Growing Stevia in Bungoma

Soil suitability analysis based on Bungoma's nutrient profile

Quick answer

Yes, with the right inputs — Bungoma is moderately suited to Stevia. Bungoma's soil (pH 5.56, slightly acidic) gives Stevia a suitability score of 72/100. Match fertilizer to Bungoma's nitrogen and phosphorus levels for the best result.

Bungoma County is a solid choice for Stevia, with a soil-match score of 72/100. At an average pH of 5.56 the soil is slightly acidic to near-neutral, below Stevia's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen — measured at N 1.12 g/kg, P 15.7 mg/kg, K 161 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Stevia, which favours loam. On ShambaIQ's soil-match model, Stevia is the #52 soil match of the 106 crops we assess for Bungoma County. At current prices (about KES 200/kg) and a typical 3,000 kg/acre yield, a well-managed Stevia crop here can gross roughly KES 600,000 per acre.

Bags per acre in Bungoma
0.50.3

Bungoma's nitrogen (1.12 g/kg) is 93% of the 1.2 g/kg Stevia needs, so the standard 0.3 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
