Growing Cape Gooseberry in Kirinyaga
Soil suitability analysis based on Kirinyaga's nutrient profile
Kirinyaga County is a solid choice for Cape Gooseberry, with a soil-match score of 67/100. At an average pH of 5.31 the soil is moderately acidic, below Cape Gooseberry's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.36 g/kg, P 12.5 mg/kg, K 177 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 Kirinyaga is largely clay, so drainage and organic-matter management matter more here. Cape Gooseberry's full potential is about 5,000 kg/acre (~KES 600,000/acre at KES 120/kg), but at Kirinyaga's 67/100 suitability a realistic target here is closer to 4,188 kg/acre (~KES 502,560/acre) unless the constraints above are addressed.
