Growing Radish in Taita Taveta
Soil suitability analysis based on Taita Taveta's nutrient profile
Taita Taveta County is well suited to Radish, scoring 89/100 on ShambaIQ's soil-match model. Local soils average pH 6.64 — neutral and inside the 6–7.5 band Radish prefers, so no lime is usually required. The main gap is potassium — measured at N 0.97 g/kg, P 12.9 mg/kg, K 104 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly loam soils suit Radish, which favours sandy loam. At current prices (about KES 40/kg) and a typical 8,000 kg/acre yield, a well-managed Radish crop here can gross roughly KES 320,000 per acre.
