An Analytical Solution to Solute Transport Near Root Surfaces for Low Initial Concentration: II. Applications¹

ABSTRACT

Examples are presented to illustrate the affects of changing the outer radius (r₁), and the ratio of root absorbing power to inward flux of water (k/v_o) on nondimensional concentration as a function of nondimensional time and distance. The examples presented are based on the analytical solution to two flow situations (see Part I). A method is also presented to show how simple solutions can be constructed for the flow problem involving only trigonometric functions.
