Growing Courgette (Zucchini) in Marsabit
Soil suitability analysis based on Marsabit's nutrient profile
Generally not ideal — Marsabit is poorly suited to Courgette (Zucchini). Marsabit's soil (pH 8.22, alkaline) gives Courgette (Zucchini) a suitability score of 18/100. Match fertilizer to Marsabit's nitrogen and phosphorus levels for the best result.
Marsabit County is a challenging environment for Courgette (Zucchini) (soil-match score 18/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Courgette (Zucchini)'s preferred 5.8–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.52 g/kg, P 37.3 mg/kg, K 420 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 Marsabit is largely sandy, so drainage and organic-matter management matter more here. Marsabit receives approximately 300 mm/year — well below Courgette (Zucchini)'s minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Courgette (Zucchini) is the #41 soil match of the 106 crops we assess for Marsabit County. Courgette (Zucchini)'s full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Marsabit's 18/100 suitability a realistic target here is closer to 2,700 kg/acre (~KES 135,000/acre) unless the constraints above are addressed.
Better matched to Marsabit's soil: Sisal, Chia, and Aloe Vera — each scores higher on the same soil.
