The estimated world’s potash production between the period 1970–1991 is listed in Table 9–1. Many of the individual country estimates must be considered as quite uncertain because of the lack of detailed reporting data, or perhaps due to being inflated for political reasons. However, the general trends are probably quite valid. Figure 9–1 shows a plot of this production from 1962–1991, indicating a rapid increase through the 1960’s to the mid-1970’s, and then very slow continued growth. With the break-up of the Iron Curtain countries the Eastern Block consumption and production has dropped dramatically, and a simultaneous general worldwide recession has caused a reduction in production from 1988–1993. The annual growth rate had been 5.7% from 1962–1978, and 2% from 1978–1988. For the entire period 1962–1991 the average increase in production was 3.1%/yr. Prior to the first period most of the world’s potash came from Germany, France, or United States plants, and there was not a large export movement. However, during the 1960’s and early 1970’s the very large Canadian and Russian mines opened, and they developed extensive new markets. Russia and the Eastern Block became essentially the total consumers of the greatly increased supply of USSR and East German potash. The new Canadian mines largely developed the Asian and (with others) the Brazilian markets, thus utilizing much of their capacity.
