Abstract
Field studies were conducted for three years (1987–1989) at two locations to evaluate 4 commercial triple superphosphate (TSP) fertilizers containing various levels of water-soluble P. The fertilizers had been produced from phosphate rock deposits located in Florida, North Carolina and Morocco. AOAC available P was 81 to 94% water-soluble. Water-soluble P was inversely related to the level of Fe and Al in the fertilizers. Phosphorus from each source was applied to a Malbis soil (Plinthic Paleudults) and a Hartsells soil (Typic Hapludults) at rates of 0, 25, 49 and 99 kg ha−1. Potato (Solanum tuberosum L.) yields were increased by the application of P, except for the Malbis soil in 1988. Yields were not affected by the source of added P on either soil during the three years of the study. Fertilizer performance was not affected by the level of water-soluble P or the content of Fe and Al when band applied to potatoes under field conditions in the Southeastern United States.
