Growing Coffee (Robusta) in Kajiado
Soil suitability analysis based on Kajiado's nutrient profile
Generally not ideal — Kajiado is poorly suited to Coffee (Robusta). Kajiado's soil (pH 6.55, near-neutral) gives Coffee (Robusta) a suitability score of 8/100. Match fertilizer to Kajiado's nitrogen and phosphorus levels for the best result.
Kajiado County is a challenging environment for Coffee (Robusta) (soil-match score 8/100) and will need significant amendment before planting. At an average pH of 6.55 the soil sits above Coffee (Robusta)'s preferred 5–6.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.97 g/kg, P 20.6 mg/kg, K 257 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Coffee (Robusta), which favours loam. Kajiado receives approximately 500 mm/year — well below Coffee (Robusta)'s minimum of 1500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Coffee (Robusta) is the #105 soil match of the 106 crops we assess for Kajiado County. Coffee (Robusta)'s full potential is about 950 kg/acre (~KES 76,000/acre at KES 80/kg), but at Kajiado's 8/100 suitability a realistic target here is closer to 95 kg/acre (~KES 7,600/acre) unless the constraints above are addressed.
Better matched to Kajiado's soil: Sorghum, Cowpeas, and Pigeon Peas — each scores higher on the same soil.
