Abstract

In a pot experiment with corn plants, the higher the total carbonate content of the soil was, the lower was the dry matter yield, P-uptake, Zn-uptake and Zn-translocation. P-translocation was unaffected. Zn treatments had no effect on the dry matter yield, P-uptake or P-translocation. P-treatments significantly increased the dry matter yield and Zn-uptake and slightly increased Zn-translocation. The relationship between Zn-uptake and P-uptake by shoots or roots was always positive and in some cases it was significant.
