In a greenhouse study, seedling dry weights and uptake of Zn, K, Mg, and Ca were increased by applying 1 ppm of Zn to Caddo silt loam soil fertilized with 123 ppm of N, 0.31 meq of K/100 g, and varying amounts of P and lime. Zinc interacted with P and lime to alter N uptake. Zinc uptake rose with increasing amounts of Zn and available P in the soil at harvest, but declined with increasing levels of exchangeable Mg, K, and Ca.
