Magnesium Availability as Affected by Deficient and Adequate Levels of Potassium and Lime1

Abstract

Abstract

The availability of soil Mg was measured on 7 major soil types of Alabama by growing Sudangrass and ladino clover in the greenhouse. The plants were grown at deficient and adequate levels of available K and lime. Plant growth and plant content of Ca, Mg, and K were measured. Total up-take of Mg was used as a measure of its availability. Growth response to Mg by the two crops occurred on the same soils. Soils that had < 4% of the cation-exchange capacity as Mg were Mg-deficient. Mg-deficient plants contained 0.25 me. or less of Mg per g. of dry material. On Mg-deficient soils, the availability of Mg to both crops tended to be greater at the higher K level. However, the availability of Mg on the same soils was less at the higher soil pH. Mg availability on soils not deficient in Mg in general was affected in the reverse.
