Growing Radish in Kitui

Soil suitability analysis based on Kitui's nutrient profile

Quick answer

Yes — Kitui is well suited to Radish. Kitui's soil (pH 7.03, near-neutral) gives Radish a suitability score of 88/100. Match fertilizer to Kitui's nitrogen and phosphorus levels for the best result.

Kitui County is well suited to Radish, scoring 88/100 on ShambaIQ's soil-match model. Local soils average pH 7.03 — neutral and inside the 6–7.5 band Radish prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.74 g/kg, P 30.5 mg/kg, K 339 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Radish, which favours sandy loam. On ShambaIQ's soil-match model, Radish is the #16 soil match of the 106 crops we assess for Kitui County. 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.
