to prevent the fertilizer used on one plot from affecting the 

 adjoining plots. 



The fertilizers should be applied as illustrated in the diagram. 

 They can be mixed with fine earth and drilled in the rows. The 

 plots should be cultivated in the same 

 way and planted in the same crop, the 

 one for which the farmer usually buys 

 fertilizers. If he uses them largely on 

 several crops, it will prove helpful and 

 economical to make the test for each 

 one. If potatoes or tobacco be the 

 test crop, sulphate of potash should be 

 used instead of muriate of potash. 



The test plots may be made smaller, 

 the quantity of fertilizers being reduced 

 accordingly. 



Cost of Fertilizers. In buying or 

 in mixing fertilizers, the farmer should 

 try to get as many pounds of available 

 plant food as possible for the money, 

 not as many bags of material. The 

 freight and trouble of handling a ton 

 of kainit containing one hundred and 

 twenty pounds of plant food are as 

 great as those on a ton of muriate of 

 potash containing a thousand pounds. 

 A fertilizer at forty dollars the ton 

 may be, and often is, cheaper than 

 one at twenty dollars the ton, on account of supplying over twice 

 as much plant food at the same cost for freight and hauling.
