Growing Aloe Vera in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Nyandarua County is a challenging environment for Aloe Vera (soil-match score 36/100) and will need significant amendment before planting. At an average pH of 5.38 the soil is moderately acidic, below Aloe Vera's preferred 6–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Aloe Vera's requirements, so a maintenance fertilizer programme is enough. Aloe Vera prefers sandy loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. Aloe Vera's full potential is about 12,000 kg/acre (~KES 480,000/acre at KES 40/kg), but at Nyandarua's 36/100 suitability a realistic target here is closer to 5,400 kg/acre (~KES 216,000/acre) unless the constraints above are addressed.
