Growing Guava in Murang'a
Soil suitability analysis based on Murang'a's nutrient profile
Yes, with the right inputs — Murang'a is moderately suited to Guava. Murang'a's soil (pH 5.03, strongly acidic) gives Guava a suitability score of 67/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Murang'a County is a solid choice for Guava, with a soil-match score of 67/100. At an average pH of 5.03 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 (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (168 mg/kg) all meet Guava's requirements, so a maintenance fertilizer programme is enough. Guava prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Guava is the #34 soil match of the 106 crops we assess for Murang'a County. Guava's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Murang'a's 67/100 suitability a realistic target here is closer to 8,375 kg/acre (~KES 502,500/acre) unless the constraints above are addressed.
