“…Large amounts of Al 3+ may decrease Mg uptake due to a direct antagonistic effect or due to a decreased rate of root growth or both (1,2,3,4). The most common way of increasing Mg availability to plants grown in acid soils has been the use of dolomitic lime (5,6,7,8) The use of calcitic lime may increase (9), decrease (5,7) or not affect (6) Mg uptake by plants depending on the widening of the Ca:Mg ratio and related pH factors. Due to differences between soils and to selectivity of plants, the Ca:Mg ratio may vary considerably before any effect of antagonism between Ca and Mg may be noticed (10,11).…”

Since ryegrass (Lolium sp.) is a widely grown cool-season forage grass, its magnesium concentration is of special interest to ruminant livestock producers. This study was conducted to investigate the effect of calcitic or dolomitic lime addition on dry matter yield and mineral composition of hybrid ryegrass, Lolium (multiflorum x perenne x perenne) grown in eight acidic soils. Each soil received two levels of calcitic or dolomitic lime, L(C 1 ) and L(C 2 ) or L(D 1 ) and L(D 2 ), which raised pH to approximately 5.3, and 6.0. Dry matter yield response was obtained only in soils having an initial % Al saturation 59, % Mg saturation 10 and % Ca saturation 21. Only in one soil, which had an initial exchangeable Mg level of 0.05 cmol c /kg of soil, was response to dolomitic lime higher than that obtained with calcitic lime. Magnesium concentration in dry matter was increased by both levels of dolomitic lime with the increase dependent on the rate used and on the initial level of exchangeable Mg. The average Mg concentration increased from 0.8 to 3.9 g/kg, from 1.6 to 3.6 g/kg, and from 2.6 to 3.9 g/kg, when ryegrass was grown in soils having low, medium, and high initial exchangeable Mg levels, respectively. Mg concentration in the ryegrass tended to be lower in the unlimed soils than when calcitic lime was used, 1.1 vs. 1.4 g/kg, when the soils had low to medium exchangeable Mg levels.
