Measuring the saturated hydraulic conductivity of peat substrates in nursery containers

摘要: Pore size, distribution and continuity are important characteristics for the exchange storage of air water in artificial mixes. Saturated hydraulic conductivity (Ks) measurements can be used to obtain such a characterization. However, two difficulties encountered when using Ks potting media. First, validity may limited because it not apply media composed coarse material or peat. Second, structure peat substrates is very sensitive situ potted (i.e. made directly pots) should carried out avoid any disruptive effect due handling. Such measurement, pots, require evaluation flux reduction resulting from container outflow configuration. The objectives this study were therefore check Darcy’s law propose an approach estimating saturated flow nursery container...
