The method of measuring saturated soil hydraulic conductivity by using permeating bucket is easy and simple and the instrument is cheap. The water volume must be measuring for many times, meanwhile the water must be added on the top of permeating bucket to sustain the water layer thickness. Based on the principles of supplying water in the fixed water head by Marriott bottle, the method mentioned above is improved, which can reduce the experiment work and improve the experiment accuracy.

The method of Libardi to estimate soil hydraulic conductivity in the field, during the redistribution of soil water, is discussed and improved. It is shown that if the saturated soil water content is measured at the soil surface, values at any other depth can be calculated from the database used to compute hydraulic conductivity. Since the saturated soil water content is difficult to measure and critical to the establishment of the hydraulic conductivity functions, this is an important refinement of the method. It is also shown that the unit hydraulic gradient assumption, which is part of the methodology, does not introduce significant errors in the estimation of soil hydraulic conductivity.
