WebAims and background The DGT test is an emerging soil test to measure available phosphorus (P) in soils. Data from previous pot and field trials suggested a superior predictive power of this test relative to estab-lished soil P tests. Modeling also predicted that the critical DGT value (to obtain 80 % of the maximum yield) is plant specific.
