But if there should be no fall nor spring rains, as is often the case in the semi-arid west, there will be little packing done by nature. It is better, there- fore, to use the subsurface packer on fall plowing than to take any chances on nature doing the work. On spring plowing, however, when a crop is to be planted immediately, the sub- surface packer should never be omitted. It should follow the plow, and the deeper the plowing the greater the necessity for packing. Prevents Soil Drifting The... fact that subsurface packing will prevent to a large extent soil drifting is pretty well established. The scientific principles involved are not clearly understood, but it is believed that a well packed soil, possessing as it does a high degree of capillarity up to within a few inches of the surface, retains its vitality longer and imparts that virile condition even to the surface mulch. Whatever be the reason, the universal experience from North Dakota to Texas has been that, while fields handled by the ordinary methods and unpacked were blown out of their fences, the subpacked field remained unin- jured.
