Abstract
In pot trials, Sudangrass was given various combinations of 1 or 0.5 meq calcium nitrate, 0.5 meq sodium nitrate, 0.33 meq magnesium nitrate, 0.25 meq potassium nitrate and 1 meq nitric acid/100g soil. The plant Mg content decreased with application of K and increased with application of Mg. A significant yield response to applied Mg was found when Mg was applied with Ca, Na and K; as the soil was not deficient in Mg it was concluded that this was due to an improvement in soil ionic balance. Application of Mg in combination with Ca, Na and K decreased plant K content, increased Mg content and decreased the K:(Ca + Mg) ratio. The results suggested that high levels of other nutrients may adversely affect the Mg nutrition of crops on alkaline soils not abundantly supplied with available Mg
