Synopsis Liming increased the dry matter yields of oats and of an alfalfa‐orchardgrass mixture. Response to K increased with increased base saturation of the soil, and survival of alfalfa plants on soil limed to pH 5.5 or higher was largely dependent on K supply. Alfalfa was the dominant species where there was sufficient K for both components and orchardgrass dominated where K was limited. Total available carbohydrates in the storage organs of each species increased with K fertilization.
