The fraction of water held back in the aquifer is known as specific retention. Thus it can be said that porosity is the sum of specific yield and specific retention. Specific yield of soils differ from each other in the sense that some soil types have strong molecular attraction with the water held in their pores while others have less.
Available water is that which the plants can utilize from the soil within the range between field capacity and wilting point. Roughly speaking for agriculture (top layer soil), soil is 25% water, 25% air, 45% mineral, 5% other; water varies widely from about 1% to 90% due to several retention and drainage properties of a given soil.
Specific yield, also known as the drainable porosity, is a ratio, less than or equal to the effective porosity, indicating the volumetric fraction of the bulk aquifer volume that a given aquifer will yield when all the water is allowed to drain out of it under the forces of gravity:
Water retention can refer to: Water retention (medicine), an abnormal accumulation of fluid in the circulatory system or within the tissues or cavities of the body Edema, an abnormal accumulation of fluid beneath the skin, or in one or more cavities of the body; Premenstrual water retention, a common phenomenon associated with the menstrual cycle
If you drink regularly and notice symptoms of water retention, try cutting back or taking a break, says Badgett. Eat hydrating foods. Another way to up your water intake is to eat more hydrating ...
Water retention curve is the relationship between the water content, θ, and the soil water potential, ψ. The soil moisture curve is characteristic for different types of soil, and is also called the soil moisture characteristic. It is used to predict the soil water storage, water supply to the plants (field capacity) and soil aggregate stability.
His efforts have inspired other U.S. ranchers to pelletize their waste wool, and he landed his $13.98 eight-ounce bags of Wild Valley Farms Wool Pellets on Amazon in 2016 and on Lowes.com in 2023.
The nominal definition of field capacity (expressed symbolically as θ fc) is the bulk water content retained in soil at −33 kPa (or −0.33 bar) of hydraulic head or suction pressure. The term originated from Israelsen and West [1] and Frank Veihmeyer and Arthur Hendrickson. [2]
