Summary

This foundational paper by Schollenberger and Simon describes and validates the ammonium acetate method for determining soil cation exchange capacity and exchangeable bases—a technique that became widely adopted in soil science laboratories. The method provides a standardised approach to quantifying the soil's ability to hold and exchange nutrient cations, essential information for soil fertility assessment and agronomic recommendations.

Regional applicability

Although the geographical origin is unspecified, this methodology paper describes a laboratory procedure that has global application. The ammonium acetate method remains a standard reference technique in soil testing worldwide, including United Kingdom soil science practice and quality assurance protocols.

Key measures

Cation exchange capacity (CEC), exchangeable calcium, exchangeable magnesium, exchangeable potassium, exchangeable sodium

Outcomes reported

The study describes and validates the ammonium acetate method for determining cation exchange capacity (CEC) and exchangeable bases (calcium, magnesium, potassium, sodium) in soil samples. The paper presents a standardised analytical protocol for these fundamental soil chemical measurements.
