“…The micronutrients concentration was MnFeZnBCu with mean values of 415, 436, 172, 104, and 33 mg kg 1 (Table 2). Duarte (2003) reported values of 13.7, 3.6, 4.7, 0.1 1.3, 1.0 g kg 1 of N, P, K, Ca, Mg, S, and 32.3, 8.1, 4.0, 30.1, 6.0 mg kg 1 Fe, Mn, Cu, Zn, and B respectively. It is worth mentioning that micronutrient values are lower than those found in this research.…”
