Growing Radish in Machakos

Soil suitability analysis based on Machakos's nutrient profile

Quick answer

Yes — Machakos is well suited to Radish. Machakos's soil (pH 7.03, near-neutral) gives Radish a suitability score of 89/100. Match fertilizer to Machakos's nitrogen and phosphorus levels for the best result.

Machakos County is well suited to Radish, scoring 89/100 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. Nitrogen (0.82 g/kg), phosphorus (31.4 mg/kg) and potassium (338 mg/kg) all meet Radish's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Radish, which favours sandy loam. On ShambaIQ's soil-match model, Radish is the #17 soil match of the 106 crops we assess for Machakos 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.
