WebThe water content in the soil at saturation is equal to the percent porosity. Field capacity is the soil water content after the soil has been saturated and allowed to drain freely for … Used in geology, hydrogeology, soil science, and building science, the porosity of a porous medium (such as rock or sediment) describes the fraction of void space in the material, where the void may contain, for example, air or water. It is defined by the ratio: where VV is the volume of void-space (such as fluids) and VT is the total or bul…

WebJun 25, 2024 · 5.5: Porosity. Porosity (percentage of total pore space) is the volume of the soil occupied by pores. Where %P is percent porosity; Vp is volume of pores; Vt is volume total (solids plus pores). The total volume of pores is usually greater in a well-structured fine-textured (clayey) soil than in a coarse-textured (sandy) soil. WebV = bulk volume of soil (total soil volume) Porosity in soils varies between 0.3 (sands, silts) to 0.45 (clays) to 0.7 (peat), and is largely determined by the soil bulk density: air water …
