Growing Capsicum in Embu
Soil suitability analysis based on Embu's nutrient profile
Yes, with the right inputs — Embu is moderately suited to Capsicum. Embu's soil (pH 5.1, strongly acidic) gives Capsicum a suitability score of 63/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Embu County is a solid choice for Capsicum, with a soil-match score of 63/100. At an average pH of 5.1 the soil is moderately acidic, below Capsicum's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.04 g/kg, P 12.6 mg/kg, K 194 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Capsicum, which favours loam. On ShambaIQ's soil-match model, Capsicum is the #45 soil match of the 106 crops we assess for Embu County. Capsicum's full potential is about 6,000 kg/acre (~KES 540,000/acre at KES 90/kg), but at Embu's 63/100 suitability a realistic target here is closer to 4,725 kg/acre (~KES 425,250/acre) unless the constraints above are addressed.

Top dressing guide
Embu's nitrogen (1.04 g/kg) is 87% of the 1.2 g/kg Capsicum needs, so the standard 0.5 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
