Growing Chickpeas in Kiambu
Soil suitability analysis based on Kiambu's nutrient profile
Generally not ideal — Kiambu is poorly suited to Chickpeas. Kiambu's soil (pH 5.28, strongly acidic) gives Chickpeas a suitability score of 35/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Kiambu County is a challenging environment for Chickpeas (soil-match score 35/100) and will need significant amendment before planting. At an average pH of 5.28 the soil is moderately acidic, below Chickpeas's preferred 5.5–8 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 Chickpeas's requirements, so a maintenance fertilizer programme is enough. Chickpeas prefers sandy loam soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Chickpeas is the #99 soil match of the 106 crops we assess for Kiambu County. Chickpeas's full potential is about 600 kg/acre (~KES 120,000/acre at KES 200/kg), but at Kiambu's 35/100 suitability a realistic target here is closer to 263 kg/acre (~KES 52,600/acre) unless the constraints above are addressed.
Better matched to Kiambu's soil: Macadamia, Avocado, and Pineapple — each scores higher on the same soil.
