Iowa corn yield data from 132 comparisons of soil treatment with plots receiving no soil insecticide collected over a 20-year period indicated an 8.0 bu/acre increase in favor of aldrin or heptachlor treatment plots of corn following corn. In fields of corn following a crop other than corn, the treated plots averaged 8.7 bu/acre increase in 56 comparisons.

In a series of empirical comparisons involving producers from a cross section of the representative soil types of Iowa, information from 939 fields of first-year corn indicated a 9.3 bu/acre increase in favor of aldrin treatment vs. no treatment. These increases occurred on the best as well as on the poorest soils.

A 1964 sampling of corn growers throughout Iowa indicated that most soil insecticide users farmed more acres than did their nonuser neighbors. In the 30–39 age group, this was an increase of 62% in favor of users of soil insecticides.
