Growing Dragon Fruit in Meru
Soil suitability analysis based on Meru's nutrient profile
Meru County is a solid choice for Dragon Fruit, with a soil-match score of 70/100. At an average pH of 4.88 the soil is strongly acidic, below Dragon Fruit's preferred 5.5–7 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 Dragon Fruit's requirements, so a maintenance fertilizer programme is enough. Dragon Fruit prefers sandy loam soils, while Meru is largely clay loam, so drainage and organic-matter management matter more here. Dragon Fruit's full potential is about 5,000 kg/acre (~KES 2,500,000/acre at KES 500/kg), but at Meru's 70/100 suitability a realistic target here is closer to 4,375 kg/acre (~KES 2,187,500/acre) unless the constraints above are addressed.
