From Introduction: "Figure 1 shows the location of sources that have been either exploited or seriously considered at one time or another, super-imposed upon a map indicating by small letters the order of consumption of K2O in the leading States; the amount used in these States, together with the percentage of the total consumption of potash used as fertilizer in the United States in 1939, is given in table 1. Figure 2 shows the domestic production and total consumption of potassium salts, in terms of tons of K2O, with the value per unit at the plants, for each year since 1913. Considered together, these two figures tell a significant story."

The Midwestern Disaster Tax Relief Act of 2008 is intended to assist with the recovery from the severe weather that affected the Midwest during the summer of 2008. The Jobs, Energy, Families, and Disaster Relief Act of 2008 includes some similar provisions, but these are not limited to the Midwest disaster. The disaster relief in the three bills is similar to that provided to assist with the recovery from the 2005 hurricanes and the 2007 Kansas tornadoes. This report broadly discusses the disaster relief provisions in other relevant legislation.
