FARM AND -SCHOOL PROBLEMS. 



Thus you are providing a ton of fertilizer having the de- 

 sired composition, and best of all, you have made it yourself and 

 know what there is in it. 



If the purchaser of commercial fertilizers will observe the 

 suggestions herein set forth he will be able to compound for 

 himself any grade of fertilizer desired, and also one which will 

 meet the actual needs of his particular soil and system of crop- 

 ping, whether the fertilizer be for general or special use. 



Table for Home Mixing of Fertilizers. 



EXAMPLE: To make a 2-8-10 fertilizer from Nitrate of Soda, 16 

 per cent Acid Phosphate and Muriate of Potash. By looking in the 

 Percentage column for 2 per cent, in the Nitrate Soda column we find 

 220 bis., in the 16 per cent Acid Phosphate column opposite 8 per cent 

 we find 1,000 Ibs., and in the Muriate of Potash column opposite 10 per 

 cent we find 400 Ibs. The sum of these amounts would make 1,620 Ibs. 

 containing the same amount of plant food as a ton of 2-8-10 factory- 

 made fertilizer. 



Approximate cost of a 2-8-10 home mixed fertilizer : 

 220 Ibs. -Nitrate of Soda @ $55 00 per ton $5 94 



1000 Ibs. Acid Phosphate @ 14 00 per ton 7 00 



400 Ibs. Muriate of Potash @ 45 00 per ton 9 00
