Growing Mango in Siaya

Soil suitability analysis based on Siaya's nutrient profile

Siaya County is a solid choice for Mango, with a soil-match score of 64/100. At an average pH of 5.33 the soil is moderately acidic, below Mango's preferred 5.5–8.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.2 g/kg, P 12.1 mg/kg, K 134 mg/kg against this crop's low/low/medium demand — so the fertilizer plan below prioritises closing that deficit. Mango prefers sandy soils, while Siaya is largely clay loam, so drainage and organic-matter management matter more here. At current prices (about KES 10/kg) and a typical 2,800 kg/acre yield, a well-managed Mango crop here can gross roughly KES 28,000 per acre.
