Effect of magnesium and ph of the soil on greenhouse grown alfalfa in 3 types of soil of quebec canada


, : Effect of magnesium and ph of the soil on greenhouse grown alfalfa in 3 types of soil of quebec canada. Canadian Journal of Soil Science 60(2): 275-284

Alfalfa (Medicago sativa L. 'Saranac') was grown under greenhouse conditions to determine the changes in Mg response and availability following variation in soil pH. The rates of Mg applications were 0, 25, 50, 100 and 200 ppm of Mg calculated on soil dry weight basis. Soil pH was adjusted to 5.0 (or original) 6.0, 6.5 and 7.5. A 40% yield increase was recorded on Greensboro loam following Mg fertilization. The increase in yields due to Mg was 23% on the 2 others soil types. The Mg contents of plant and soil increased with rate of Mg applied to soil. In general, the response of alfalfa was increased by liming soils and the Mg content of alfalfa was decreased. The availability of Mg in soils was also lowered by liming. The Mg requirement of soils ranges 25-100 ppm depending on pH and soil types.
