Growing Strawberry in Kirinyaga

Soil suitability analysis based on Kirinyaga's nutrient profile

Kirinyaga County is a solid choice for Strawberry, with a soil-match score of 74/100. At an average pH of 5.31 the soil is moderately acidic, below Strawberry's preferred 5.5–6.8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 1.36 g/kg, P 12.5 mg/kg, K 177 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Strawberry prefers loam soils, while Kirinyaga is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 200/kg) and a typical 6,000 kg/acre yield, a well-managed Strawberry crop here can gross roughly KES 1,200,000 per acre.
