Loam porosity
Witryna21 wrz 2024 · Sandy loams have larger pores than pure sand. On the other end of the spectrum, sandy soils drain well and have fairly decent porosity, even though the spaces between the particles are small. The garden soils with the best porosity are loamy soils, which are mixtures of clay, silt and sand with organic matter. 00:00 00:00. WitrynaPorosity change is a common characteristic of natural soils in fluid-solid interaction problems, which can lead to an obvious change of the soil-water retention curve (SWRC). The influence of porosity on soil water retention phenomena is investigated by a theoretical model and an experimental test in this study. A model expressing the …
