Growing Watermelon in Taita Taveta

Soil suitability analysis based on Taita Taveta's nutrient profile

Quick answer

Yes — Taita Taveta is well suited to Watermelon. Taita Taveta's soil (pH 6.64, near-neutral) gives Watermelon a suitability score of 89/100. Match fertilizer to Taita Taveta's nitrogen and phosphorus levels for the best result.

Taita Taveta County is well suited to Watermelon, scoring 89/100 on ShambaIQ's soil-match model. Local soils average pH 6.64 — neutral and inside the 6–7.5 band Watermelon prefers, so no lime is usually required. The main gap is potassium — measured at N 0.97 g/kg, P 12.9 mg/kg, K 104 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Watermelon prefers sandy soils, while Taita Taveta is largely loam, so drainage and organic-matter management matter more here. At current prices (about KES 10/kg) and a typical 15,000 kg/acre yield, a well-managed Watermelon crop here can gross roughly KES 150,000 per acre.
