Very high Mg uptake occurs at pod development and supports the longevity of leaf area. Oilseed rape plants react on Mg deficiency with reduction of leaf area and interveinal chlorosis on older leaves in severe cases.
Sulfur deficiency is mostly detected on younger leaves or light yellow to white flowers. Sulfur supports better crop growth and reduces plant losses over winter. Sulfur enhances flowering and also maturity. Seed yield and oil content of seed are increased.
