The relation between corp growth and three phases of soil was studied. Corn, selected for the experiment was in the 1st and the 3rd farms of our Daily College. The soil belongs to Diluvial formation and its soil class is clay. There is not a definite relation between the quality of corn growth and the morphological properties of soil profiles. The ground water level at a place where corn growth is good, is low, while where corn growth is poor its level is very high. Definite relation between the quality of corn growth and the amount and kind of chemical nutrients of soil can not be recognized. As the corn plant demands much soil air for its growth, the lack of soil air, which results from the rain fall in August and the high ground water level in the farms, has great influence upon the growth of corn.
