A short, non-legume sod rotation is an efficient means of building up a depleted orchard soil.
plant of the group of the pulse family, 1670s, from French légume (16c.), from Latin legumen "pulse, leguminous plant," of unknown origin. One suggestion ties it to Latin legere "to gather" (see lecture (n.)), because they can be scooped by the handful. Used in Middle English in the Latin form legumen (late 14c.).
