Growing Okra in Embu

Soil suitability analysis based on Embu's nutrient profile

Okra can be grown in Embu County, but the soil scores 53/100 and needs targeted management to reach full potential. At an average pH of 5.1 the soil is moderately acidic, below Okra's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.04 g/kg), phosphorus (12.6 mg/kg) and potassium (194 mg/kg) all meet Okra's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Okra, which favours loam. Okra's full potential is about 5,000 kg/acre (~KES 300,000/acre at KES 60/kg), but at Embu's 53/100 suitability a realistic target here is closer to 3,313 kg/acre (~KES 198,780/acre) unless the constraints above are addressed.
