Conteúdo: 	Soil and tissue samples were taken just prior to layby and at harvest of watermelon from fertilizer trials on Astatula fine sand, a typic Quartzipmment, near Leesburg in 1969 and 1970. Soil concentration of fertilizer nutrients sampled at the center of the bed at layby was higher when 75% of the fertilizer was applied preplant than when 50% was applied preplant but tissue composition at layby and at harvest was not affected by the timing of fertilizer application. Better recovery of fertilizer salt occurred when fertilizer was broadcast than when banded. Tissue K and Ca generally were higher when preplant fertilizer was broadcast and tissue P tended to be higher when preplant fertilizer was banded. Tissue N, P, and K tended to be higher when higherrates of the respective nutrients were applied. An antagonistic effect of soil K on plant absorption of Ca and Mg was found.
