NUTRIENT INFORMATION
Carry out a nutrient analysis prior to planting. Onions typically require high phosphorus and potassium and lower nitrogen blends at planting (Compound C, Vegetable blend or equivalent). High basal rates can be required and often broadcasted and mixed into the soil. It is best to apply to the soil at least one week prior to planting/transplanting) to avoid fertilizer toxicity. Calcium Nitrate applications can be made as a topdressing throughout the season. Apply routinely at low rates.
