Growing Coffee (Arabica) in Baringo

Soil suitability analysis based on Baringo's nutrient profile

Baringo County is a challenging environment for Coffee (Arabica) (soil-match score 20/100) and will need significant amendment before planting. At an average pH of 6.22 the soil sits above Coffee (Arabica)'s preferred 5–6 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (1.32 g/kg), phosphorus (23.4 mg/kg) and potassium (212 mg/kg) all meet Coffee (Arabica)'s requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Coffee (Arabica), which favours loam. Baringo receives approximately 700 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 Baringo's 20/100 suitability a realistic target here is closer to 200 kg/acre (~KES 24,000/acre) unless the constraints above are addressed.
