Growing Watermelon in Migori

Soil suitability analysis based on Migori's nutrient profile

Migori County is a challenging environment for Watermelon (soil-match score 35/100) and will need significant amendment before planting. At an average pH of 5.43 the soil is moderately acidic, below Watermelon's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (169 mg/kg) all meet Watermelon's requirements, so a maintenance fertilizer programme is enough. Watermelon prefers sandy soils, while Migori is largely clay loam, so drainage and organic-matter management matter more here. At current prices (about KES 10/kg) and a typical 5,500 kg/acre yield, a well-managed Watermelon crop here can gross roughly KES 55,000 per acre.
