Available in PDF, EPUB and Kindle. Book excerpt: The relationships between zinc, iron, and phosphorus in sweet corn were investigated under field and greenhouse conditions. The soils used in this study (both acid and calcareous) were low in available zinc and phosphorus. The experiments received standard, uniform rates of nitrogen potassium, magnesium, and sulphur. Corn was used as an indicator crop in all experiments. Plant samples from the field experiments consisted of whole plants collected at six weeks and index leaves collected at silking stage, while the middle three leaves were collected at eight weeks from the greenhouse experiment. The plants that showed visual zinc deficiency symptoms contained very high iron contents and responded to applied zinc. When either phosphorus or soil acidity was limiting growth, no response was obtained from applied zinc and the iron levels were low. Applications of phosphorus and lime both apparently induced a zinc deficiency and a high iron uptake by the plant. Under these conditions marked growth responses to applied zinc were obtained and sharp reductions in iron contents of the plants were noted. These results are contradictory to those reported by other workers for the effect of phosphorus and lime on the uptake of iron; normally, these two materials reduce the uptake of iron by the plant. This was actually the case when zinc was adequate but the reverse was true when a zinc deficiency existed. To explain these results, the hypothesis was advanced that one characteristic of a zinc-deficient plant is a high iron content. Although the actual lime and phosphorus effect is probably a reduction of iron uptake, their effect on creating a zinc deficiency and the associated high iron content was most likely the over-riding factor.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of zinc and phosphorus treatments on five different plant species were investigated in a greenhouse experiment. A second greenhouse experiment extended these investigations in sweet corn over a broad range of phosphorus treatments with and without adequate zinc nutrition to study phosphorus induced zinc deficiency. The plant responses measured in each experiment were yield, content and uptake of zinc, phosphorus, iron and manganese. The susceptibility of the five plant species to zinc deficiency ranged from very severe in sweet corn and bush beans, moderately to slightly severe in potatoes and tomatoes and tolerant in wheat. The soils used throughout these experiments were both phosphorus and zinc deficient. Phosphorus deficiency was the most limiting factor to plant growth and zinc deficiency could not be observed in susceptible species until phosphorus needs were met. In no instance did phosphorus application interfere with zinc uptake and in fact, higher levels of applied phosphorus increased the total uptake of zinc. Zinc deficiency nevertheless resulted because the supply of available zinc in these soils was inadequate to meet plant needs. Phosphorus content was greatly elevated in susceptible species when zinc deficiency symptoms were observed. Iron and manganese contents were greatly elevated in zinc deficient sweet corn whereas an increased content of these elements occurred only in the most severely zinc deficient bush beans and not at all in other species.
