Growing Cape Gooseberry in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Makueni County is a challenging environment for Cape Gooseberry (soil-match score 41/100) and will need significant amendment before planting. Local soils average pH 7.5 — alkaline and inside the 6–7.5 band Cape Gooseberry prefers, so no lime is usually required. Nitrogen (0.86 g/kg), phosphorus (29.6 mg/kg) and potassium (351 mg/kg) all meet Cape Gooseberry's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Cape Gooseberry, which favours loam. Cape Gooseberry's full potential is about 5,000 kg/acre (~KES 600,000/acre at KES 120/kg), but at Makueni's 41/100 suitability a realistic target here is closer to 2,563 kg/acre (~KES 307,560/acre) unless the constraints above are addressed.
