Wheat Production and Marketing. 105 DIFFERENCES IN THE CHOICE OF CROPS BETWEENCENTRAL IOWA AND NORTHEASTERN NORTH DAKOTA AS SHOWN BY ACREAGES OF 1919. Fig. 31.—In a cross section of the spring-wheat belt, northwestward fromnorth central Iowa to northeastern North Dakota, the proportion of wheatrapidly increases, largely replacing corn, which almost vanishes because ofincreasing climatic handicaps. The proportion of oats and tame hay slowlydecreases, and the proportion of other small grain, principally barley andflax, increases. There are many other factors which govern the propor-tionate acreage of different crops in any given section ( and 32). One of the most important factors is the eco-nomical distribution of labor on the farm throughout theyear. In considering competition between crops for land,therefore, we must not overlook the fact that the farmer inadjusting his business weighs the different possible uses andrequirements of labor (man labor) and equipment (horses,cattle, machinery, fences, etc.) with the different possibleuses and requirements of land. Thus, even though he issituated where wheat is the one single c
