A simple legume-grass mixture was more productive than a grass + N mixture in 1958 but less productive in 1959, following legume depletion due to winter-killing. A low rate of nitrogen applied to depleted legume-grass swards was economically superior to high rates on either legume-depleted or all-grass pastures, but especially the latter. Results over the 5-year period suggest the desirability of seeding simple legume-grass mixtures with limited nitrogen amendments after legume depletion rather than seeding of either complex or all-grass mixtures.
