Growing Cape Gooseberry in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for Cape Gooseberry (soil-match score 8/100) and will need significant amendment before planting. At an average pH of 8.28 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 0.67 g/kg, P 42.1 mg/kg, K 387 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 Samburu is largely sandy, so drainage and organic-matter management matter more here. Samburu receives approximately 350 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 Samburu's 8/100 suitability a realistic target here is closer to 500 kg/acre (~KES 60,000/acre) unless the constraints above are addressed.
