A field study was undertaken to determine effective ways of introducing zinc into the field bean plant when grown on calcareous soils which are low in available zinc. Three locations with soils of low, medium and high calcium carbonate content were selected as experimental sites.
A total of 16 treatments were used. Three rates of zinc sulfate were applied by both the side-dress and plow-down methods. Treatments of manganese sulfate and Chel 330 iron were included to determine the effect if any of these minor elements on the uptake of zinc.
