“…For example Scharrer and Jung (1955) showed that Mg fertilization of perennial ryegrass reduced the Ca and Na contents of the plants but did not affect the K uptake. But why does K affect Mg uptake and not or not so drastically vice versa?…”

Background Due to its unique chemistry magnesium (Mg) is subject to various cycling processes in agricultural ecosystems. This high mobility of Mg needs to be considered for crop nutrition in sustainable agricultural systems. The Mg mobility in soils and plants and its consequences for crop nutrition are understood, but recent findings in crop Mg uptake, translocation and physiology particularly under adverse growth conditions give new insights into the importance of Mg in crop production. Scope The aim of this review is to combine the knowledge on the origin and mobility of Mg in soils with the role of Mg in plant stress physiology and recent evidence on the principles of crop Mg uptake. The question is addressed whether the progress made in Mg research, particularly on the role of Mg in stress physiology, makes a revision of the development of Mg fertilization recommendations necessary. Conclusions New insights into Mg uptake and utilization but particularly into the role of Mg in increasing crop tolerance to various stresses indicate changes in the crop Mg demand under adverse growth conditions. Future work should incorporate these findings in optimization of site-specific balanced fertilization programs particularly under stress conditions.

“…When the plant takes up the nutrient in the form of ions there must be an electrostatic balance between the amount of positive cations and negative anions taken up (38). It has frequently been found that with a change in the cation dressing, the amount and type of anions remaining the same, the absorbed cations changed but not the sum of the basic cations (17,38,40). On the other hand, dressing with nitrogen in the form of ammonium nitrate causes a rise in both the anion and cation sums, the former rise being greater than the latter, so that the cation sum/anion sum ratio falls with increasing nitrate fertilisation (17,38,39).…”

That the cation/anion ratio may fall despite the specified electro static balance, is due to the fact that the nitrate in the plant is reduced, releasing an OH ion which can be exchanged for nitrate in the nutrient solution.…”

Nitrolime (100-310 kg/ha N) was applied in spring to 10-year-old trees growing in a medium-heavy river ridge soil; 80 kg P2O5 and 200 kg K2O were also applied each year. In all but the first year more foliage and shoots occurred after the 310 kg than after lighter N treatments. Increasing N treatments were accompanied by increasing Mg and N and decreasing K, P and Ca contents in the leaves. (Abstract retrieved from CAB Abstracts by CABI’s permission)

“…Results indicating reciprocal or antagonistic relationships in plants between K and Ca, Mg or Na have been reported by several workers (Lucas & Scarseth, 1947;Epstein, 1961;Epstein, Rains & Schmid, 1962;Handley, Metwally & Overstreet, 1965;Mengel & Helal, 1967;Hiatt, 1969;Ragab, 1972). Generally an excess of one cation species in the soil or nutrient solution redvices the net uptake of other cations, whereas the sum of cations in the plant tissue often remains nearly constant (Scharrer & Jung, 1955). With yield response to applied K concentrations of other uniformily applied nutrients usually decrease because of dilution with dry matter.…”

SUMMARYPot experiments were carried out using a system in which root mats were in contact with a Danish soil for 24, 72 or 168 h. Different rates of K fertilizer (0–80 mg K/100 g soil) resulted in marked responses at 168 h of roots–soil contact, however moderately or little responses at 72 or 24 h had occurred. Marked reciprocal K–Ca, K–Mg, K–Na relationships with yield response to rates of applied K were attributed to both dilution and antagonism. The latter was not apparently brought about by competition for the carrier binding site but from the unspecific replacement competition which occurred in the interior of plant cells and not in the outer surface of the cell root membrane.
