  2. Field capacity - Wikipedia

    en.wikipedia.org/wiki/Field_capacity

    Field capacity is characterized by measuring water content after wetting a soil profile, covering it (to prevent evaporation), and monitoring the change soil moisture in the profile. A relatively low rate of change indicates when macropore drainage ceases, which is called Field Capacity; it is also termed drained upper limit (DUL).

  3. Water retention curve - Wikipedia

    en.wikipedia.org/wiki/Water_retention_curve

    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.

  4. Available water capacity - Wikipedia

    en.wikipedia.org/wiki/Available_water_capacity

    Available water capacity is the amount of water that can be stored in a soil profile and be available for growing crops. [1] It is also known as available water content ( AWC ), profile available water ( PAW ) [ 2 ] or total available water ( TAW ).

  5. Soil water retention capacity - Wikipedia

    en.wikipedia.org/wiki/Soil_water_(retention)

    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.

    Our native soils locally are mostly pH 7.5 and higher, which means we should avoid large trees (East Texas pines, pin oaks, sweet gums, etc.) that require copious amounts of iron.

  7. Specific storage - Wikipedia

    Summary of hydrologic and physical properties of rock and soil materials as analyzed by the Hydrologic Laboratory of the U.S. Geological Survey 1948-1960. U.S. Geological Survey Water Supply Paper 1839-D. 42 p. De Wiest, R. J. (1966). On the storage coefficient and the equations of groundwater flow.

  8. Doctors Say This Nighttime Behavior Can Be A Sign Of Dementia

    Here's how to distinguish "sundowning"—agitation or confusion later in the day in dementia patients—from typical aging, from doctors who treat older adults.

  9. Soil thermal properties - Wikipedia

    en.wikipedia.org/wiki/Soil_thermal_properties

    Apart from the basic soil composition, which is constant at one location, soil thermal properties are strongly influenced by the soil volumetric water content, volume fraction of solids and volume fraction of air. Air is a poor thermal conductor and reduces the effectiveness of the solid and liquid phases to conduct heat.
