Summary
The effects and interactions of two concentrations of phosphorus and calcium, and four concentrations of manganese, were investigated in cotton grown in quartz chips with nutrient solutions. Too little phosphorus and calcium and too much manganese caused abnormal plants, but with suitable concentrations of the three nutrients plants were healthy. With the largest concentrations of the three nutrients together much of the manganese taken up precipitated as nodules in the leaves; a large concentration of calcium seemed necessary for precipitation and to prevent harmful concentrations of mobile manganese in the plants. The results indicated that in plants grown with much manganese its concentration in leaves increased as more calcium and phosphorus were given when their mole ratio in the nutrient solution was less than 1; but the concentration of leaf manganese diminished when the ratio was greater than 1. re]19760401
