A mathematical description of a pump/leak/buffer model for plant nitrate uptake

  • R. A. Sutherland
Short Communications


A pump/leak/buffer model of nitrate in plants is presented in the form of a differential equation, based on the computer simulation model of Scaife (1989). The equation is solved, and the long-term behaviour of the rate of nitrate uptake of the plants described.
