Effect of gypsum and elemental sulphur on calcium and sulphur content of rutabagas in podzolic soils

Abstract

Both studies and information are lacking concerning Ca and S nutrition of rutabagas (Brassica napobrassica Mill). Five field studies were conducted to determine yield response of rutabagas to soil-applied gypsum (CaSO4-2H2O), lime (calcite) and elemental S on sandy loam to loamy sand Orthic Podzols in Prince Edward Island. Marketable yield of rutabagas was not affected by addition of Ca or S amendments. Gypsum increased the S content of rutabaga leaf tissue and reduced soil pH. In this study, a soil extractable Ca level of at least 318 μg g-1 soil appears adequate to support rutabaga growth.
