Soil requirements

Optimizing soil and fertilizers for Onion in Kenya

To achieve maximum yields when farming onion in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 6 to 7. Soils that fall outside this range can lock out essential macro and micro-nutrients, leading to stunted growth or crop failure. For acidic soils, applying dolomitic or calcitic agricultural lime is recommended at least 30 days before planting to normalize acidity.

Fertilizer application should be calibrated based on the crop’s nutrient demands. Onion has a high nitrogen requirement, high phosphorus requirement, and medium potassium demand. Using certified seed varieties suited for your specific altitude and rainfall pattern, combined with a precise basal and top-dressing program (such as applying a balanced NPK compound), ensures high crop quality and protects your overall farm investment.
