Table 2. Maximum Soluble Micronutrient Concentrations in Soil Extracts Obtained in the Soil Batch Experiment with Both Ligands ([S,S]-EDDS and EDTA)^a.

	S₁			S₂				S₃
	Fe	Mn	Zn	Cu	Fe	Mn	Zn	Cu	Fe	Mn	Zn	Cu
maximum solubilized metal with [S,S]-EDDS (μmol/L)	12.1	3.94	2.61	20.3	27.3	68.0	2.04	19.2	32.6	151	2.03	21.2
maximum solubilized metal with EDTA (μmol/L)	5.52	4.88	2.23	2.36	5.45	4.08	1.82	4.53	24.9	27.4	2.06	8.00
available in soil (μmol/L)	4.34	0.69	1.70	2.73	16.3	11.2	1.40	8.68	11.5	10.2	0.61	2.90

Values are means ± SD (n = 3). The [S,S]-EDDS and EDTA were added at measured concentrations of 401 and 500 μM. For comparison also the calculated concentration of the initially available metals in each soil extract is presented.
