Effect of extractant pH on the release of soil phosphorus, aluminium and iron by ammonium fluoride
Release of P, Al and Fe of five mineral soils in four-hour extraction by 0.1 M NH4F, pH 4.2—8.6, generally increased with decreasing pH of the extractant. Fluoride was a rather selective extractant of Al at pH 6.1—8.6 where the extractability of iron was low. NH4F, pH 4.2, released a great part of P...
