Two experiments were installed in the greenhouse to study the relationships between phosphate fertilization, liming and zinc fertilization. One experiment used a red latosol soil while the other used a dark brown acid soil. Hybrid corn 'AG 206' was used to plant both experiments.
The data collected consisted of dry matter productions, level of zinc in the leaves, stems and tootes of the corn as well as the P/Zn and Ca/Zn ratios in the leaves.
Phosphate fertilization and liming lowed the level of zinc in the corn leaves to a point equal to or lower than 14 ppm.
These leves were below 80% of the maximum yields of the experiments.
The application of 4.5 ppm of zinc to the soil was adequate to raise the level of zinc in the leaves above the critical level. It also increase the production of the corn since without added zinc, the production was limited by a zinc de- ficiency.
The phosphorus and zinc interaciotion, which ocurred primarily in the roots of the plant, reduced the translocation of zinc to the leaves.
The interaction between liming and zinc ocurred prior to the absorption of zinc by the plant. It aprears that there are ratios between phosphorus and zinc between calcium and zinc in the leaves which are critical to good plant growrh.
The critical P/Zn ratio is between 300 and 470 and the critical Ca/Zn ratio between 455-640.
