A good job of breaking is shown in figure 5. Where the land was continuously cropped, the plowing was done in the spring and a good seed bed prepared before sowing. The fallow ground was usually plowed in June or July, after weeds and. Fig. 5.—Sod land in the Judith Basin broken with a moldboard plow.

Plowing was done with a disk plow to a depth of 7 to 8 inches. It was found that if the land was worked down smooth after plowing there was likely to be considerable blowing of the soil during the winter; consequently, it has been the custom to leave the land rough until spring, when it is worked down with the disk and spike-tooth harrows to form a good seed bed. In the preparation of the land an effort has been made to follow actual farm practices as closely as possible. In some cases it has been necessary to do some cultivating and hand weeding in order to keep the land uniform, but on the whole the plats have not received any more cultivation than would be given under good farming Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
