Modelling non-uniform soil water uptake by a single plant root

  title={Modelling non-uniform soil water uptake by a single plant root},
  author={Erkki Aura},
  journal={Plant and Soil},
The assumption of uniform water flow to the root or uniform water potential at the root surface was shown by Hainsworth and Aylmore (1986, 1989) to be erroneous. The present paper demonstrates how the non-uniform uptake of water by a single root can be modeled. Differential equations are numerically solved to describe simultaneous water movement in the plant and in the soil. In the plant, boundary conditions are the water potentials at the root surface (Ψs) and in the xylem at the root base (Ψb… CONTINUE READING
