“…Examples of apparent B mobility based upon the high B concentration in fruit and in flowers were reported for pear, apple, and cherry (Crandall et al, 1981), as well as for olive (Delgado et al, 1994), which need large amounts of B (Hartmann et al, 1966). The effect of B deficiency on grain set failure is well documented in cereals (Ambak and Tadano, 1991). Moreover, an increase was observed in leaf B concentration during the period June-July, followed by a decrease, as occurs in the present experiment (Fernandez-Escobar et al, 1999).…”

Ten-year-old olive plants, (Olea europaea L.) cv. 'Chondrolia Chalkidikis,' were cultured under ambient conditions in 50 L plastic pots containing inert sand-perlite medium and irrigated for a period of 18 months with 50% Hoagland's nutrient solutions containing 0, 0.5, and 5.0 mg boron (B) L −1 . The highest B concentration in the leaves was observed during the period May-June, and declined afterwards. Potassium (K) concentration in the leaves was the lowest in winter, but reached the maximum during the period June-July. Conversely, calcium (Ca) and magnesium (Mg) concentrations increased during the period June-March of the following year. No differences in phosphorus (P), iron (Fe) and zinc (Zn) concentrations were recorded between the treatments. However, P concentration fluctuated from 0.1% to 0.3% D.M. (dry matter) during the year, showing many minima and maxima. Iron and manganese (Mn) concentrations increased gradually from January of the first year to January of the second year and declined afterwards. The highest Fe concentration was about 200 mg kg −1 (D.M.) while leaf Mn varied between 10-50 mg kg −1 (D.M.). Leaf nitrogen (N) concentration was more or less constant during the experiment. The −B and the +5.0 mg B L −1 treatments reduced significantly the percentage of perfect flowers and affected B concentration of inflorescences, as it was 3-4 times greater with 5.0 mg B L −1 in comparison with the control.

“…Total Fe had the highest concentration in peat compared to other micronutrients analyzed in this study, which accounted for 20 times of total Zn and 90 times of total Cu. The total Fe, Cu, and Zn recorded in this study were in the common range of peat soil reported by previous researchers (i.e., Lucas 1982;Ambak et al, 1991;Abat et al, 2012;Dhandapani et al, 2018;Nelvia 2018;Hashim et al, 2019;Dhandapani et al, 2021). Total Fe, Cu, and Zn distribution were strongly influenced by their age, peat thickness, and distance from the canal.…”

Extensive utilization of fragile tropical peatlands ecosystem encourages a better understanding of spatiotemporal micronutrients distribution. The distribution of total Fe, Cu, and Zn in peat and their relationship with environmental factors were studied under oil palm plantation, Pangkalan Pisang, Koto Gasib, Riau, Indonesia. Peat samples were taken compositely inside the block using a combination of six factors, including a) the oil palm age (<6, 6-15, >15 years old), b) the peat thickness (< 3 and >3 m), c) season (rainy and dry), d) the distances from the secondary canal (10, 25, 50, 75, 100, and 150 m), e) the distances from an oil palm tree (1, 2, 3, and 4 m), and f) the depth of sample collection (0-20, 20-40, and 40-70 cm from the peat surface). Total Fe, Cu, and Zn were determined by the wet digestion method. These micronutrients observed in this study possessed high variability; however, they were within the expected range in tropical peatland. The entire micronutrients were statistically different by oil palm age, peat thickness, and distance from canal. Meanwhile, total Cu and Zn were also significantly different at each season. The oil palm age, peat thickness, and distance from the canal were the common factors controlling total Fe, Cu, and Zn in peat significantly. Moreover, total Cu and Zn were also dictated by season, distance from the oil palm tree, and depth of sample collection. Based on visual interpretation in PCA (principal component analysis), all micronutrients were categorized into two groups, separated by 2 m distance from the oil palm tree and 20 cm depth from the soil surface. Our study also highlights the dominance of the dilution over the enrichment process in peat, which requires further research to formulate micronutrients fertilization, especially for an extended cultivation time.

“…In all hulled and hulless varieties, changes, or reductions in the distribution of other nutrients (Ca, K, Fe, and Cu) were observed in the spoiled samples. These vital nutrients are responsible for healthy grain and the growth of barley [53]; hence, their degradation in storage means a loss of germination, and a loss in germination of malting barley below 95% is not recommended if it is used for malt production [15]. The utilization of synchrotron X-ray fluorescence imaging (SR-XFI) proved valuable in accurately mapping the changes occurring during post-harvest storage in barley due to spoilage.…”

Four varieties of barley (Esma, AC Metacalf, Tradition, and AB Cattlelac), representing four Canadian barley classes, were stored at 17% moisture content (mc) for 8 week. Stored barely was characterized using synchrotron X-ray phase contrast microcomputed tomography, synchrotron X-ray fluorescence imaging, and mid-infrared spectroscopy at the Canadian Light Source, Saskatoon. The deterioration was observed in all the selected varieties of barley at the end of 8 week of storage. Changes due to spoilage over time were observed in the grain microstructure and its nutrient distribution and composition. This study underscores the critical importance of the initial condition of barley grain microstructure in determining its storage life, particularly under unfavorable conditions. The hulled barley varieties showed more deterioration in microstructure than the hulless varieties of barley, where a direct correlation between microstructural changes and alterations in nutritional content was found. All selected barley classes showed changes in the distribution of nutrients (Ca, Fe, K, Mn, Cu, and Zn), but the two-row AC Metcalf variety exhibited more substantial variations in their nutrient distribution (Zn and Mn) than the other three varieties during storage. The two-row class barley varieties showed more changes in biochemical components (protein, lipids, and carbohydrates) than the six-row class varieties.
