Growing Watermelon in Kericho
Soil suitability analysis based on Kericho's nutrient profile
Generally not ideal — Kericho is poorly suited to Watermelon. Kericho's soil (pH 5.94, slightly acidic) gives Watermelon a suitability score of 23/100. Match fertilizer to Kericho's nitrogen and phosphorus levels for the best result.
Kericho County is a challenging environment for Watermelon (soil-match score 23/100) and will need significant amendment before planting. At an average pH of 5.94 the soil is slightly acidic to near-neutral, below Watermelon's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.34 g/kg), phosphorus (23.7 mg/kg) and potassium (225 mg/kg) all meet Watermelon's requirements, so a maintenance fertilizer programme is enough. Watermelon prefers sandy soils, while Kericho is largely clay, so drainage and organic-matter management matter more here. At 2000 m, the county sits above Watermelon's preferred altitude ceiling of 1500 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Watermelon is the #102 soil match of the 106 crops we assess for Kericho County. Watermelon's full potential is about 15,000 kg/acre (~KES 150,000/acre at KES 10/kg), but at Kericho's 23/100 suitability a realistic target here is closer to 4,313 kg/acre (~KES 43,130/acre) unless the constraints above are addressed.
Better matched to Kericho's soil: Kale (Sukuma Wiki), Sweet Potato, and Wambugu Apples — each scores higher on the same soil.

| Factor | Kericho soil | Watermelon needs | Status |
|---|---|---|---|
| pH | 5.94 | 6–7.5 | Adjust |
| Nitrogen | 1.34 g/kg | min 0.8 g/kg | OK |
| Phosphorus | 23.7 mg/kg | min 12 mg/kg | OK |
| Potassium | 225 mg/kg | min 150 mg/kg | OK |
| Rainfall | 1,800 mm | 300–700 mm | High |
| Altitude | 2,000 m | 0–1,500 m | High |
Top dressing guide
Kericho's nitrogen (1.34 g/kg) already meets Watermelon's 0.8 g/kg requirement, so this is a maintenance rate.
