Water content — Soil composition by phase: s soil (dry), v void (pores filled with water or air), w water, a air. V is volume, M is mass. Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture),… … Wikipedia
water content — The amount of water lost from the soil after drying it to constant weight at 105NC, expressed either as the weight of water per unit weight of dry soil or as the volume of water per unit bulk volume of soil [22]. See moisture content … Lexicon of Cave and Karst Terminology
Optimum water content for tillage — The optimum water content for tillage (OPT) is defined as the moisture content of soil at which tillage produces the largest number of small aggregates. Contents 1 Overview 2 Relationships between water content at field capacity (FC) and Plastic… … Wikipedia
Soil moisture sensors — measure the water content in soil. A soil moisture probe is made up of multiple soil moisture sensors. One common type of soil moisture sensors in commercial use include the Frequency domain sensor such as the capacitance sensor. One of the major … Wikipedia
Water retention curve — is the relationship between the water content, θ, and the soil water potential, ψ. This 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… … Wikipedia
Soil carbon — is the generic name for carbon held within the soil, primarily in association with its organic content. This discussion begins with a brief introduction to soil carbon, its function within the soil, influences on soil carbon, and finally the… … Wikipedia
Soil liquefaction — describes the behavior of loose saturated unconsolidated soils, i.e. loose sands, which go from a solid state to have the consistency of a heavy liquid, or reach a liquefied state as a consequence of increasing porewater pressures, and thus… … Wikipedia
Water absorption — is a phenomenon in the transmission of electromagnetic radiation through a medium containing water molecules. Water molecules are excited by radiation at certain wavelengths and tend to selectively absorb portions of the spectrum while allowing… … Wikipedia
Soil physics — is the study of soil physical properties and processes. It is applied to management and prediction under natural and managed ecosystems. Soil physics deals with the dynamics of physical soil components and their phases as solids, liquids, and… … Wikipedia
Water activity — or aw is a measurement of the energy status of the water in a system. It is defined as the vapor pressure of water above a sample divided by that of pure water at the same temperature; therefore, pure distilled water has a water activity of… … Wikipedia
