GEOLOGY

Detailed explanation-1: -The maximum amount of water that a given soil can retain is called field capacity, whereas a soil so dry that plants cannot liberate the remaining moisture from the soil particles is said to be at wilting point.

Detailed explanation-2: -“Soil porosity” refers to the amount of pores, or open space, between soil particles. Pore spaces may be formed due to the movement of roots, worms, and insects; expanding gases trapped within these spaces by groundwater; and/or the dissolution of the soil parent material. Soil texture can also affect soil porosity.

Detailed explanation-3: -Total porosity is the percent of the soil volume occupied by pore spaces, water-holding capacity is the percent of the soil volume that contains water, and air-filled porosity is the percent of the soil volume that is filled with air. These parameters can be measured for any soil mix for a designated container size.

Detailed explanation-4: -The amount of water a material can hold is directly related to the porosity since water will try and fill the empty spaces in a material. We measure porosity by the percentage of empty space that exists within a particular porous media.
