Growing Finger Millet in Kiambu

Soil suitability analysis based on Kiambu's nutrient profile

Kiambu County is well suited to Finger Millet, scoring 85/100 on ShambaIQ's soil-match model. Local soils average pH 5.28 — moderately acidic and inside the 5–7 band Finger Millet prefers, so no lime is usually required. Nitrogen (1.01 g/kg), phosphorus (13.7 mg/kg) and potassium (169 mg/kg) all meet Finger Millet's requirements, so a maintenance fertilizer programme is enough. Finger Millet prefers sandy soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 60/kg) and a typical 600 kg/acre yield, a well-managed Finger Millet crop here can gross roughly KES 36,000 per acre.
