Standard Test Methods for Organic Matter Content of Athletic Field Rootzone Mixes

Fecha:
2018-11-28 /Active
Abstract:

These test methods establish the apparatuses required, and standard calculations and procedures executed for quantifying the percent organic matter of volume ratio mixed putting green and sports turf root zone mixtures (except peat and other organic soils). Method A is performed by determining the loss on ignition (LOI). Method B or the Walkley Black method, on the other hand, is performed by a dichromate oxidation procedure whereby the color intensity of the reaction product is determined colorimetrically.

Scope:

1.1 These test methods cover the determination of the percent organic matter of a putting green root zone mixture using a loss on ignition method or the Walkley Black method. These test methods are useful for quantifying the organic matter content of volume ratio mixed root zone mixes. Test Methods D2974 is recommended for peat and other organic soils.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use, nor the disposal of hazardous waste that may be generated. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific precautionary statement, see 8.2.6.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
