Growing Cucumber in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Makueni County is a solid choice for Cucumber, with a soil-match score of 69/100. At an average pH of 7.5 the soil sits above Cucumber's preferred 5.8–7 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/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Cucumber, which favours loam. Cucumber's full potential is about 12,000 kg/acre (~KES 480,000/acre at KES 40/kg), but at Makueni's 69/100 suitability a realistic target here is closer to 10,350 kg/acre (~KES 414,000/acre) unless the constraints above are addressed.
