Topsoil does not generally include soilfrom peatlands or other special areas, such as land disturbed byindustrial activity. Topsoil is usually a darker sha

19、de of brown,gray, or red than the subsoil that lies immediately beneath it,because it contains organic matter intimately mixed with themineral matter. Topsoil tends to be more friable and perviousthan inorganic soils.4. Significance and Use4.1 When physically evaluating a soil, relative to its suit-

20、ability to support plant growth (primarily grasses), tests mustbe performed to determine the presence and amount of solidmatter (organic and inorganic) compatibility that can determinepotential air-void content and water-holding ability, and finally,deleterious materials.4.2 Typical general ranges o

21、f soil content for suitabletopsoils are presented in Specification D 5268. It should berecognized, however, that in some geographic regions, concur-rence with the values in the referenced table would be difficult.In such situations, locally acceptable specifications need to bedeveloped.5. Function a

22、nd Material5.1 FunctionThe potential/success of a topsoil amend-ment is measured/determined by its ability to provide some orall of the desired properties/characteristics of the topsoil thatare absent in the unamended topsoil or soil. Soils consistessentially of three space-occupying components: wat

23、er, airvoids, and solid particulate matter. The third component can befurther divided into two sub-components: organic matter, suchas peat, muck or other decayed matter: and inorganic mineralmatter, such as clay, silt and sand. ESCS falls into the lattergroup of the third component sub-component gro

24、up, as a bettersubstitute for sand.5.2 MaterialESCS, is a rotary kiln produced vesicularamorphous silicate particulate material. It is a highly porous,low density material with an apparent specific gravity ofapproximately 0.8 to 2.4, and a dry/loose unit weight ofapproximately 35 to 70 lb/ft3, (561

25、to 1121 kg/m3). Thepre-sized raw shale, clay or slate used to produce ESCS is firedin the kiln at a temperature between 1800F (982C) and2200F (1205C). As it exits the kiln the material is sterile,inert, and ceramic. Some crushing may be performed tofacilitate final sizing in a screening system. ESCS

26、 in generallyneutral in pH although the pH can vary somewhat dependingon the raw material and the fuel in the kiln. Density, or looseunit weight, is determined by Test Method C 29/C 29M. Theabsorption may be determined by Test Method C 566 aftersoaking the sample a sufficient period of time, usually

27、 3 to 7days, depending on the source and the grading of the material.The particle distribution may be determined with appropriatesieves as stated in Specification E 11. The ESCS may besampled in accordance with Practice D 75.6. Application6.1 ESCS is generally used in horticultural topsoil applica-t

28、ions as a substitute for the sand sub-component of soils solidcomponent (see Specification D 5268, Table 1). The mainadjustment that needs to be made is a correction for the weightand volume relationship of ESCS fines, that is, the minus No.4 (4.75 mm) sieve size to a similar size of sand. The oven-

29、dryor saturated surface dry/loose unit weight tests (see TestMethod C 29/C 29M) can be performed to establish theweight-volume relationship. Typically, a loose cubic foot ofESCS fines will weigh approximately from 35 lb/ft3(560 kg/m3to 70 lb/ft3) (1120 kg/m3) depending on the source. Absorptionof ES

30、CS varies with the source, but is usually from approxi-mately 18 % to 35 % of the oven-dry loose unit weight. Severalblends of topsoil using ESCS with or in place of the sandshould be prepared and evaluated with regard to potential foraeration, moisture retention, resistance to compaction, and theot

It has beenused in horticultural research as well as in private and commercial plant(and grass) soil modification management in the United States and Europesince the early 1920s. It is used extensively i
