(Test Method)Standard Test Method for Determination of Rolled Erosion Control Product (RECP) Ability to Encourage Seed Germination and Plant Growth Under Bench-Scale Conditions
Standard Test Method for Determination of Rolled Erosion Control Product (RECP) Ability to Encourage Seed Germination and Plant Growth Under Bench-Scale Conditions
SIGNIFICANCE AND USE
5.1 This test method evaluates the effect of an RECP on seed germination and initial plant growth in a controlled environment.
5.2 The results of this test can be used to compare RECPs and other erosion control materials to determine which are the most effective at encouraging the growth of vegetation.
SCOPE
1.1 This test method covers guidelines, requirements, and procedures for evaluating the effect of Rolled Erosion Control Products (RECPs) on seed germination and vegetation enhancement.
1.2 This test method will evaluate the effects of RECPs on seed germination in a controlled environment.
1.3 This test method utilizes bench-scale testing procedures and shall not be interpreted as indicative of field performance.
1.4 This test method is not intended to replace full-scale simulation or field testing in acquisition of performance values that are required in the design of erosion control measures utilizing RECPs.
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4. Summary of Test Method
4.1 Containers containing soil are sown with seeds and then covered with an RECP. Additional containers of soil are sown with
seed and left uncovered as controls. The light, temperature, and humidity are maintained and documented. The amount of
germination and growth is measured periodically throughout the test, and the mass of vegetation is calculated at the conclusion
of the test.
4.2 Each RECP under consideration as well as control containers of uncovered soil undergo testing in a controlled environment.
