Sand separator

sand separator See separator.

sandstone Sedimentary rock composed of particles of sand with a high silica content bound in a natural cement. It is usually a relatively soft stone being easily eroded, but some are hard and durable. Some can even be polished.

sandy clay A soil textural class comprised of 35 to 55% clay, 0 to 20% silt, and 45 to 65% sand.

sandy clay loam A soil textural class comprised of 20 to 35% clay, 0 to 28% silt, and 40 to 80% sand.

sandy loam A soil textural class comprised of 0 to 20% clay, 15 to 50% silt, and 45 to 80% sand. Individual grains of sand can be felt and seen, but it has enough silt and clay to make it somewhat coherent. If it is squeezed while dry, it will form a cast that will fall apart readily. If squeezed while wet, it will form a cast that will fall apart unless handled carefully.

sanguineous A botanical term referring to a bloodred color.

sanitary sewer A pipe system conducting sewage, usually to a treatment facility.

sap The fluid flowing in the vascular tissue of plants.

sapling 1. A young tree. 2. A tree less than 4 in. in diameter at breast height.

saprophyte A plant that grows on dead or decaying organic matter.

sapwood Wood from the outer portions of a tree trunk between the bark and heartwood where there are active growth cells. It comprises the live cells of the xylem and phloem. It is generally more permeable, less durable, lighter in color, and less resistant to decay than heart-wood.

sarment A runner.

saturated soil Soil in which all pore spaces are filled with water.

saturation coefficient Refers to the saturation coefficient for brick, which is the ratio of the percent absorption of a brick submerged in cold water for 24 hours to the absorption of a brick submersed in boiling water over a 5-hour period. The 24-hour cold water test is divided by the 5-hour boiling test. This value is a strength value that assists in measuring the durability of mason units. Durability of mason units may also be measured by conducting freeze/thaw tests. This is of prime importance in landscape work (especially in temperate climates) as brick in the landscape is exposed on one or both sides in nearly all cases. Most brick in the landscape should have a compressive strength of 3000 psi with a 5-hour boiling absorption at 17% maximum, and a maximum average saturation coefficient of 0.78. However, if a brick's minimum compressive strength is 8000 psi or greater, or in the cold water test of 24 hours absorbs less than 8% water, the saturation coefficient can be ignored.

savanna, savannah 1. A treeless grassland or area of only low-growing plants. 2. A tropical ecosystem with a consistent herbaceous ground cover (grasses or drought-resistant low growth) and scattered trees. 3. A zone of transition between grasslands and forests, where there are scattered individual trees or clumps of trees and shrubs.

saw A cutting tool with a thin, flat blade, band, or stiff plate with cutting teeth or an abrasive that cuts as it slides through a material.

sawdust Fine, dusty wood shavings from cutting wood. This material is often used as a
