What is it about?
This paper focuses on the quantitative aspects of buffering theory applied to heterogeneous systems with multiple components. It highlights how the buffering properties of solid phase components modify with solubility, mainly due to protolytic and hydrolysis reactions or complexation processes.

Why is it important?
The study marks the first demonstration that the heterogeneous soil systems under examination exhibit buffer action towards all of the reactant components, not just in relation to the pH of the soil solution.
Perspectives
The derived equations enable the prediction of long-term changes in soil composition and reactivity under various environmental and anthropogenic factors. This tool allows for the evaluation of how shifts in pH, pollutant levels, and climate conditions will affect soil stability and nutrient availability, providing essential information for addressing future environmental challenges, including climate change. The research equips environmental scientists with tools to anticipate changes in soil composition due to increasing anthropogenic pressures. The predictive capabilities offered by this study are essential for assessing long-term impacts of atmospheric and pollutant changes on soil systems.
