“…By increasing the application of Ca and Mg fertilizers, the nitrogen efficiency in the soil can be regulated, leading to improved nitrogen utilization and absorption by maize. This, in turn, stimulates the synthesis of amino acids in maize, ultimately resulting in a higher content of essential amino acids and their components in maize kernels [ 31 ].…”

“…Hydrogen peroxide can be decomposed by CAT, an essential antioxidant enzyme, into oxygen and water, thereby decreasing its concentration and mitigating the inhibitory impact of oxidative stress on amino acid synthesis. Additionally, CAT can modulate amino acid synthesis through its impact on the gene expression of amino acid synthase [ 31 ]. An increase in the level of gene expression of amino acid synthase was observed in response to CAT overexpression, which consequently stimulated amino acid synthesis.…”

“…Ca and Mg are in a strong alkaline mineral state and are difficult to dissolve in water in the alkaline soil of the loess plateau. As a result, maize is incapable of absorbing and utilizing them [ 31 ]. Therefore, Ca and Mg nutrients are primarily absorbed by maize from the water-soluble and substitution states.…”

“…On the other hand, the concentrated precipitation in the loess plateau during the critical reproductive stage of maize causes the majority of the trace soluble Ca 2+ and Mg 2+ in the soil to be lost, resulting in an even lesser final Ca and Mg absorption and utilization by the maize. Consequently, the development of physiological symptoms is impeded by a deficiency of Ca and Mg nutrients, such as leaf yellowing, spot formation, and scorching, which impede photosynthesis and the translocation accumulation of organic matter [ 31 , 32 ]. Finally, the synthesis of amino acids in maize kernels is hindered.…”

Background The quality of maize kernels is significantly enhanced by amino acids, which are the fundamental building blocks of proteins. Meanwhile, calcium (Ca) and magnesium (Mg), as important nutrients for maize growth, are vital in regulating the metabolic pathways and enzyme activities of amino acid synthesis. Therefore, our study analyzed the response process and changes of amino acid content, endogenous hormone content, and antioxidant enzyme activity in kernels to the coupling addition of sugar alcohol-chelated Ca and Mg fertilizers with spraying on maize. Result (1) The coupled addition of Ca and Mg fertilizers increased the Ca and Mg content, endogenous hormone components (indole-3-acetic acid, IAA; gibberellin, GA; zeatin riboside, ZR) content, antioxidant enzyme activity, and amino acid content of maize kernels. The content of Ca and Mg in kernels increased with the increasing levels of Ca and Mg fertilizers within a certain range from the filling to the wax ripening stage, and significantly positively correlated with antioxidant enzyme activities. (2) The contents of IAA, GA, and ZR continued to rise, and the activities of superoxide dismutase (SOD) and catalase (CAT) were elevated, which effectively enhanced the ability of cells to resist oxidative damage, promoted cell elongation and division, and facilitated the growth and development of maize. However, the malondialdehyde (MDA) content increased consistently, which would attack the defense system of the cell membrane plasma to some extent. (3) Leucine (LEU) exhibited the highest percentage of essential amino acid components and a gradual decline from the filling to the wax ripening stage, with the most substantial beneficial effect on essential amino acids. (4) CAT and SOD favorably governed essential amino acids, while IAA and MDA negatively regulated them. The dominant physiological driving pathway for the synthesis of essential amino acids was “IAA-CAT-LEU”, in which IAA first negatively drove CAT activity, and CAT then advantageously controlled LEU synthesis. Conclusion These findings provide a potential approach to the physiological and biochemical metabolism of amino acid synthesis, and the nutritional quality enhancement of maize kernel.

“…Indeed, the increase in soil pH creates geochemical conditions to release of assimilable phosphorus which is complexed at low pH by Fe 2+ and Al 3+ . Rastija et al [36] showed that a gradual increase in pH induces an increase in bioavailable phosphorus in the soil by reducing exchangeable Al and the acid saturation rate.…”

Soil acidification is a major concern in Côte d'Ivoire. The present study examines the effect of an amendment based on crushed carbonate rock (dolomite and limestone) on soil chemistry and cocoa plant growth. To this end, cocoa seedlings were grown under controlled conditions under cover on soils taken from cocoa orchards in Aboisso (south-eastern Côte d'Ivoire). Soils were sampled at 0-20 cm, 20-40 cm and 40-60 cm. A representative composite sample of each horizon was then taken in a soil column. The experimental trial was conducted in total randomization with six repeated treatments (Dolomite 100%, Limestone 100%, Dolomite 50% + Limestone 50%) compared with the control, soil without amendment. After six months, the results showed that the application of carbonate did not induce a significant difference (p > 0.05) in cocoa seedlings growth. However, the amended soil showed improvement chemical properties compared to unamended soil. Soil treatments with limestone improved soil base cation content, CEC and pH, but all these parameters measured still lower to minimum threshold values for good cocoa tree growth. These results showed that the combination of dolomite and limestone appears to be the amendment with the greatest potential for improving the fertility of acid soils under cocoa. Field investigations should then be undertaken to assess the effect of this carbonate combination on soil acidity and fertility under natural conditions.
