FORMULAS FOR USE IN HOME MIXING. 



The following materials and proportions are suggested for use under different 

 conditions : 



A. Where fertilizers only are to be employed : 



1. On clover sod or soils rich in humus and in high fertility. 



In each 100 pounds — 



Nitrate of soda, 7 lbs. 



Sulfate of ammonia, 4 



Cyanamid, 4 " 



Tankage, 15 



Acid phosphate (14%), 50 " 



High grade sulfate of potash, 20 " 



Use 1500 to 2000 pounds per acre. 



This mixture will have about the following composition: Nitrogen, iA%:, 

 phosphoric acid, 8.5%; potash, 10"/o. 



2. On lighter and poorer soils: 

 In each 100 pounds — 



Nitrate of soda, 12 lbs. 



Sulfate of ammonia, 8 " 



Cyanamid, 5 " 



Tankage, 20 " 



Acid phosphate (14%), 35 " 



High grade sulfate of potash, 20 " 

 Use 1500 to 2000 pounds per acre 



This mixture will have about the following composition : Nitrogen, SA% ; 

 phosphoric acid, 6.9%; potash, 10%. 



In putting these materials together it is recommended that the cyanamid and 

 acid phosphate be mixed first, as it is believed that this will be certain to pre- 

 vent any loss of ammonia from the sulfate of ammonia and tankage which are 

 later added. 



B. For use in connection with manure : 



1. On clover sod or soils rich in humus : 

 In each 100 pounds — 



Nitrate of soda, 8 lbs. 



Sulfate of ammonia, 4 " 



Acid phosphate (14%), 60 " 



High grade sulfate of potash, 28 " 



Use 600 to 800 pounds per acre, varying with quantity of manure used. 

 This mixture will have about the following composition: Nitrogen, 2.04%; 

 phosphoric acid, 8.4%,; potash, 14%. 



2. On lighter and poorer soils: 

 In each 100 pounds — 



Nitrate of soda, 8 lbs. 



Sulfate of ammonia, 6 " 



Tankage, 20 " 



Acid phosphate (14%), 40 " 



High grade sulfate of potash, 26 " 



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

 This mixture will have about the following composition : Nitrogen, 3.64% ; 

 phosphoric acid, 8.4%; potash, 13%. 



If the potatoes are to be planted by hand, good results may be 

 Method of obtained by opening the furrows and then scattering the ma- 

 Application, terials 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 planting is done by macliine, the fertilizer attach- 

 ment of the machine should be one which scatters the fertilizer over a relatively 

 wide area. If such a machine cannot be used, it may be best to withhold a por- 

 tion of the fertilizer until the crop is three or four inches high, when it should be 

 scattered along strips ten or twelve inches wide on either side of the row and 

 cultivated in.
