Title: Relations between acidic aluminum and soil pH, clay, and organic matter

Abstract

The relationships of two measures of acidic Al contained in soil, namely KCl-exchangeable Al and nonexchangeable acidic Al (pH 4.8N NH/sub 4/OAC extractable Al minus KCl-exchangeable Al) with soil pH, clay, and organic matter content were evaluated statistically. Exchangeable Al concentrations were observed to be primarily related to pH. The nonexchangeable acidic Al was found to be significantly correlated with pH, clay, and organic matter content at the 1% level. However, nonexchangeable acidic Al correlated best with the organic matter which would imply the existence of aluminum-organic matter complexes in soil. A plot of nonexchangeable acidic Al with soil pH as determined in 1N KCl revealed an apparent maximum at a pH of approximately 4.1. These various interrelationships are combined into a proposed reaction scheme relating the various Al forms postulated to exist in soil.
