“…For instance, soil-available Fe, Mn, and Zn followed patterns of SOC under trees along the elevational gradient at subtropical mountain (Table S2), while for shrubs at subtropical mountain, soil pH, instead of SOC, regulated elevational patterns of soil-available Fe, Mn, and Zn (Table S2). Our findings are consistent with a vast amount of previous studies confirming the pivotal role of soil pH and SOC concentration in determining soil base cation and micronutrient availabilities (Sharma et al, 2004;Wang et al, 2017). However, the fundamental roles of SOC and soil pH in controlling soil base cation and micronutrient availabilities was not universal, as suggested by the relatively weak relationships of soil pH and SOC with soil base cations under tree canopies at wet temperate mountain and with micronutrients under both tree and shrub canopies at dry temperate mountain (Table S2).…”

Abstract. To understand whether base cations and micronutrients in the plant-soil system change with elevation, we investigated the patterns of base cations and micronutrients in both soils and plant tissues along three elevational gradients in three climate zones in China. Base cations (Ca, Mg, and K) and micronutrients (Fe, Mn, and Zn) were determined in soils, trees, and shrubs growing at lower and middle elevations as well as at their upper limits on Balang (subtropical, SW China), Qilian (dry temperate, NW China), and Changbai (wet temperate, NE China) mountains. No consistent elevational patterns were found for base cation and micronutrient concentrations in both soils and plant tissues (leaves,

“…Elgala and Amberger (1982) reported that the DTPAextractable Fe increased as a result of incorporation of organic matter into the soil. Similarly, Sharma et al (2004) found that DTPA-extractable trace elements increased with an increase in organic carbon content.…”

“…Soil texture can be considered as the most important factor influencing the content and availability of trace elements. Sharma et al (2004) found that total content of Fe, Cu, Zn and Mn increased with an increase in clay and silt. Several other researchers reported also that the total trace elements increased with increasing silt and clay content (Katyal and Vlek, 1985;Katyal and Sharma, 1991;Sharma et al, 1992).…”

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.

“…Available Zn was extracted with diethylene-triaminepentaacetic acid (DTPA). Zinc concentrations in the solution were analyzed using a flame atomic absorption spectrometer (AAC) (Perkin Elmer SIMMA 6000, Norwalk, CT) (Sharma et al, 2004). For quality assurance, the National Institute of Standards and Technology reference plant materials (GBW # 08513) and soils (GBW # 08303) were used to check the efficiency of the digestion/extraction procedures and FAAS measurements.…”

Crop Zn content is different between various crop species. The purpose of the present study was to determine Zn response in seed of three species of Brassica (B. napus, B. juncea and B. campestris) when exposed to different Zn supply levels (0, 1, 5, 10 and 20 mg kg -1 ) in pot experiment. The results showed that the activities of antioxidant enzymes, net photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (Tr) in leaf, and dry weights of plant, straw, leaf and seed increased at CZn 2+ ≤5 mg kg -1 . The highest seed dry weight of three species were observed in 5 mg kg -1 Zn treatment, increased by 37.7%, 82.6% and 18.0% compared to the controls, respectively. The ultrastructural damage was found in the root tip cells for B. napus and YR in the presence of 20 mg kg -1 Zn, while intact structure of the root tip cells was observed in B. campestris. The total amino acid content of root exudates in B. juncea and B. napus was significantly higher than that of B. campestris in the presence of 1 and 20 mg kg -1 Zn. High supply level of Zn 2+ (20 mg kg -1 ) could promote the secretion of amino acids in root exudates. Dry weight (stem, leaf and seed) of B. napus reveal a decreasing trend when Zn supplied at levels above 10 mg kg -1 . As the increase of Zn supply level, the concentrations of Zn in seed of rape revealed an increasing trend. The best Zn supply level for having more biomass and more Zn in seeds of rape without toxic effects was observed at 10 mg kg -1 . The highest of Zn concentration in seed were observed in B. napus may be due to due to more root exudates. Zinc concentration in Zn-highefficiency species is related to the absorption capacity of the plant's roots and the ability to change soil Zn availability
