Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.

No-till farming improves water retention: crop residues help water from natural precipitation and irrigation to infiltrate the soil. Residue limits evaporation , conserving water. Evaporation from tilling increases the amount of water by around 1/3 to 3/4 inches (0.85 to 1.9 cm) per pass.
In laboratory experiments, bioretention cells removed 94%, 88%, 95%, and >95% of zinc, copper, lead, and cadmium, respectively from water with metal concentrations typical of stormwater runoff. While this is a great benefit for water quality improvement, bioretention systems have a finite capacity for heavy metal removal.
The first rain gardens were created to mimic the natural water retention areas that developed before urbanization occurred. The rain gardens for residential use were developed in 1990 in Prince George's County, Maryland, when Dick Brinker, a developer building a new housing subdivision had the idea to replace the traditional best management practices (BMP) pond with a bioretention area.
Maltodextrin is used to improve the texture and mouthfeel of food and beverage products, such as potato chips and "light" peanut butter to reduce the fat content. [6] It is an effective flavorant, bulking agent, and sugar substitute. [6] Maltodextrin is easily digestible and can provide a quick source of food energy. [6]
[20] [22] Once the available water is used up the remaining moisture is called unavailable water as the plant cannot produce sufficient suction to draw that water in. Wilting point The wilting point is the minimum amount of water plants need to not wilt and approximates the boundary between available and unavailable water.
Water weight, also known as water retention, is a buildup of excess water or fluid in the body's tissues, which can occur for a variety of reasons, Dr. Felice Schnoll-Sussman, gastroenterologist ...
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.
