Growing Coffee (Arabica) in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Turkana County is a challenging environment for Coffee (Arabica) (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 7.95 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 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Coffee (Arabica) prefers loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. Turkana receives approximately 300 mm/year — well below Coffee (Arabica)'s minimum of 1000 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Coffee (Arabica) is the #102 soil match of the 106 crops we assess for Turkana County. Coffee (Arabica)'s full potential is about 800 kg/acre (~KES 96,000/acre at KES 120/kg), but at Turkana's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.

Better matched to Turkana's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
