Growing Foxtail Millet in Kwale
Soil suitability analysis based on Kwale's nutrient profile
Kwale County is well suited to Foxtail Millet, scoring 83/100 on ShambaIQ's soil-match model. Local soils average pH 6.76 — neutral and inside the 5.5–7.5 band Foxtail Millet prefers, so no lime is usually required. The main gap is phosphorus — measured at N 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's low/medium/low demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Foxtail Millet, which favours sandy loam. At current prices (about KES 50/kg) and a typical 700 kg/acre yield, a well-managed Foxtail Millet crop here can gross roughly KES 35,000 per acre.
