Growing Guava in Kisii
Soil suitability analysis based on Kisii's nutrient profile
Yes, with the right inputs — Kisii is moderately suited to Guava. Kisii's soil (pH 5.21, strongly acidic) gives Guava a suitability score of 71/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Kisii County is a solid choice for Guava, with a soil-match score of 71/100. At an average pH of 5.21 the soil is moderately acidic, below Guava's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.09 g/kg), phosphorus (13.1 mg/kg) and potassium (151 mg/kg) all meet Guava's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Guava, which favours loam. On ShambaIQ's soil-match model, Guava is the #24 soil match of the 106 crops we assess for Kisii County. Guava's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Kisii's 71/100 suitability a realistic target here is closer to 8,875 kg/acre (~KES 532,500/acre) unless the constraints above are addressed.
