The hydrostatic root hydraulic conductivity
([k.sub.root]) was determined by measuring the steady state flow at four pressures (0.1; 0.2; 0.3; and 0.4 MPa).
Penetration resistance (PR) for 0.1--0.2 m and 0.2--0.3 m depth, gravimetric moisture (GM) for all depths, TP for 0.1--0.2 m and 0.2--0.3 m depth, and hydraulic conductivity
(K0) all had moderate variability.
For this purpose, some experiments are conducted to study the behavior of the hydraulic conductivity
of a sand-clay mixture.
macro-pores and hydraulic conductivity
) using physical amendments for facilitating salt leaching and thus creating a better condition for establishing salt-tolerant plants (halophytes), which can be used as fodder for livestock.
Effect of conservation agriculture on water holding capacity (WHC), hydraulic conductivity
(Kfs) and matric flux potential (Im) of soil in 0-15 cm depth under rice-wheat cropping.
In this study, the hydraulic conductivity
tests were performed after drying and wetting of samples to a range of matric suctions between 1 and 60 kPa.
of compacted kaolin-sand specimens under high hydraulic gradients.
where [K.sub.s] is the saturated hydraulic conductivity
. [K.sub.r] (h) is the relative hydraulic conductivity
and it is a function of the pressure head which makes the Richards equation highly nonlinear.
Because of the physical characteristics of this soil, it could be said that the flow is applied in piston flow and the other hypotheses suggested by Green-Ampt, so the decrease in the quality of performance from the models is attributed to the use of an altered sample of soil, which could not be the most advisable way to estimate the hydraulic conductivity
at saturation in the laboratory for soils with high contents of organic matter, and to the use of equations and a database that also do not contemplate soils with high contents of organic matter.
Benson and Boutwell  investigated compaction conditions and scale dependent hydraulic conductivity
of compacted clay liners.
Cline, "Effect of soil properties on unsaturated hydraulic conductivity
pore- interaction factors," Soil Science Society of America Journal, vol.
All of the studies cited indicated that the negative impacts of K and Mg on the saturated soil hydraulic conductivity
place them between the extremes of Na as the worst soil dispersant and calcium (Ca) as the best soil flocculant: Na > K > Mg > Ca.
