The Calcium and Phosphorus Content of Some Alabama Vegetables

Abstract

Analyses were made of a number of Alabama vegetables of which some were grown in the greenhouse on five different soil types with five different rates of superphosphate treatment, and some were grown in the field on one soil type with one fertilizer treatment. The calcium and phosphorus content of a given vegetable varies widely, usually in opposite directions, so that the Ca:P ratio varies markedly. Increased rates of superphosphate produce a regular increase in the phosphorus content but a small change in calcium.
