Abstract

This study is concerned with potential impacts of limited fertilizer supplies in the future. Limitations could come through either (a) high prices for fertilizer in competition with world food producers or alternative uses of anhydrous ammonia, or (b) government rationing of fertilizer, if this extreme were ever needed. Hence, the analysis is not concerned with the means by which the limitations in use are attained . It is concerned more with the impact of limited fertilizer availability and use on American agriculture. Hence, we suppose a limited amount of fertilizer is allocated over the regions and crops of the United Stat es . We wish to examine the implications of this allocation on interregional and regional shifts in crop production and land use. The method of allocation of available fertilizer is based on equating the marginal value productivities of fertilizer with the cost of the fertilizer in different producing regions.
