Du Pont's great ideas, copyright 1910.

io9 says --

While dynamite was certainly a common enough tool in early 20th century American agriculture, it appears that Du Pont's claims about dynamite's transformative powers on soil were a wee bit overstated. In fact, Du Pont sponsored a study from 1911 to 1913 to determine the effects of dynamite on soil, and found no significant improvement in crop yields, moisture, or nitrate levels from dynamited soil. On top of that, two years down the road, the soil that had been dynamited was in a poorer physical condition than soil that hadn't been dynamited, described as "compacted and puddled." Plus, dynamiting wasn't cheap at $12.20 per acre for dynamite and an additional $5 per acre for labor.
