Growing Aloe Vera in Kiambu
Soil suitability analysis based on Kiambu's nutrient profile
Possible but challenging — Kiambu is only marginally suited to Aloe Vera. Kiambu's soil (pH 5.28, strongly acidic) gives Aloe Vera a suitability score of 46/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Aloe Vera can be grown in Kiambu County, but the soil scores 46/100 and needs targeted management to reach full potential. At an average pH of 5.28 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 (1.01 g/kg), phosphorus (13.7 mg/kg) and potassium (169 mg/kg) all meet Aloe Vera's requirements, so a maintenance fertilizer programme is enough. Aloe Vera prefers sandy loam soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Aloe Vera is the #94 soil match of the 106 crops we assess for Kiambu County. Aloe Vera's full potential is about 12,000 kg/acre (~KES 480,000/acre at KES 40/kg), but at Kiambu's 46/100 suitability a realistic target here is closer to 6,900 kg/acre (~KES 276,000/acre) unless the constraints above are addressed.
Better matched to Kiambu's soil: Macadamia, Avocado, and Pineapple — each scores higher on the same soil.

Kiambu's nitrogen (1.01 g/kg) already meets Aloe Vera's 0.5 g/kg requirement, so this is a maintenance rate.
