E experiments have been conducted on acid soils to determine the effects upon plant growth of various amounts of limestone having different degrees of fineness. It is quite generally accepted that the finer the limestone is ground the more quickly it neutralizes the soil acidity. Previous investigations have also quite clearly shown that the largest yields of legumes have been secured where the lime requirement of the soil had been met. Some recent work, however, seems to indicate that it is not necessary to meet the full lime requirement of a soil in order to secure crop yields comparable to those obtained on fully limed soils.
