Micronutrient Availability in Three Soil Materials as Affected by Applications of Zinc, Lime, and Sulfur1

Abstract

Abstract

Three Nebraska soil materials were treated with S, CaCO3, and ZnSO4 and incubated or cropped with corn (Zea mays L.) in the greenhouse to determine essential factors affecting micronutrient release from these soils. The type of soil material had the greatest influence on plant dry matter production and nutrient composition. The application of Zn also showed important effects, but additions of S and CaCO3 had limited effect on most variables studied. The investigation indicates that increased attention must be given to the mineralogy of soils in order to discern their micronutrient-releasing ability for crop production.
