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.
Loam (the high-humus definition, not the soil texture definition) may be used for the construction of houses, for example in loam post and beam construction. [6] Building crews can build a layer of loam on the inside of walls, which can help to control air humidity. Loam, combined with straw, can be used as rough construction material to build ...

[1] Stagnogley soils are related to the pseudogleys and are classified as gleyic soils. The name "stagnogley" comes from the soil's gley dynamics.
The plant is normally grown in well-drained loamy soil, using rhizomes planted at the start of the rainy season. [22] In addition, new plants can be started by seeds. [ 25 ] Growers harvest abacá fields every three to eight months after an initial growth period of 12–25 months.
A fourth term, loam, is used to describe equal properties of sand, silt, and clay in a soil sample, and lends to the naming of even more classifications, e.g. "clay loam" or "silt loam". Determining soil texture is often aided with the use of a soil texture triangle plot. [5] An example of a soil triangle is found on the right side of the page.
A Psamment has no distinct soil horizons, and must consist entirely of material of loamy sand or coarser in texture. In the World Reference Base for Soil Resources (WRB), most Psamments belong to the Arenosols. However, Psamments of fluviatile, lacustrine or marine origin belong to the Fluvisols. Psamments cover 3.4% of the global land mass.
A typical Tifton soil profile consists of an 11 inches (280 mm) topsoil of dark grayish brown loamy sand.The subsoil extends to about 65 inches, strong brown fine sandy loam to 22 inches; yellowish brown sandy clay loam to 40 inches; yellowish brown mottled, sandy clay loam to 60 inches, and strong brown, mottled sandy clay to 65 inches.
The Philippines' Bureau of Soils and Water Management (Filipino: Kawanihan ng Pamamahala sa Lupa at Tubig, [1] abbreviated as BSWM), is an agency of the Philippine government under the Department of Agriculture responsible for advising and rendering assistance on matters relative to the utilization of soils and water as vital agricultural resources.
