Growing Cape Gooseberry in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Turkana County is a challenging environment for Cape Gooseberry (soil-match score 1/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Cape Gooseberry's preferred 6–7.5 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 medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Cape Gooseberry 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 Cape Gooseberry's minimum of 700 mm — so supplemental irrigation would be essential for this crop. Cape Gooseberry's full potential is about 5,000 kg/acre (~KES 600,000/acre at KES 120/kg), but at Turkana's 1/100 suitability a realistic target here is closer to 63 kg/acre (~KES 7,560/acre) unless the constraints above are addressed.
