B. For use in connection with manure: 



1. On clover sod or soils rich in humus : 

 In each loo pounds: 



Nitrate of soda, 8 lbs. 



Dried blood, 5 lbs. 



Acid phosphate, 60 lbs. 



High grade sulfate of potash, 27 lbs. 

 Use 600 to 1000 pounds per acre, varying with quantity of 

 manure used. 



2. On lighter and poorer soils : 

 In each 100 pounds: 



Nitrate of soda, 8 lbs. 



Dried blood, 10 lbs. 



Tankage, 20 lbs. ^ 



Acid phosphate, 40 lbs. 



High grade sulfate of potash, 22 lbs. 

 Use 800 to 1200 pounds per acre, varying with quantity of 

 manure used. 

 Conditions under which Muriate of Potash may be Substituted 

 for Sulfate : If the soil on which potatoes are to be grown is of 

 coarse texture and deficient in capacity to retain water and if experi- 

 ence indicates a considerable probability that the crop at some per- 

 iod in its growth will sufifer from drouth, it may be wise to substitute 

 muriate of potash for the high grade sulfate recommended in any of 

 the above mixtures. As already indicated, the substitution of muri- 

 ate for the high grade sulfate may be especially advisable if in addi- 

 tion to being light, the soil is naturally rich in lime. 



Method of Applying : If the potatoes are to be planted by hand, 

 good results may be obtained by opening the furrows and then scat- 

 tering the material widely the full length of the furrow, making it 

 cover not only the entire furrow, but a space a few inches in width 

 on each side. If spread in this way, the fertilizer will not be so 

 thick that it will be necessary to take any special steps to mix it with 

 the soil. It will be sufficiently mixed in covering the seed. If plant- 

 ing is done by machine, the fertilizer attachment of the machine 

 should be one which scatters the fertilizer over a relatively wide 

 area. If such a n.iachine cannot be used, it may be best to withold 

 a portion of the fertilizer until the crop is three or four inches high, 

 when it should be scattered along strips ten to twelve inches wide on 

 either side of the row and cultivated in.
