N2 - Rhodes grass (Chloris gayana Kunth) plants were grown on various soil types in order to study the relationships between the available and hardly available soil P fractions. Results Indicate that when plants are grown Intensively in soils for long periods without additional P fertilization, recharge rate of the available fraction of soil P becomes a limiting factor. An approach to determine the recharge rate, using data on plant uptake and changes in sodium bicarbonate extractable soil P content are suggested.
