Placements at 2 rates each of phosphate, potash, and limestone were compared on 2 legume‐grass mixtures for a period of 3 years. The placements were surface, plow sole, and mixed with the plow layer. The mixtures were alfalfa‐orchardgrass and Kobe lespedeza‐Dallisgrass. Lime placement effects on the alfalfa‐orchardgrass mixture were very pronounced. The surface application was least effective and mixing with the plow layer was the most favorable placement. Surface placement of phosphate was inferior to the other two placements the first year while placement of potash had no effect. Placement of phosphate, potash, or lime did not measurably affect growth of the lespedeza‐Dallisgrass mixture.
