Abstract
An investigation was carried out to determine the relative intake of elements by calciphilic, intermediate, and calciphobic plants when grown on acid and on basic soil. 9 important agronomic crop plants and one vegetable were grown in crocks of Chenango loam of pH 4.4 and 7.3 [plus or minus]. These plants were analyzed for total ash, insoluble ash, Ca, Mg, N, P, K, and Fe. The total ash and the intake of Ca, Mg, N, and Fe increased when Ca(OH)2 was added to the acid soil to raise the pH. In general, the intake of P decreased with the addition of Ca. K increased or decreased depending largely upon the species of plant grown. The plants grouped as intermediates were consistent in their intake of elements. The calciphobic plants were comparatively consistent, and the calcipniles showed great variability in their absorption of elements. On the basis of % composition, all the plants at higher pH contained more Ca than at lower pH; also under the same condition 80% of all the plants contained more Mg, 90% contained more N, and 80% contained more Fe; but 70% of the plants obtained more P from the acid soil than from the less acid soil.
