“…Magnesium is generally more soluble under calcareous soil conditions (Jalali et al, 2020) and, here, [Fe(mpp) 3 ] addition had a low impact on this mineral accumulation (no significant changes when compared to the control), while FeEDDHA supplementation led to a significant decrease in root Mg concentration and increase in the shoots. Sodium also decreased in the roots of plants treated with FeEDDHA.…”

Iron (Fe) deficiency chlorosis (IDC) affects the growth of several crops, especially when growing in alkaline soils. The application of synthetic Fe‐chelates is one of the most commonly used strategies in IDC amendment, despite their associated negative environmental impacts. In a previous work, the Fe‐chelate tris(3‐hydroxy‐1‐(H)‐2‐methyl‐4‐pyridinonate) iron(III) [Fe(mpp)3] has shown great potential for alleviating IDC in soybean (Glycine max) in the early stages of plant development under hydroponic conditions. Herein, its efficacy was verified under soil conditions in soybean grown from seed to full maturity. Chlorophyll levels, plant growth, root and shoot mineral accumulation (K, Mg, Ca, Na, P, Mn, Zn, Ni, and Co) and FERRITIN expression were accessed at V5 phenological stage. Compared to a commonly used Fe chelate, FeEDDHA, supplementation with [Fe(mpp)3] led to a 29% higher relative chlorophyll content, 32% higher root biomass, 36% higher trifoliate Fe concentration, and a twofold increase in leaf FERRITIN gene expression. [Fe(mpp)3] supplementation also resulted in increased accumulation of P, K, Zn, and Co. At full maturity, the remaining plants were harvested and [Fe(mpp)3] application led to a 32% seed yield increase when compared to FeEDDHA. This is the first report on the use of [Fe(mpp)3] under alkaline soil conditions for IDC correction, and we show that its foliar application has a longer‐lasting effect than FeEDDHA, induces efficient root responses, and promotes the uptake of other nutrients.

“…Ca and Mg exhibit similar chemical properties, and both are doubly positively charged in the soil-water phase and at the soil cation exchange sites. 17 The importance of Mg and Ca lies not only in the role they play in plant growth but also in their interaction with each other. In Citrus sinensis (L.) Osbeck seedlings, Mg-deficiency induced leaf vein lignification, enlargement, and cracking.…”

A metal tolerance protein, MTP10, is required for the calcium and magnesium homeostasis in Arabidopsis

Nutrient antagonism typically refers to the fact that too high a concentration of one nutrient inhibits the absorption of another nutrient. In plants, Ca 2+ (Calcium) and Mg 2+ (Magnesium) are the two most abundant divalent cations, which are known to have antagonistic interactions. Hence, maintaining their homeostasis is crucial for plant growth and development. In this study, we showed that MTP10 (Metal Tolerance Protein 10) is an important regulator for maintaining homeostasis of Mg and Ca in Arabidopsis. The mtp10 mutant displayed severe growth retardation in the presence of excess Mg 2+ , to which the addition of Ca 2+ was able to rescue the phenotype of mtp10 mutant. Additionally, the deficiency of Ca 2+ in the culture medium accelerated the high-Mg sensitivity of the mtp10 mutant. The yeast complementation assay suggested that AtMTP10 had no Ca 2+ transport activity. And the ICP-MS data further confirmed the antagonistic relationship between Ca 2+ and Mg 2+ , with the addition of Ca 2+ reducing the excessive accumulation of Mg 2+ and high-Mg inhibiting the uptake of Ca 2+ . We conclude that the Arabidopsis MTP10 is essential for the regulation of Mg and Ca homeostasis.

“…On the other hand, on K-depleted soils, the role of -ΔΚ 0 /CEC is limited due to the negligible slope value, whereas the increase of the constant value is the main parameter of determining K G formation, resulting in an increase of its values. Recently, Jalali et al (2020) reported that exchange isotherm curves of K could be divided into sections which indicate low, medium, and high affinity sites, suggesting that K which is specifically adsorbed onto the edge, and interlayer positions is in equilibrium with the low concentration of soluble K.…”

The objective of this study was to obtain sufficient estimates of quantity-intensity (Q/I) parameters using a single-point method, and to evaluate the role of cation exchange capacity (CEC) and Gapon selectivity coefficient (K G ) as parameters that improve prediction model's estimation accuracy or explain its limitations under conditions of K deficiency. Regression models were applied on raw data derived from previews Q/I experiments conducted on 20 soils of northern Greece at initial and K-depleted treatment states. Relationships between soil K adsorbed or released (ΔΚ), or K activity ratios at each K addition (AR K ) and respective values at equilibria (-ΔΚ 0 , AR e K ) were tested to find the best fitting models. CEC was included in regression models to improve their performance, while K G parameter was assessed for initial and K-depleted soils. The study showed that Q/I parameters were well predicted with the single-point method for a wide range of K saturation ratios, by applying 0.01 M CaCl 2 and 10 mg L −1 K addition. Furthermore, CEC significantly improved model's estimation accuracy. Under the ΔG breakpoint of − 14.67 kJ mol −1 , specific adsorption sites of the soil inner-sphere region weaken the single-point prediction efficacy, as was clearly indicated by the K G formation under conditions of K depletion. The study suggests that the proposed method is applicable for estimating Q/I parameters for soils covering a wide range of K activity ratios. Moreover, CEC and K G parameters constitute useful tools in improving prediction model's estimation accuracy, or explaining their limitations under conditions of K deficiency.
