Growing Finger Millet in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Nyandarua County is a solid choice for Finger Millet, with a soil-match score of 66/100. Local soils average pH 5.38 — moderately acidic and inside the 5–7 band Finger Millet prefers, so no lime is usually required. Nitrogen (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Finger Millet's requirements, so a maintenance fertilizer programme is enough. Finger Millet prefers sandy soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. Finger Millet's full potential is about 800 kg/acre (~KES 48,000/acre at KES 60/kg), but at Nyandarua's 66/100 suitability a realistic target here is closer to 660 kg/acre (~KES 39,600/acre) unless the constraints above are addressed.
