ASTM D6836 - 16

Overview

ASTM D6836 - 16 outlines standard test methods for determining the soil water characteristic curve for desorption. This standard is essential for professionals in environmental science, soil science, and agricultural engineering, as it provides a reliable framework for understanding soil moisture dynamics. The methods described in this standard include the use of hanging columns, pressure extractors, chilled mirror hygrometers, and centrifuges.

Key Requirements

The standard specifies the procedures and equipment necessary for accurately measuring the soil water characteristic curve. Key requirements include:

• Equipment Calibration: All instruments must be calibrated according to the manufacturer's specifications to ensure accuracy.
• Sample Preparation: Soil samples must be representative and prepared according to specified protocols to avoid bias in results.
• Data Collection: Measurements must be taken at consistent intervals to capture the full range of soil moisture conditions.
• Reporting: Results must be documented in a clear and concise manner, including all relevant parameters and conditions.

Implementation Benefits

Implementing ASTM D6836 - 16 provides several benefits for compliance professionals and organisations involved in environmental and health protection:

• Improved Soil Management: Understanding soil water characteristics aids in effective soil management practices, enhancing agricultural productivity and sustainability.
• Enhanced Water Resource Management: Accurate data on soil moisture can inform irrigation practices, leading to more efficient water use.
• Regulatory Compliance: Adhering to this standard helps organisations meet environmental regulations and standards, reducing the risk of non-compliance penalties.
• Research and Development: The standard supports research initiatives aimed at improving soil and water conservation techniques.

Compliance Value

Compliance with ASTM D6836 - 16 is crucial for organisations seeking to demonstrate their commitment to environmental stewardship. By following the guidelines set forth in this standard, organisations can:

• Ensure Data Integrity: Reliable data collection methods enhance the credibility of research and reporting.
• Facilitate Environmental Assessments: Accurate soil moisture data is essential for environmental impact assessments and land use planning.
• Support Sustainable Practices: The standard promotes practices that contribute to sustainable land management and conservation efforts.

In conclusion, ASTM D6836 - 16 provides a comprehensive framework for determining the soil water characteristic curve for desorption. Its implementation is vital for professionals aiming to enhance soil management practices, comply with environmental regulations, and contribute to sustainable resource management.
