Dynamiting Subsoil of Cotton Field Doubles Crop 



WALHALLA, S. C, August 5, 1911. 



Gentlemen : I wish to tell you about my experience of using dynamite on 

 part of a field of cotton. The size of the plot was thirty feet by ninety feet. The 

 soil of the whole cotton field was given the usual cultivation before sowing the 

 seed. I am very greatly pleased to say that the small plot of dynamited soil has 

 shown a better crop, in fact the yield from this dynamited soil will be, in my judg- 

 ment, between 800 and 1,000 pounds per acre, or more than tivice as many pounds 

 of seed cotton as will be picked from the same size of plot adjoining the dynamited 

 plot. 



The success of this tested plot is so assured that I am going to use dynamite 

 on thirty to sixty acres of land now growing good crops. I feel that dynamiting 

 the subsoil of these acres is going to result in greater crops. I figure that I can 

 do this at a cost of four or five dollars an acre. In dry soil I use a quarter of a 

 dynamite cartridge in holes placed fifteen feet from each other. This takes forty- 

 nine sticks of cartridges of dynamite to the acre, approximately twenty-five pounds. 

 My test of dynamiting the cotton plot was the means of showing me how I can 

 make my acres grow bigger, better and more valuable crops at small cost and 

 increase the fertility of my farm.
