Growing Coffee (Arabica) in Kajiado

Soil suitability analysis based on Kajiado's nutrient profile

Kajiado County is a challenging environment for Coffee (Arabica) (soil-match score 19/100) and will need significant amendment before planting. At an average pH of 6.55 the soil sits above Coffee (Arabica)'s preferred 5–6 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 (Arabica), which favours loam. Kajiado receives approximately 500 mm/year — well below Coffee (Arabica)'s minimum of 1000 mm — so supplemental irrigation would be essential for this crop. Coffee (Arabica)'s full potential is about 800 kg/acre (~KES 96,000/acre at KES 120/kg), but at Kajiado's 19/100 suitability a realistic target here is closer to 190 kg/acre (~KES 22,800/acre) unless the constraints above are addressed.
