Status of selenium and trace elements in some arid soils cultivated with forage plants: A case study from Saudi Arabia. , respectively. Meanwhile, in soil samples collected from corn farms, available Fe, Mn, Zn, Cu, and Mo ranged from 1. 70-8.35, 0.74-10.5, 0.82-3.12, 0.32-3.91, undetectable-0.04 mg kg -1 , respectively. The shoot contents of Se, Mo, Zn and Cu were low and deficient in alfalfa and corn plants. However, it was observed that the shoot contents of Fe and Mn were sufficient. Based on correlation coefficients and multivariate analyses including principal component (PCA) and cluster analyses (CA), soil properties of clay content, CEC and OM altered trace elements availability and consequently can modify the response of forage plant in study area.
