Growing Cashew Nuts in Homa Bay

Soil suitability analysis based on Homa Bay's nutrient profile

Homa Bay County is a challenging environment for Cashew Nuts (soil-match score 22/100) and will need significant amendment before planting. Local soils average pH 5.27 — moderately acidic and inside the 5–7.5 band Cashew Nuts prefers, so no lime is usually required. The main gap is potassium — measured at N 1.05 g/kg, P 13.8 mg/kg, K 147 mg/kg against this crop's low/low/medium demand — so the fertilizer plan below prioritises closing that deficit. Cashew Nuts prefers sandy soils, while Homa Bay is largely clay loam, so drainage and organic-matter management matter more here. At 1200 m, the county sits above Cashew Nuts's preferred altitude ceiling of 700 m, where frost risk and cold nights reduce the crop's productivity. At current prices (about KES 275/kg) and a typical 900 kg/acre yield, a well-managed Cashew Nuts crop here can gross roughly KES 247,500 per acre.
