These properties are storativity (S), specific storage (S s) and specific yield (S y). According to Groundwater, by Freeze and Cherry (1979), specific storage, [m −1], of a saturated aquifer is defined as the volume of water that a unit volume of the aquifer releases from storage under a unit decline in hydraulic head.

Burial of food can preserve it due to a variety of factors: lack of light, lack of oxygen, cool temperatures, pH level, or desiccants in the soil. Burial may be combined with other methods such as salting or fermentation. Most foods can be preserved in soil that is very dry and salty (thus a desiccant) such as sand, or soil that is frozen.
The presence of mucilage in seeds affects important ecological processes in some plant species, such as tolerance of water stress, competition via allelopathy, or facilitation of germination through attachment to soil particles. [13] [14] [15] Some authors have also suggested a role of seed mucilage in protecting DNA material from irradiation ...
The root microbiome (also called rhizosphere microbiome) is the dynamic community of microorganisms associated with plant roots. [1] Because they are rich in a variety of carbon compounds, plant roots provide unique environments for a diverse assemblage of soil microorganisms, including bacteria, fungi, and archaea.
The specific heat of soil increases as water content increases, since the heat capacity of water is greater than that of dry soil. [89] The specific heat of pure water is ~ 1 calorie per gram, the specific heat of dry soil is ~ 0.2 calories per gram, hence, the specific heat of wet soil is ~ 0.2 to 1 calories per gram (0.8 to 4.2 kJ per ...
However, germination problems have reportedly hindered the use of these cultivars thus far. This may be due to phytic acid's critical role in both phosphorus and metal ion storage. [9] Phytate variants also have the potential to be used in soil remediation, to immobilize uranium, nickel, and other inorganic contaminants. [10]
Powdered milk (or milk powder), produced by removing the water from (usually skim) milk; Khoa, milk which has been completely concentrated by evaporation, used in Indian cuisine; Infant formula, dried milk powder with specific additives for feeding human infants; High milk-fat and nutritional products (for infant formulas)
Once in the soil-plant system, most nutrients are recycled through living organisms, plant and microbial residues (soil organic matter), mineral-bound forms, and the soil solution. Both living soil organisms (microbes, animals and plant roots) and soil organic matter are of critical importance to this recycling, and thereby to soil formation ...
