Growing Baby Corn in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Makueni County is a solid choice for Baby Corn, with a soil-match score of 69/100. At an average pH of 7.5 the soil sits above Baby Corn'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/high/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Baby Corn, which favours loam. Baby Corn's full potential is about 4,000 kg/acre (~KES 320,000/acre at KES 80/kg), but at Makueni's 69/100 suitability a realistic target here is closer to 3,450 kg/acre (~KES 276,000/acre) unless the constraints above are addressed.
