Synopsis

Synopsis

Seedling weight, dry matter yield and root weight of alfalfa plants seeded in small plugs of limed (pH=7.0) soil in an acid soil medium (pH=4.8) were significantly greater than when seeded directly in acid soils or in plugs of unlimed soil, but yields were significantly lower than where all the soil in a pot was limed to a pH of 5.6. A soil pH of 5.9 was adequate for establishing alfalfa and orchardgrass seedlings.
