WebApr 11, 2024 · The phytate solubility in the soil is also dependent on the phytase enzyme. The activity of phytase is affected by soil pH and is optimum in the range of 2.5–8.0 and then decreases with an increase in pH. In addition, because of its sorption onto soil minerals like montmorillonite, phytase action is suppressed (Leprince and Quiquampoix, 1996).
