Clay minerals are silicate minerals which form very small platy crystals, between the layers of which water can be absorbed Clay as a sedimentary rock is an accumulation of clay minerals to form a thick sticky deposit For clay minerals to be deposited from water, the water must be nearly still, and therefore clays often represent very quiet marine, lake or river backwater environments
As a soil separate, the mineral soil particles less than 0 002 millimeter in diameter As a soil textural class, soil material that is 40 percent or more clay, less than 45 percent sand, and less than 40 percent silt
In tennis, matches played on clay are played on courts whose surface is covered with finely crushed stones or brick. He was a clay-court specialist who won Wimbledon five times. American abolitionist and public official who was minister to Russia (1861-1862 and 1863-1869). See Muhammad Ali. American politician who pushed the Missouri Compromise through the U.S. House of Representatives (1820) in an effort to reconcile free and slave states. American army officer who commanded U.S. forces in Germany (1945-1949) and oversaw the Berlin airlift (1948). a type of heavy sticky earth that can be used for making pots, bricks etc feet of clay foot (27). Soil particles with diameters less than
A natural earthy material, plastic when wet, that is used for pottery or modelling
(1) Substrate particles that are smaller than silt and generally less than 0 003 mm in diameter (2) A soil textural class containing > 40% clay, < 45% sand, and < 40 % silt
Mineral particle with a size less than 0 004 millimeters in diameter Also see silt and sand
A very fine grained material, smaller than silt (clay has a diameter of less than 1/256 mm) Clay is formed by the weathering and breaking down of rocks and minerals
An earthy material that is plastic when moist but hard when fired, composed mainly of extremely fine plate-like mineral particles
A mineral soil separate consisting of particles <0 002 mm diameter Clayey soils have the highest water retention capacity relative to sandy or loamy soils
First read the entry on cations Ok Because clay is attracting cations, fertilizers (which are comprised of many minerals that will readily form cations in solution) will become "attached" to the clay, rather than be left available for the plant they were intended for To prevent this, lime can be added to the soil ahead of time The lime releases a preliminary batch of cations that will effectively neutralize most of the clay and thereby allow fertilizers to reach plants Clay particles are the smallest inorganic component of soil, measuring no more that 002 mm across In a soil heavy in clay, water and air will have trouble penetrating and reaching soil organisms and plants Break up clay soils by adding organic material
{i} type of soil used to make pottery and bricks, soil which contains high percentage of silicates of aluminum
A size fraction less than 0 002mm in equivalent diameter Using the UK classification a clay soil contains 35% or more clay and less than 45% sand and less than 45% silt (of course the total components would not exceed 100%)
Fine-grained soil or the fine-grained portion of soil that can be made to exhibit plasticity (putty-like properties) within a range of moisture contents, and that exhibits considerable strength when air-dry Plastic soil which passes a No 200 (0 075 mm) United States Standard sieve Reclamation geologists have identified some clays in the various foundations of the Horsetooth dams
A sediment composed of extremely small grains less than four thousandths of a millimetre across
It is the result of the wearing down and decomposition, in part, of rocks containing aluminous minerals, as granite
