Growing Tea in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Mombasa County is a challenging environment for Tea (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 6.24 the soil sits above Tea's preferred 4.5–6 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. Tea prefers clay soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. At 50 m, the county sits below Tea's preferred altitude range (1500–3000 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Tea is the #73 soil match of the 106 crops we assess for Mombasa County. Tea's full potential is about 2,200 kg/acre (~KES 55,000/acre at KES 25/kg), but at Mombasa's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.

Better matched to Mombasa's soil: Finger Millet, Cashew Nuts, and Napier Grass — each scores higher on the same soil.
