Soil Moisture | Drought.gov
WEBJun 8, 2021 · Soil moisture—sometimes also called soil water—represents the water in land surfaces that is not in rivers, lakes, or groundwater, but instead resides in the pores of the soil. The level of soil moisture is determined by a host of factors beyond weather conditions, including soil type and associated vegetation.
Soil Moisture - an overview | ScienceDirect Topics
WEBSoil moisture is the amount of water in the active layer of the soil, typically the top 1–2 m. It is extremely important because it is the main source of water for agriculture and natural vegetation.
Soil moisture - Wikipedia
WEBSoil moisture is the water content of the soil. It can be expressed in terms of volume or weight. Soil moisture measurement can be based on in situ probes (e.g., capacitance probes, neutron probes) or remote sensing methods. Water that enters a field is removed from a field by runoff, drainage, evaporation or transpiration.
What is soil moisture? The science behind the measurement
WEBWhat is soil moisture? Below is a comprehensive look at the definition of soil moisture and an exploration of some important scientific terms used in conjunction with soil moisture. What does soil moisture even mean? Soil moisture is more than just knowing the amount of water in soil.
Soil Moisture: Methods Of Measuring & Tools For Monitoring
WEBSep 20, 2022 · What Is Soil Moisture? This term refers to the entire quantity of water in the ground’s pores or on its surface. The moisture content of soil depends on such factors as weather, type of land, and plants. Why Is Soil Moisture Important For Agriculture.
Soil Moisture 101: What It Means and How It’s Measured
WEBFeb 22, 2022 · Why do we measure soil moisture? Measuring soil moisture is useful for agricultural management (e.g., effective irrigation), basin management, wildfire risk assessment, etc. 12:01.

NASA-USDA Global Soil Moisture Data | Earth
WEBMay 8, 2024 · The NASA-USDA Global soil moisture data provides soil moisture information across the globe at 0.25°x0.25°spatial resolution. These data sets include: surface and subsurface soil moisture (mm), soil moisture profile (%), surface and subsurface soil moisture anomalies (-).
Measuring Soil Moisture - Center for Agriculture, Food, and the …
WEBSoil water potential or soil moisture tension is a measurement of how tightly water clings to the soil and is expressed in units of pressure called bars (one bar is equal in strength to the pressure of one atmosphere). Generally the drier the soil, the greater the soil water potential and the harder a plant must work to draw water from the soil.
