Phosphorus‐Zn interactions in fiber flax, Linum usitatissimum L., were studied in growth chambers by means of a two‐zone root technique and nutrient solutions. Zinc and P were added separately from each other and the other essential elements; therefore, any interactions that occurred between them or with other elements had to take place at root surfaces or within the plant. Increasing either Zn or P in the substrate increased the concentration and total uptake of the respective element in the roots and tops of the flax plants. When P was added first, Zn increased total P in the lower and upper roots and decreased total P in the tops. When Zn was added first, P increased total Zn in the lower roots and decreased total Zn in the tops. The results indicate that P and Zn react together within the roots in a manner that reduces either their mobility or solubility.
