Abstract
Abstract Soil solution P concentration was monitored at weekly intervals during the vegetative growth of Rice ( Oryza sativa L. var. ‘Bluebelle’) on flooded soils from the gulf coast region of Texas. Significant increases in dry matter production were obtained from application of phosphate fertilizer. Average soil solution P concentration ranged from 0.02 to 5.28 ppm when all soils and P fertilization rates were considered. A linear relationship was obtained between the logarithm of the average soil solution P concentration and the P concentration or P uptake of the plant. Yields were greater than 90% of maximum when the average soil solution P concentration was greater than 0.1 ppm. The concentration of P in the plant tissue at 0.1 ppm soil solution P was 0.25%.
