Growing Guava in Kiambu

Soil suitability analysis based on Kiambu's nutrient profile

Kiambu County is a solid choice for Guava, with a soil-match score of 73/100. At an average pH of 5.28 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 (1.01 g/kg), phosphorus (13.7 mg/kg) and potassium (169 mg/kg) all meet Guava's requirements, so a maintenance fertilizer programme is enough. Guava prefers loam soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 60/kg) and a typical 10,000 kg/acre yield, a well-managed Guava crop here can gross roughly KES 600,000 per acre.
