Growing Courgette (Zucchini) in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Laikipia County is a solid choice for Courgette (Zucchini), with a soil-match score of 69/100. At an average pH of 4.99 the soil is strongly acidic, below Courgette (Zucchini)'s preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 mg/kg) all meet Courgette (Zucchini)'s requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Courgette (Zucchini), which favours loam. Courgette (Zucchini)'s full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Laikipia's 69/100 suitability a realistic target here is closer to 10,350 kg/acre (~KES 517,500/acre) unless the constraints above are addressed.
