Growing Courgette (Zucchini) in Kirinyaga

Soil suitability analysis based on Kirinyaga's nutrient profile

Kirinyaga County is a solid choice for Courgette (Zucchini), with a soil-match score of 71/100. At an average pH of 5.31 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 1.36 g/kg, P 12.5 mg/kg, K 177 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 Kirinyaga 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 Kirinyaga's 71/100 suitability a realistic target here is closer to 10,650 kg/acre (~KES 532,500/acre) unless the constraints above are addressed.
