5. The implications of preferential flow of solutes along macropores for environmental quality are extremely important. Some standard soil physical and chemical concepts need modification. Concepts of “immobile” or “dead” water, that does not significantly participate in flow processes, have already been used. However, the same principle should apply to the capacity of soils to adsorb cations. ” REFERENCES Addiscott, T. M. 1977. A simplecomputer model for leachinginstructuredsoils. J.

The percolatingwater can be replaced by a solution of, for example, CaCl,, and the chloride concentration in the column effluent can be monitored as a function of time to obtain a measure for the range of flow velocities within the sample. Chlorides are used because they are not adsorbed by the soil particles. If the maximum and minimum velocities are both close to the average velocity (for example, in a sand) we will find a relatively long period INFLUENCE OF SOIL MACROPOROSITY 19 A lllll B 11111 C Dlll CICO 0 8- 0 6- Breakthrough curves 04 1 7 displacing liquid = displaced liquid 02 0 10 2 0 VIVO Fig.
