The Great Plains region is a semi arid region. That means that it has relatively low amount of precipitation. Also, the precipitation occurs only in certain parts of the year, and there's relatively long droughts in between. This has led to the Great Plains region to naturally be a grassland. The grasses have contributed with their quick decomposition for a very fertile soil with deep top humus layer. In order to use the soil, the climate conditions, as well as to retain the soil's high productivity, the farmers have mainly orientated towards the farming of crops like the wheat and the oats. They do not require a lot of water, have characteristics that make them suitable for the climate, and their roots and leftovers from the steams are decomposing very quickly which retains the soil's fertility.
