AN EXPERIMENTAL CULTIVATOR FOR ELIMINATING SOIL-SURFACE COMPACTION BY TRACTORS THE literature is replete with records of experiments which have led to the conclusion that the main reason for cultivating is to control weeds and conserve moisture (4). If the earlier experiments by Mosier and Gustafson (2) are examined closely, one learns that the plots were kept weed free by scraping or quick-chopping. They described the method as "scraping with a sharp hoe so as to produce practically no mulch". Gates and Cox (1) used this same method and stated "particular care was to be paid not to stir the soil any more than absolutely necessary". Their scraped plots produced on an average 99.1% as much corn as did the cultivated plots. The experimental designs of the earlier experiments described above were incomplete since they did not consider soil structure. The designs confounded weed control and
