 II nitrogen. 

 Sulphate of potash 50 , 300 ,, 



This combination would contain the following : 



Nitrogen 125 lbs., or 6.25% 



Phosphoric acid 124 i, or 6. 2 ,, 



Potash 150 1, or 7. 5 „ 



No. 2 would furnish plant food more cheaply that either of the others at 

 this time, owing to the low price of cotton seed meal.
