Growing Radish in Mombasa
Soil suitability analysis based on Mombasa's nutrient profile
Generally not ideal — Mombasa is poorly suited to Radish. Mombasa's soil (pH 6.24, slightly acidic) gives Radish a suitability score of 1/100. Match fertilizer to Mombasa's nitrogen and phosphorus levels for the best result.
Mombasa County is a challenging environment for Radish (soil-match score 1/100) 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 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Radish, which favours sandy loam. At 50 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 #68 soil match of the 106 crops we assess for Mombasa County. Radish's full potential is about 8,000 kg/acre (~KES 320,000/acre at KES 40/kg), but at Mombasa's 1/100 suitability a realistic target here is closer to 100 kg/acre (~KES 4,000/acre) unless the constraints above are addressed.
Better matched to Mombasa's soil: Finger Millet, Cashew Nuts, and Napier Grass — each scores higher on the same soil.

Top dressing guide
Mombasa's nitrogen (0.95 g/kg) already meets Radish's 0.8 g/kg requirement, so this is a maintenance rate.
