Show LARGER CROP ON RICH SOIL Startling Statement Made by Dr. Widt-soe Widt-soe In Paper Prepared for Dry Farm Congress. A plant growing on a rich soil can make twice as much growth with a given amount of water as a plant growing grow-ing on a poor soil. That was the startling statement made by Dr. Widtsoe of Utah in a paper prepared for the Dry Farming congress. He cited an experiment. Corn required 908 pounds of water to produce one pound dry matter; when the same field was manured It required but 612 pounds In other words, the field when manured ma-nured could produce a third more. He secured similar results by cultivation. Stirring the soil enervated plant food. It seems to be a good deal like the results that might be expected from feeding a man thin or thick soup. These facts are Important to the dry farmer; but also to the humid region farmer and to the irrigator. |
