Brown and Johnson have found that the. reaction of a soil by the Veitch method is changed by grinding the soil. Conner has found that keeping soils at different moisture contents alters their acidities. Heat is known to have an effect on the hydrogen ion concentration of a soil. In a previous paper the present writer reported a soil giving an acid reaction by the Hopkins potassium-nitrate method when, under field conditions, limestone fragments varying in size from a kernel of wheat to 2 cm. in diameter were present. The first step in
