“…As aforementioned, ultramafic soils present low Ca:Mg ratios, scarcity of macronutrients, pH close to neutrality, and elevated levels of metals such as Ni and Cr. Still, the ranges of these common features can vary at different locations, as the formation of soils depends not only on the nature and the abundance of the weathered parent material (e.g., Cr-bearing minerals are essentially chromite and magnetite, and to a lower extent serpentinite and pyroxene) but also on climate, topography, biota, and time [34]. Interestingly, data from Table 2 show a strong correlation between pH and Ni concentrations in soil (r = 0.975, p < 0.01).…”

Ultramafic areas are critical for nickel (Ni) phytomining due to the high concentration of this element in their soils and the number of hyperaccumulators they harbor. The aim of the present study was to evaluate the potential of the Morais massif, an ultramafic area in Portugal, for phytomining using the hyperaccumulator species Alyssum serpyllifolium subsp. lusitanicum. Soil samples and A. serpyllifolium specimens were collected in four locations of the Morais massif. After determination of Ni concentrations in the samples, the results show that soil pseudo-total Ni concentrations in sites number 1 and 2 are significantly higher than in the soil samples collected in the other two locations, with 1918 and 2092 mg kg −1 , respectively. Nickel accumulation is significantly greater in the aerial parts of plants collected at sites 1, 2, and 4, presenting Ni harvestable amount means of 88.36, 93.80, and 95.56 mg per plant, respectively. These results suggest that the sites with highest potential for phytomining are sites 1, 2, and 4. A nickel agromining system in these locations could represent an additional source of income to local farmers, since ultramafic soils have low productivity for agriculture and crop production. and Bragança massifs localized in the Trás-os-Montes region and harbor the nickel hyperaccumulator species Alyssum serpyllifolium subsp. lusitanicum [11]. Hyperaccumulators are remarkable plants that accumulate extreme amounts of metals (such as cadmium, cobalt, magnesium, and zinc) in their tissues while remaining sufficiently healthy to maintain a self-sustaining population [12]. It has been hypothesized that high metal accumulation in these plants may serve various ecological functions such as metal tolerance, resistance to environmental stress, competitive strategy (allelopathy), and defense against pathogens and herbivores [13][14][15][16]. In the case of A. serpyllifolium, there is evidence that the high concentrations of Ni protect the species against herbivores [13]. The first discovery of a Ni hyperaccumulator was made in 1948 by Minguzzi and Vergnano with the species Alyssum bertolonii [17]. In 1977, Brooks et al. defined a threshold for nickel hyperaccumulation of 1000 mg kg −1 in the dry matter of plant shoots [18]. Currently, there are approximately 500 plant species identified that hyperaccumulate nickel, making up 70% of all known hyperaccumulators [19]. Nickel hyperaccumulators are widely dispersed, reflecting the distribution of serpentine soils from which they absorb this element [20]. The plant A. serpyllifolium subsp. lusitanicum T. R. Dudley & P. Silva (or Alyssum pintodasilvae) was described by Dudley in 1967 [21,22]. It belongs to the Brassicaceae family, and it is classified as an herbaceous and perennial plant that presents a ramified stem that can reach 10 to 30 cm and yellow flowers. It is endemic to Morais and Bragança massifs and can accumulate up to 8000 mg kg −1 (dry weight) of nickel [11].Phytomining is a recent phytotechnology based on the use of hyperaccumulators t...

“…The presence of harmful Cr(VI) in soils and in turn in groundwater may be related to natural processes or/and human activities, such as transfer of weathered material from rocks and primary raw materials, wastes and/or application of large amounts of fertilizers and pesticides for a long time in cultivated areas. The European Soil Data Centre has established a link between the effects of metal bio-availability and metal bio-accumulation, and human health and negative impacts on ecosystems [25][26][27][28][29][30][87][88][89][90][91][92][93][94][95][96]. Dose-dependent differences in toxicities of elements, the particle size, and the oxidation state require serious consideration in health-risk assessments [90].…”

The application of Cr isotope compositions to the investigation of magmatic and post-magmatic effects on chromitites is unexplored. This study presents and compiles the first Cr stable isotope data (δ 53 Cr values) with major and trace element, contents from the Balkan Peninsula, aiming to provide an overview of the compositional variations of δ 53 Cr values in ophiolite-hosted chromitites and to delineate geochemical constraints controlling the composition of chromitites. The studied chromitites exhibit δ 53 Cr values ranging from −0.184% to +0.159% , falling in the range of so-called "igneous Earth" or "Earth's mantle inventory" with values −0.12 ± 0.11% to 0.079 ± 0.129% (2sd). A characteristic feature is the slightly positively fractionated δ 53 Cr values of all chromitite samples from Othrys (+0.043 ± 0.03% ), and the occurrence of a wide range of δ 53 Cr values spanning from positively, slightly negatively to the most negatively fractionated signatures (Pindos, δ 53 Cr = −0.147 to +0.009% ; Skyros, δ 53 Cr = −0.078 to +0.159% ). The observed negative trend between δ 53 Cr values and Cr/(Cr + Al) ratios may reflect a decrease in the δ 53 Cr values of chromitites with increasing partial melting degree. Alternatively, it may point to processes related to magmatic differentiation, as can be seen in our data from Mikrokleisoura (Vourinos).

“…It was also supported by previous study reporting that oil palm plantations established in the ultramafic ecosystem were faced with high content of Fe and Mg (Tufaila et al 2011). Other studies have also found that soil developed from ultramafic rock is frequently rich in Mg and also Fe B I OD I V E R S I TA S 21 (11): 5521-5530, November 2020 5522 released from mineral weathering (Lesovaya et al 2012;Bani et al 2014;Vithanage et al 2019). This circumstance is exceptionally contradictory because both elements have different effects on oil palm productivity.…”

Abstract. Alam S, Purwanto BH, Hanudin E, Putra ETS. 2020. Soil diversity influences oil palm productivity in ultramafic ecosystems, Southeast Sulawesi, Indonesia. Biodiversitas 21: 5521-5530. Ultramafic is a unique ecosystem with an environmental gradient due to its high soil diversity. Understanding soil diversity in ultramafic ecosystems is fundamentally required to support sustainable agriculture management, particularly in oil palm plantation. This study investigated the relationship between soil diversity and productivity of oil palm in ultramafic ecosystems, Southeast Sulawesi. The soil survey has taken in Oheo, Langgikima, and Routa districts. Soil sample was collected from various toposequence, including upper, middle, and lower slope to describe soil properties, including soil texture, pH, CEC, SOC, TN, Av-P, Exc-K, Exc-Ca, and Exc-Mg. Whilst observation of oil palm productivity was done by recording the fresh-weight of fruit yield in hectare unit during a month. The results showed that the soil characteristics from the three sites were significantly different in soil texture, pH, CEC, Av-P, Exc-Ca, and Exc-Mg. A similar trend was also recorded in oil palm productivity wherein the highest oil palm productivity was discovered in Oheo (556.41+96.26 kg ha-1), followed by Langgikima (501.11+54.84 kg ha-1) and Routa (163.19+17.55 kg ha-1). Our study founded: pH, CEC, Av-P, Exc-K, Exc-Ca, and Exc-Mg significantly affected the productivity of oil palm. Based on these results, the soil diversity highly affected oil palm productivity in ultramafic ecosystems.
