Effect of fluctuations in pH on the availability of K, Mg, Cu, Mn, Zn, and Fe Ulansky, Sherry M.

Abstract

An exploratory study was conducted to determine the effect of fluctuations in pH on the availability of K, Mg, Cu, Mn, Zn, and Fe. Two soils were selected for study which had differing buffering capacities based on their clay and organic matter contents. The pH of soil samples was manipulated with either HC1 or CaC03 and then allowed to incubate. Mineralogical changes, as well as, chemical analysis indicated that fluctuations in pH may have a moderating effect on mineral weathering and precipitation reactions which in turn influences nutrient release, fixation, and availability. Changes in organic matter content with fluctuating pH appear to influence the behaviour of the trace metals and may be responsible for the development of pH-dependent charge CEC.
