“…For example, oat, wheat, soybean or peaches are very susceptible, whereas maize and rye are much less susceptible (Reuter et al 1988). In cereals, such as barley and wheat, Mn deficiency leads to significant yield reductions and may cause complete loss of crops during the winter.…”

Silicon protects plants against various biotic and abiotic stresses, including metal toxicity. Under a high metal concentration, Si can externally decrease metal availability to the plant by its precipitation in the growth media, and Si also affects the metal distribution inside the plant, diminishing the damage. Could Si also protect plants against metal deficiency stress? Recently, the physiological role of Si in relation to micronutrients deficiency symptoms has been assessed in several plant species in hydroponics. In cucumber, Si supply mitigated the symptoms of Fe deficiency, but this effect was not clear under Zn-or Mndeficiency conditions. The main factor controlling this beneficial effect seems to be the Si contribution to the formation of metal deposits in the root and/or leaves apoplast and its role in their following remobilization when required. The enhancement of the content of long-distance transport molecules (such as citrate) due to Si addition should also contribute to the metal transport from root to shoot, which will diminish deficiency symptoms.

The influence of various nitrogen (N) and sulphur (S) forms on the uptake of manganese (Mn) in young spring barley (Hordeum vulgare L cv Golf) plants was examined in both a hydroponic system and in a soil-based system. The soil was a typical Danish Mn-deficient soil viz. a sandy loam soil developed on old marine sediments. Plants growing in solution culture with NO − 3 as the only N source had a higher Mn uptake than plants receiving mixtures of NO − 3 and NH + 4 . These findings were opposite to the results obtained in the soil-based experiments, where plants fertilized with NO − 3 as the only N source accumulated much less Mn than plants fertilized with NH + 4 . Combining the results of these experiments confirmed that NH + 4 acted as a powerful antagonist to Mn 2+ during uptake but that this antagonistic effect was more than compensated for by the influence of NH + 4 in reducing plant-unavailable Mn(IV) to plant-available Mn(II) in the soil. Furthermore the soil experiments showed that fertilizers containing sulphur in the form of reduced S (thiosulphate) had a strong mobilizing effect on Mn, and enabled the plants to accumulate large amounts of Mn in the biomass compared with oxidized S (sulphate). Thus, fertilization with thiosulphate may be very effective in alleviating Mn-deficiency in soils developed on old marine sediments where Mn availability is limiting plant growth.

“…Apesar de ser o Mn +2 absorvido pelas raízes preferencialmente transportado para os pontos de crescimento (folhas, raízes e sementes) (Reuter et al, 1988), sua baixa mobilidade no floema de plantas vem dar suporte à base fisiológica para a falta de sucesso da adubação foliar com Mn, em plantas deficientes, dada a menor redistribuição do Mn +2 aplicado à folhagem para aqueles tecidos. Sob condições de deficiência, a absorção do nutriente propicia uma recuperação inicial, mas, caso o estresse continue ou se repita, a formação da nova folhagem é comprometida.…”
