Abstract
SummaryThe growth of oat seedlings in West-moreland silt loam, more acid than pH 6.0, may be materially retarded by the presence of a few hundred parts of zinc per million parts of soil. The injurious effects of the zinc may be prevented by the application of calcium carbonate. The detrimental effects of 800 parts of zinc per million to oat seedlings were prevented in three different samples of soil by incorporating sufficient calcium carbonate to reduce soil acidity to that corresponding to pH 6.0. The results of analysis of the tops of oat seedlings indicate that the concentration of zinc in the soil solution is decreased to a non-toxic level in the neighborhood of pH 6.0 and approaches a minimum at pH 6.5. Some practical implications of these findings are discussed.
