Hi Wanita: The soil fertility pattern of the United States was determined by two main climatic factors, rain and temperature, according to the soil scientist, Albrecht. Rainfall first constructs soil fertility but it also eventually destructs soil fertility. As you go from east to west in the USA, annual rainfall declines across much of the country. Thus, as Albrecht explains, the soils in the east were the most highly weathered by rainfall, while soils west of where the buffalo roamed received too little rainfall for soil construction, much less soil destruction. Heat makes matters worse in soil destruction, so the south east area of the USA had the worst soil, not New England. Albrecht reports how this soil fertility pattern was reflected in the health of potential draftees in WWII, at a time when more food was still produced and eaten locally. The tooth decay rate of potentail draftees of and the rate of acceptance of draftees into the army were consistent with this soil fertility pattern of the USA. More potential draftees were suitable for service in the states with higher soil fertility, and the highest rejection rate of 70% was in a south eastern state. By the way, the best soils, as Albrecht reports, were where the bison roamed. They were only found in two areas in the eastern US.
