Influence of Applied Sulfur on Availability of Soil Nutrients for Corn (Zea mays L.) Nutrition
1966
Hassan, Nouri | Olson, R. A.
Influence of applied sulfur on soil properties and nutrient uptake was studied on three soils ranging from acid to calcareous with growth of corn in the greenhouse. The heaviest rate of 5,000 ppm S produced toxic effects on the acid and neutral soils, a consequence of sharp pH reduction and excessive S and Manganese uptake. Otherwise, S treatment had beneficial effects on: Phosphorus nutrition on neutral and calcareous soils; S and Mn nutrition (up to modest rate of S) on all soils; zinc in early nutrition on all soils with slight benefit carrying over to late harvest only on calcareous soil; iron nutrition on calcareous soil; and copper nutrition until early harvest with all soils and through late harvest with neutral and calcareous soils. With a low rate of 50 ppm S, mixing was more efficacious than banding on all soils.
