Growing Lettuce in Taita Taveta

Soil suitability analysis based on Taita Taveta's nutrient profile

Lettuce can be grown in Taita Taveta County, but the soil scores 46/100 and needs targeted management to reach full potential. Local soils average pH 6.64 — neutral and inside the 6–7 band Lettuce prefers, so no lime is usually required. The main gap is nitrogen and potassium — measured at N 0.97 g/kg, P 12.9 mg/kg, K 104 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly loam soils suit Lettuce, which favours loam. Lettuce's full potential is about 7,000 kg/acre (~KES 350,000/acre at KES 50/kg), but at Taita Taveta's 46/100 suitability a realistic target here is closer to 4,025 kg/acre (~KES 201,250/acre) unless the constraints above are addressed.
