by which acid can we replace sulfamic acid to eliminate nitrite in a soil extract to determine the nitrate content by the DEVARDA method

Paul Milham

Unless you have high nitrite concentrations, e.g., around fertiliser bands, or conversion of nitrite is inhibited, nitrite concentrations are typically negligible. In any event, nitrite is readily determined colorimetrically.
