“…The soil solution only contains a small portion of the total Ca 2+. Only Ca 2+ can be absorbed by plant roots from soil solutions ( Ramírez-Builes et al., 2020 ). The kind of soil, the mineral composition of the colloids, the pH, the amount of organic carbon, the presence of humid acids, and the cation exchangeable capacities are just a few variables that may affect the amount of Ca 2+ that is present in the soil solution ( Ramírez-Builes et al., 2020 ).…”

Background For developing countries such as Ethiopia, coffee is a commodity of great economic, social, and environmental importance. No detailed investigations have been performed on the contents of essential and toxic metals in coffee beans and soil in this study area. Methods The levels of essential metals (Na, K, Ca, Zn, Mn, Cu, Co, Cr, Ni) and toxic elements (Pb and Cd) were investigated in coffee beans (coffee growing farmland and coffee washed plants) and soil samples (from farmland) using flame atomic absorption spectrometry (FAAS) and flame emission atomic spectroscopy. We selected six (20%) administrative units (kebele) with purposive sampling techniques based on their coffee production capacity in Dale Woreda for soil testing. After coffee sample preparation in a microwave system with HNO3and H2O2 reagents, the accuracy of the optimized procedure was evaluated by analysing the digest of the spiked samples. Soil samples were abridged with a slight revision of the EPA 3050B acid digesting method. ANOVA was used to determine the significant differences in the mean concentration of metal within coffee beans from farmland at the various sampled sites at the p < 0.05 significance level. To correlate the effect of one metal concentration on other metals in the coffee bean samples, Pearson correlation matrices were used. Results Calcium had the highest concentration (1,355 ± 18.02 mg kg−1) of macroelements in soil samples, followed by K (681.43 ± 1.52 mg kg−1). Similarly, Na (111.63 ± 0.35 mg kg−1), Cu (49.96 ± 0.99 mg kg−1), Co (5.43 ± 0.31 mg kg−1), Mn (0.62 ± 0.238 mg kg−1), Ni (0.194 ± 0.01 mg kg−1), and Zn (0.163 ± 0.007 mg kg−1) were detected among the microelements in the soil samples. Pb and Cr were not detected in all soil samples. Potassium (K) was found to have the highest concentration (99.93 ± 0.037 mg kg−1), followed by Ca (17.23 ± 0.36 mg kg−1), among the macroelements in coffee beans from farmers’ farms. Similar to coffee beans from farmland, samples from washed plants also contained the highest K (77.93 ± 0.115 mg kg−1), followed by Ca (4.33 ± 0.035 mg kg−1). Metal levels in coffee bean samples from farmland are in the following order: K>Na>Ca >Mn>Cu> Ni>Zn. Metal levels were found to be K>Na>Ca >Mn>Cu> Zn>Ni in coffee beans from the washed plants. Co, Cr, Pb and Cd were no detected in all coffee bean samples. Except for calcium, potassium and manganese, the levels of metals in coffee beans from farmland and washed plants were not significantly different at the 95% confidence level within a kebele. Conclusions We observed permitted levels of macro- and trace elements in coffee beans from farmlands and washed plants. Only in the soil samples are cadmium concentrations higher than those permitted for agricultural soil recommended by the WHO and FAO. Overall, there is no health danger linked with the use of coffee beans due to detrimental and trace heavy metals.

“…It acts as an activator or cofactor of enzymes in carbohydrate metabolism and plays an important part in photo-oxidative defense ( Guo et al, 2015 ; Hauer-Jákli & Tränkner, 2019 ; Grzebisz, 2013 ; Chen et al, 2018 ). On the other hand, some studies indicate antagonistic relations between Mg 2+ and Ca 2+ in plants ( Gransee & Führs, 2013 ), a synergistic effect of Ca 2+ and K + uptake, and no influence on Mg +2 uptake in the coffee plant ( Ramírez-Builes et al, 2020 ). Nonetheless, these studies mostly describe competitive absorption of Mg 2+ and Ca 2+ from the soil fertilized with these nutrients.…”

“…On the other hand, external application of mineral nutrients to increase drought tolerance still has not been studied well. Among a wide range of biogenic macro- and microelements, calcium is of particular interest because it participates in signal transduction under unfavorable environmental conditions ( Zhang et al, 2015 ; Edel et al, 2017 ; Singh, Parihar & Prasad, 2018 ; Thor, 2019 ; Hosseini et al, 2019 ; Ramírez-Builes et al, 2020 ). Calcium takes part in most of cellular signaling processes, and its important role in early stress detection and triggering a response has been demonstrated in many crops ( Kim, 2009 ; Upadhyaya et al, 2012 ; Singh, Parihar & Prasad, 2018 ; Thor, 2019 ; Hosseini et al, 2019 ).…”

Background Drought is one of the major factors reducing the yield of many crops worldwide, including the tea crop (Camellia sinensis (L.) Kuntze). Calcium participates in most of cellular signaling processes, and its important role in stress detection and triggering a response has been shown in many crops. The aim of this study was to evaluate possible effects of calcium on the tea plant response to drought. Methods Experiments were conducted using 3-year-old potted tea plants of the best local cultivar Kolkhida. Application of ammonium nitrate (control treatment) or calcium nitrate (Ca treatment) to the soil was performed before drought induction. Next, a 7-day drought was induced in both groups of plants. The following physiological parameters were measured: relative electrical conductivity, pH of cell sap, and concentrations of cations, sugars, and amino acids. In addition, relative expression levels of 40 stress-related and crop quality–related genes were analyzed. Results Under drought stress, leaf electrolyte leakage differed significantly, indicating greater damage to cell membranes in control plants than in Ca-treated plants. Calcium application resulted in greater pH of cell sap; higher accumulation of tyrosine, methionine, and valine; and a greater Mg2+ content as compared to control plants. Drought stress downregulated most of the quality-related genes in both groups of tea plants. By contrast, significant upregulation of some genes was observed, namely CRK45, NAC26, TPS11, LOX1, LOX6, Hydrolase22, DREB26, SWEET2, GS, ADC, DHN2, GOLS1, GOLS3, and RHL41. Among them, three genes (LOX1, RHL41, and GOLS1) showed 2–3 times greater expression in Ca-treated plants than in control plants. Based on these results, it can be speculated that calcium affects galactinol biosynthesis and participates in the regulation of stomatal aperture not only through activation of abscisic-acid signaling but also through jasmonic-acid pathway activation. These findings clarify calcium-mediated mechanisms of drought defense in tree crops. Thus, calcium improves the drought response in the tea tree.

“…e direct relationship between calcium and better bean moisture content would be due to its direct influence on the growth and development of the plant through better root growth, vigorous plant growth, improvement in uptake of potassium nutrients [52], and relative yield increment on coffee plants [53]. According to Ramalho et al [54], the contribution of calcium in stabilizing chlorophyll and maintaining better photochemical efficiency of leaves makes the nutrient important in coffee production.…”

A comprehensive examination of the physical and cup quality of Kafa Biosphere Reserve coffees was essential to identify the inherent qualities of the coffees in connection with the area’s soil physical and chemical characteristics. As a result, preliminary coffee quality data was acquired from bean physical and cup quality examination of coffees derived through a three-stage nested design combining districts (Gimbo, Gawata, and Decha), coffee production systems (forest, semiforest, and garden), and coffee processing methods (wet, semiwet, and dry). Representative soil samples were collected according to the sampling structure and analyzed following the standard procedures. Multiple factor analysis and Pearson’s correlation coefficient analysis were applied to the collected data. According to the results of multiple factor analysis, the Gimbo and Decha districts are not significantly different from each other in terms of coffee quality. However, they are substantially different from the Gawata district in terms of coffee quality. Similarly, within each district, there are no clear differences in coffee production systems. However, the production systems of districts varied significantly. The coffee processing method had a pronounced effect on the overall quality and preliminary grade, physical and raw quality variables of coffee. Screen retention (14) was correlated with soil iron, but it was related negatively to boron and sodium contents. A significant and positive relationship was observed between green coffee bean moisture content and soil potassium, calcium, magnesium, boron, sodium, organic carbon, silicon content, and soil pH. A positive and significant relationship between soil molybdenum and the coffee quality variable was observed across the studied districts whereas most soil micronutrients, specifically, zinc, sulfur, and manganese, were significantly and negatively related to the organoleptic qualities of the coffees. Further investigation that includes the effects of elevation is recommended in future studies.
