Abstract

Various investigators have shown that the soil atmosphere possesses a higher concentration of carbon dioxide when a legume is grown than when a non-legume is grown. The beneficial effects to crops following certain legumes have been attributed in part, at least, to the carbon dioxide evolved by the roots of the legumes. The significance of carbon dioxide in the soil air in breaking down minerals and making phosphorus available to plants, is an important question from the practical standpoint.
