Growing Courgette (Zucchini) in Meru

Soil suitability analysis based on Meru's nutrient profile

Quick answer

Yes, with the right inputs — Meru is moderately suited to Courgette (Zucchini). Meru's soil (pH 4.88, strongly acidic) gives Courgette (Zucchini) a suitability score of 61/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Meru County is a solid choice for Courgette (Zucchini), with a soil-match score of 61/100. At an average pH of 4.88 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 (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Courgette (Zucchini)'s requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Courgette (Zucchini), which favours loam. On ShambaIQ's soil-match model, Courgette (Zucchini) is the #49 soil match of the 106 crops we assess for Meru County. Courgette (Zucchini)'s full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Meru's 61/100 suitability a realistic target here is closer to 9,150 kg/acre (~KES 457,500/acre) unless the constraints above are addressed.
