Growing Watermelon in Homa Bay

Soil suitability analysis based on Homa Bay's nutrient profile

Watermelon can be grown in Homa Bay County, but the soil scores 48/100 and needs targeted management to reach full potential. At an average pH of 5.27 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. 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 medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Watermelon prefers sandy soils, while Homa Bay is largely clay loam, so drainage and organic-matter management matter more here. Watermelon's full potential is about 15,000 kg/acre (~KES 150,000/acre at KES 10/kg), but at Homa Bay's 48/100 suitability a realistic target here is closer to 9,000 kg/acre (~KES 90,000/acre) unless the constraints above are addressed.
