Growing Watermelon in Busia
Soil suitability analysis based on Busia's nutrient profile
Generally not ideal — Busia is poorly suited to Watermelon. Busia's soil (pH 5.29, strongly acidic) gives Watermelon a suitability score of 34/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Busia County is a challenging environment for Watermelon (soil-match score 34/100) and will need significant amendment before planting. At an average pH of 5.29 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 (0.91 g/kg), phosphorus (16.6 mg/kg) and potassium (175 mg/kg) all meet Watermelon's requirements, so a maintenance fertilizer programme is enough. Watermelon prefers sandy soils, while Busia 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 Busia's 34/100 suitability a realistic target here is closer to 6,375 kg/acre (~KES 63,750/acre) unless the constraints above are addressed.
