Growing Cassava in Kajiado
Soil suitability analysis based on Kajiado's nutrient profile
Kajiado County is well suited to Cassava, scoring 83/100 on ShambaIQ's soil-match model. Local soils average pH 6.55 — neutral and inside the 4.5–7 band Cassava prefers, so no lime is usually required. Nitrogen (0.97 g/kg), phosphorus (20.6 mg/kg) and potassium (257 mg/kg) all meet Cassava's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Cassava, which favours sandy. At current prices (about KES 15/kg) and a typical 6,000 kg/acre yield, a well-managed Cassava crop here can gross roughly KES 90,000 per acre.
