Webneutral soils. As most of the organic P inputs to soil are phosphate diesters, it therefore seems likely that phosphodiesterase activity regulates labile organic P turnover in pasture soils. The low phosphodiesterase activity in acidic soils may be linked to the dominance of fungi or an effect of sorption on the enzyme. WebOct 1, 2024 · Phosphodiesters are considered to be important for the replenishment of P i in soils because their phosphate groups are shielded from ionic interactions, making them less likely Enzyme...
