Growing Courgette (Zucchini) in Nyeri

Soil suitability analysis based on Nyeri's nutrient profile

Nyeri County is a solid choice for Courgette (Zucchini), with a soil-match score of 72/100. At an average pH of 5.23 the soil is moderately acidic, below Courgette (Zucchini)'s preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen and potassium — measured at N 1.09 g/kg, P 15.5 mg/kg, K 192 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. Courgette (Zucchini) prefers loam soils, while Nyeri is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 50/kg) and a typical 12,000 kg/acre yield, a well-managed Courgette (Zucchini) crop here can gross roughly KES 600,000 per acre.
