ASTM C602 is the ASTM standard for Agricultural Liming Materials, giving buyers and technical teams a clear reference for evaluating products used to improve soil conditions. As a specification, it helps define the characteristics and expectations for these materials so they can be selected with greater confidence in procurement, testing, and quality control. For organizations that handle agricultural soil amendments, ASTM C602 supports more consistent product comparison and compliance-minded decision-making.

What is ASTM C602?

ASTM C602, Standard Specification for Agricultural Liming Materials, is a technical document intended to describe the requirements for liming materials used in agricultural applications. It serves as a common basis for identifying whether a product meets the expected specification for this material category. In practical terms, the standard is useful when reviewing product quality, comparing suppliers, or confirming that a liming material aligns with established ASTM requirements for use in agricultural settings.

Where is ASTM C602 used?

This standard is commonly used in agriculture-related procurement, laboratory evaluation, and quality assurance workflows for liming materials. It may be referenced by producers, distributors, testing labs, and purchasers who need a consistent way to specify or verify agricultural liming products. ASTM C602 is especially relevant wherever liming materials are selected, tested, or documented for soil treatment programs and related supply chains.

Why is ASTM C602 important?

ASTM C602 matters because it helps bring consistency to the evaluation and purchase of agricultural liming materials. A clear specification supports better product comparison, reduces ambiguity in contracts and testing, and can help lower the risk of receiving material that does not meet expectations. For stakeholders involved in compliance, quality control, or product acceptance, ASTM C602 provides a practical benchmark for decision-making and communication.
