Growing Courgette (Zucchini) in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Nyandarua County is a solid choice for Courgette (Zucchini), with a soil-match score of 63/100. At an average pH of 5.38 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 potassium — measured at N 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Courgette (Zucchini) prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. Courgette (Zucchini)'s full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Nyandarua's 63/100 suitability a realistic target here is closer to 9,450 kg/acre (~KES 472,500/acre) unless the constraints above are addressed.
