Growing Lettuce in Makueni
Soil suitability analysis based on Makueni's nutrient profile
Yes, with the right inputs — Makueni is moderately suited to Lettuce. Makueni's soil (pH 7.5, alkaline) gives Lettuce a suitability score of 71/100. Match fertilizer to Makueni's nitrogen and phosphorus levels for the best result.
Makueni County is a solid choice for Lettuce, with a soil-match score of 71/100. At an average pH of 7.5 the soil sits above Lettuce's preferred 6–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.86 g/kg, P 29.6 mg/kg, K 351 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Lettuce, which favours loam. On ShambaIQ's soil-match model, Lettuce is the #40 soil match of the 106 crops we assess for Makueni County. Lettuce's full potential is about 7,000 kg/acre (~KES 350,000/acre at KES 50/kg), but at Makueni's 71/100 suitability a realistic target here is closer to 6,213 kg/acre (~KES 310,650/acre) unless the constraints above are addressed.
