Growing Aloe Vera in Siaya
Soil suitability analysis based on Siaya's nutrient profile
Possible but challenging — Siaya is only marginally suited to Aloe Vera. Siaya's soil (pH 5.33, strongly acidic) gives Aloe Vera a suitability score of 41/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Siaya County is a challenging environment for Aloe Vera (soil-match score 41/100) and will need significant amendment before planting. At an average pH of 5.33 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. The main gap is potassium — measured at N 1.2 g/kg, P 12.1 mg/kg, K 134 mg/kg against this crop's low/low/medium demand — so the fertilizer plan below prioritises closing that deficit. Aloe Vera prefers sandy loam soils, while Siaya is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Aloe Vera is the #96 soil match of the 106 crops we assess for Siaya County. Aloe Vera's full potential is about 12,000 kg/acre (~KES 480,000/acre at KES 40/kg), but at Siaya's 41/100 suitability a realistic target here is closer to 6,150 kg/acre (~KES 246,000/acre) unless the constraints above are addressed.
Better matched to Siaya's soil: Macadamia, Pineapple, and Avocado — each scores higher on the same soil.

Top dressing guide
Siaya's nitrogen (1.2 g/kg) already meets Aloe Vera's 0.5 g/kg requirement, so this is a maintenance rate.
