narrow and may be one-twentieth, one-sixteenth, 

 one-tenth, one eighth acre or larger. A plot one rod 

 wide and eight rods long will contain one-twentieth 

 acre. The width of the plot may be adjusted to ac- 

 commodate a certain number of rows of crop and 

 the length made proper to include an even fraction 

 of an acre. A strip three or four feet in width 

 should be left between each two plots. These strips 

 are to be left unfertilized and are for the purpose of 

 preventing one plot being affected by the plant food 

 of another. 



The plots are all plowed, planted and cared for 

 alike, the only difference in treatment being in the 

 application of plant food. If the plots are one- 

 twentieth acre in size, plant foods may be applied 

 as follows:
