2、ation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers the material

3、characteristics, physicalrequirements, and sampling appropriate for the designation ofthe material as a mineral amendment.1.2 The presence in the topsoil of the correct nutrient andpH level is necessary for healthy plant growth. This guide doesnot, however, cover a determination of the nutrients, no

Nutrient defi-ciencies may be corrected by using fertilizers. Excess soluble salts shouldbe examined as to their desirability. The acidity or alkalinity

5、of the soil isalso important. Excess acidity may be corrected by the application of limedust. Excess alkalinity may be corrected by the application of sulfur orother suitable acidifying compounds. The latter item, in addition tolowering pH, also could be considered as an aggregate when consideringth

The values given in parentheses are for informationonly.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of t

Topsoil does not generally include soilfrom

19、 peatlands or other special areas, such as land disturbed byindustrial activity. Topsoil is usually a darker shade 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

20、perviousthan inorganic soils.4. Significance and Use4.1 When physically evaluating a soil, relative to its suit-ability to support plant growth (primarily grasses), tests mustbe performed to determine the presence and amount of solidmatter (organic and inorganic) compatibility that can determinepote

21、ntial air-void content and water-holding ability, and finally,deleterious materials.4.2 Typical general ranges of 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

22、table would be difficult.In such situations, locally acceptable specifications need to bedeveloped.5. Function and 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 th

23、atare absent in the unamended topsoil or soil. Soils consistessentially of three space-occupying components: water, 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 mine

24、ralmatter, such as clay, silt and sand. ESCS falls into the lattergroup of the third component sub-component group, 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

25、 specific gravity ofapproximately 0.8 to 2.4, and a dry/loose unit weight ofapproximately 35 to 70 lb/ft3, (561 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

26、sterile,inert, and ceramic. Some crushing may be performed tofacilitate final sizing in a screening system. ESCS 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. T

27、heabsorption may be determined by Test Method C 566 aftersoaking the sample a sufficient period of time, usually 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 E11. The ESCS may besampl

28、ed in accordance with Practice D75.6. Application6.1 ESCS is generally used in horticultural topsoil applica-tions 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

29、 relationship of ESCS fines, that is, the minus No.4 (4.75 mm) sieve size to a similar size of sand. The oven-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 w

30、eigh approximately from 35 lb/ft3(560 kg/m3to 70 lb/ft3) (1120 kg/m3) depending on the source. Absorptionof ESCS 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 prepar

31、ed and evaluated with regard to potential foraeration, moisture retention, resistance to compaction, and theother items covered in Specification D 5268.NOTE 2ESCS was originally patented as Haydite in 1918. It has beenused in horticultural research as well as in private and commercial plant(and gras
