A? the result of an investigation at the University of Illinois it has been shown that dolomite up to 40 per cent, proves beneficial to plant growth. The results indicate that dolomite and niagnesian limestone will not be detrimental as applied in agricultural practices. Increasing the size of application increases the calcium and magnesium contents of plants. Details of the investigation will be found in the ?Jownal of Agricultural Research, Vol. VI, No. 1
