NettetThe DTPA methodology published by Lindsay and Norvell (1978) and repeated in Carter (1993) was optimized for the extraction of the trace elements Zn, Fe, Mn, and Cu in soil. DTPA is used in this extraction because it has a favourable combination of stability constants for forming complexes with the four above-noted ions (Lindsay and Norvell, … Nettet11 Zn (ppm) 1.07 DTPA extraction method (Lindsay and Norvell 1978) 12 Cu (ppm) 3.41 DTPA extraction method (Lindsay and Norvell 1978) 13 Fe (ppm) 9.01 DTPA extraction method (Lindsay and Norvell 1978) +
