Abstract
Abstract There are soil series that contain free calcium carbonate (CaCO3) within fields where the surrounding pHs of the soil series are slightly acid. The objective was to study corn (Zea mays L.) grain yield response to zinc (Zn) fertilizer on different soil series within fields. The study was conducted at 12 sites between 1998 and 2000. Treatments were 0 and 5.6 kg Zn ha−1 applied in bands to field‐length strips of corn and replicated four times. Multiple soil series were identified at each site, and treatment pairs were located within them. Grain yields, whole plant (V6 to V10 growth stage), and grain Zn content and uptake were measured. The most common result was no response to Zn application. However, significant yield decreases occurred on some soils as a result of Zn application in two situations: on soils with high soil‐test Zn or on soils with low soil‐test Zn and high pH.
