Growing Radish in Kilifi

Soil suitability analysis based on Kilifi's nutrient profile

Kilifi County is a challenging environment for Radish (soil-match score 7/100) and will need significant amendment before planting. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 6–7.5 band Radish prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Radish, which favours sandy loam. At 150 m, the county sits below Radish's preferred altitude range (500–2500 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Radish is the #67 soil match of the 106 crops we assess for Kilifi County. Radish's full potential is about 8,000 kg/acre (~KES 320,000/acre at KES 40/kg), but at Kilifi's 7/100 suitability a realistic target here is closer to 700 kg/acre (~KES 28,000/acre) unless the constraints above are addressed.

Better matched to Kilifi's soil: Sesame (Simsim), Sorghum, and Finger Millet — each scores higher on the same soil.
